Protein Restriction Slows Progression of Mouse Model of Alzheimer’s Disease

Calorie restriction slows the progression of near all measurable aspects of degenerative aging, and improves near all measures of health. It extends life by up to 40% in mice, and one of the interesting challenges for the study of metabolism is to explain the mechanics of how it can improve health so greatly in humans while failing to extend life to the same degree as it does in shorter-lived mammals. There is a good evolutionary explanation for this phenomenon; the expected length of a naturally occurring famine is the same whether you are a mouse or a man, and thus life span changes in response to famine must be more dramatic in a shorter lived species in order to have a decent chance of surviving it to reproduce. But that doesn't tell us how it happens under the hood.

Some of the triggers for the metabolic changes of calorie restriction involve sensing protein levels. Maintaining the same calorie intake while reducing dietary protein levels captures some fraction of the full effects of calorie restriction, with methionine seemingly the most important triggering protein.

Here a noted calorie restriction researcher shows protein restriction to slow the progression of a mouse model of Alzheimer's disease - which is pretty much the expected result, given what we know so far of how the effects of protein restriction map to those of calorie restriction:

Low-protein diet slows Alzheimer's in mice

Mice with many of the pathologies of Alzheimer's Disease showed fewer signs of the disease when given a protein-restricted diet supplemented with specific amino acids every other week for four months. Mice at advanced stages of the disease were put on the new diet. They showed improved cognitive abilities over their non-dieting peers when their memory was tested using mazes. In addition, fewer of their neurons contained abnormal levels of a damaged protein, called "tau," which accumulates in the brains of Alzheimer's patients.

Upcoming studies [will] attempt to determine whether humans respond similarly - while simultaneously examining the effects of dietary restrictions on cancer, diabetes and cardiac disease. "We had previously shown that humans deficient in Growth Hormone receptor and IGF-I displayed reduced incidence of cancer and diabetes. Although the new study is in mice, it raises the possibility that low protein intake and low IGF-I may also protect from age-dependent neurodegeneration."

The team found that a protein-restricted diet reduced levels of IGF-1 circulating through the body by 30 to 70 percent, and caused an eight-fold increase in a protein that blocks IGF-1's effects by binding to it. IGF-1 helps the body grow during youth but is also associated with several diseases later in life in both mice and humans. Exploring dietary solutions to those diseases as opposed to generating pharmaceuticals to manipulate IGF-1 directly allows Longo's team to make strides that could help sufferers today or in the next few years.

"We always try to do things for people who have the problem now. Developing a drug can take 15 years of trials and a billion dollars. Although only clinical trials can determine whether the protein-restricted diet is effective and safe in humans with cognitive impairment, a doctor could read this study today and, if his or her patient did not have any other viable options, could consider introducing the protein restriction cycles in the treatment - understanding that effective interventions in mice may not translate into effective human therapies."

You might take note of those last remarks as indicative of one of the ways in which regulation steers researchers towards deliberately aiming to produce marginal benefits rather than revolutionary advances - slowing the pace of progress and shutting down promising avenues of medical science before they even get started.

Nitric Oxide and Longevity in Nematodes

Nitric oxide shows up in many places in the the biochemistry of longevity, the processes by which differences in the operation of metabolism influence the pace of aging. In this example, however, it isn't particularly clear that it has any great relevance to human biology:

Although humans and many other organisms have the enzyme needed to produce nitric oxide, C. elegans does not. Instead, [the] worm can "hijack" the compound from the soil-dwelling Bacillus subtilis bacterium that is not only a favored food but also a common colonist within its gut. This resourcefulness [partially] explains why worms fed B. subtilis live roughly 50 percent longer than counterparts fed Escherichia coli, which does not produce the compound.

In the new study, the average C. elegans lifespan increased by nearly 15 percent, to about two weeks, when researchers fed the worms nitric oxide-producing B. subtilis bacteria, compared to worms fed mutant B. subtilis with a deleted nitric oxide production gene. The research group also used fluorescent sensors to show that C. elegans does not make its own nitric oxide gas. When the worms were fed normal B. subtilis bacteria, however, the fluorescent signal appeared in their guts.

Fluorescent labeling and other tests also demonstrated that B. subtilis-derived nitric oxide penetrated the worms' tissues, where it activated a set of 65 genes. Some had been previously implicated in stress resistance, immune response, and increased lifespan, though others have unknown functions. Importantly, the researchers showed that two well-known regulatory proteins were essential for activating all of the genes.

"What we found is that nitric oxide gas produced in bacteria inside the worms diffuses into the worm tissue and activates a very specific set of genes acting through two master regulators, hsf-1 and daf-16, resulting in a high resistance to stress and a longer life. It's striking that a small molecule produced by one organism can dramatically affect the physiology and even lifespan of another organism through direct cell signaling."

On Greater Longevity in Colder Environments

Why do cold-blooded species live longer in colder environments? Researchers have a prospective mechanism that is shared by mammals:

Scientists have known for nearly a century that cold-blooded animals, such as worms, flies and fish all live longer in cold environments, but have not known exactly why. Researchers [have] identified a genetic program that promotes longevity of roundworms in cold environments - and this genetic program also exists in warm-blooded animals, including humans. "This raises the intriguing possibility that exposure to cold air - or pharmacological stimulation of the cold-sensitive genetic program - may promote longevity in mammals."

Scientists had long assumed that animals live longer in cold environments because of a passive thermodynamic process, reasoning that low temperatures reduce the rate of chemical reactions and thereby slow the rate of aging. "But now, at least in roundworms, the extended lifespan observed at low temperature cannot be simply explained by a reduced rate of chemical reactions. It's, in fact, an active process that is regulated by genes."

[Researchers] found that cold air activates a receptor known as the TRPA1 channel, found in nerve and fat cells in nematodes, and TRPA1 then passes calcium into cells. The resulting chain of signaling ultimately reaches DAF-16/FOXO, a gene associated with longevity. Mutant worms that lacked TRPA1 had shorter life spans at lower temperatures.

Because the mechanisms [also] exist in a range of other organisms, including humans, the research suggests that a similar effect might be possible. The study also links calcium signaling to longevity for the first time and makes a novel connection between fat tissue and temperature response. Researchers have known that lowering the core body temperature of warm-blooded animals, such as mice, by 0.9 degrees Fahrenheit can extend lifespan by 20 percent, but it hasn't been practical for humans to attempt to lower the core body temperature.

It's worth noting that past research has shown that not all methods of lowering core body temperature in mammals will extend life. It matters how it's done, which suggests that it isn't so much temperature as the particular mechanisms that are running that is driving the effect. For example, calorie restriction is associated with a lower core body temperature.

Are You an Ambitious Life Science Student? Intern at the SENS Research Foundation this Summer

Here is a great opportunity for undergraduate and recently graduated life scientists: a chance to intern this coming summer at the SENS Research Foundation, an ambitious and well-connected organization that funds work on repairing the cellular and molecular damage that causes aging. If this is an area of applied medical biotechnology that interests you - and it should, as today you stand at the ground floor of a field that will expand in decades ahead to dwarf present behemoth research communities like the cancer establishment - then I encourage you to apply. If this isn't your cup of tea, then point it out to any biologist friends you might have.

2013 Summer Internships at the SENS Research Foundation

SENS Research Foundation's summer internships are for undergraduates (students working towards a Bachelor's degree) and students who have just completed their undergraduate work. Interns in this program can expect to do a considerable amount of scientific research using various techniques in the biosciences, which can include PCR, western blotting, DNA purification, gel electrophoresis, and many others. Each intern will be working on a different project, so no two will be doing the exact same thing. Though interns will build their lab skills considerably during their internship period, the strongest applicants will already have laboratory experience.

In 2013, SENS Research Foundation will be placing summer interns at four different locations: SRF's own Research Center in Mountain View, California; the Buck Institute for Research on Aging in Novato, California; the Wake Forest Institute for Regenerative Medicine in Winston-Salem, North Carolina; and SUNY Upstate Medical University in Syracuse, New York. You will be able to apply to all four of these locations at the same time using our application. Note that the SRF Research Center and the Buck Institute are in the same metropolitan area: the San Francisco Bay Area.

The application deadline for our summer internship program is March 31, 2013 at 11:00 PM PST. However, there will be an early deadline for applicants who would like to be considered for the SUNY Upstate program: February 24th, 2013 at 11:00 PM PST. Each program will run on its own schedule, with its own stipend and arrangements.

Connections make the world go round, and certainly do wonders for your future career in a field. This is a chance to make important connections in the longevity science community, working in laboratories run by leaders in the field, and at the same time start to do your part to advance the state of rejuvenation biotechnology. You might take a look at the SENS Research Foundation's annual reports for an in-depth look at the ongoing work that takes place in their research center and partner laboratories in the US and Europe.

Searching for Commonalities in Cancer

The broad variety and rapid change in mechanisms within cancerous cells is one of the reasons that cancer is hard to tackle - every cancer is different and evolving. Circumventing this to find truly effective cancer therapies will require the discovery of some mechanistic commonality that can be targeted, some biological process that all cancers depend on and which distinguishes their cells from non-cancerous cells. The proposed SENS approach, for example, is to go right to the root and remove all ability to lengthen telomeres in the body, as all cancers depend on that. The mainstream research community aims to find markers for cancer stem cells, or low-level mechanisms shared between cancers to some degree and which can be sabotaged to slow down or reverse progression of the disease. Not all shared mechanisms are sufficient to build a true cure, unfortunately.

Here is an example of one such lesser mechanism in the early stages of research and development:

Epithelial to mesenchymal transition is important to embryonic development, turning stationary epithelial cells into mobile mesenchymal cells to move them within the embryo. For example, a cell might be converted and then gather with other cells forming, for example, the kidney. Once there, it transitions back to an epithelial cell again and stays put. Research has shown that carcinomas, tumors that form in the epithelium (lining) of organs are able to reactivate EMT. About 85 percent of all solid tumors are carcinomas.

"We found that FOXC2 lies at the crossroads of the cellular properties of cancer stem cells and cells that have undergone epithelial to mesenchymal transition (EMT), a process of cellular change associated with generating cancer stem cells. There are multiple molecular pathways that activate EMT. We found many of these pathways also activate FOXC2 expression to launch this transition, making FOXC2 a potentially efficient check point to block EMT from occurring."

[Researchers believe] that targeting FOXC2 pathway [will] be an effective therapeutic strategy for inhibiting EMT and consequently reducing EMT/cancer stem cell-associated metastasis, relapse and therapy resistance.

Truncated dystrophins reduce muscle stiffness in the extensor digitorum longus muscle of mdx mice

Muscle stiffness is a major clinical feature in Duchenne muscular dystrophy (DMD). DMD is the most common lethal inherited muscle-wasting disease in boys, and it is caused by the lack of the dystrophin protein. We recently showed that the extensor digitorum longus (EDL) muscle of mdx mice (a DMD mouse model) exhibits disease-associated muscle stiffness. Truncated micro- and mini-dystrophins are the leading candidates for DMD gene therapy. Unfortunately, it has never been clear whether these truncated genes can mitigate muscle stiffness. To address this question, we examined the passive properties of the EDL muscle in transgenic mdx mice that expressed a representative mini- or micro-gene (H2-R15, R2-15/R18-23/C, or R4-23/C). The passive properties were measured at the ages of 6 and 20 mo a...

Be Mine Forever: Oxytocin May Help Build Long-Lasting Love

If cupid had studied neuroscience, he’d know to aim his arrows at the brain rather than the heart. Recent research suggests that for love to last, it’s best he dip those arrows in oxytocin. Although scientists have long known that this hormone is essential for monogamous rodents to stay true to their mates, and that it makes humans more trusting toward one another, they are now finding that it is also crucial to how we form and maintain romantic relationships.

San Jose Newspaper Lauds CIRM Chairman Thomas

The California stem cell agency got some good
news this week. The San Jose Mercury News ran an editorial yesterday
that was headlined,

“State stem cell agency is
taking Institutes of Medicine advice”
The 306-word editorial said CIRM
Chairman Jonathan Thomas is a refreshing change from Robert Klein,
the first chairman of the $3 billion enterprise. The brief editorial
said Thomas recognizes that the eight-year-old agency "has to mature." It said Thomas was trying to improve transparency and accountability.
The last paragraph declared,
 “If the stem cell agency can establish a record
as a good steward of public dollars to finance brilliant
science, it can continue to play a useful role in
stimulating and guiding research to bring the potential
cures from stem cell research to fruition.”

No Improper Influence: CIRM Defends ‘No Actual Conflicts’ Claim

Earlier
this month the California Stem Cell Report  published an item that said:

“In
the wake of recent considerable criticism concerning conflicts of
interest at the $3 billion California stem cell agency, its leaders
have taken to saying 'no actual conflicts' have been found at the
agency.

“That
assertion is simply not true.”

We
asked the stem cell agency if it would like to respond and said that
its response would be carried verbatim. The agency's comments are below. Our
take on the response follows the CIRM comments, which were authored
by Kevin McCormack, the agency's senior director for public
communications and patient advocate outreach.

In
David Jensen’s recent blog about the stem cell agency he claims to
“debunk” claims that there have been no actual conflicts in
CIRM’s funding decisions saying “the agency has a long history of
problems involving conflicts of interest, 'actual' and otherwise.”
In fact, in the cases cited by Mr. Jensen, show 'otherwise' is the
appropriate word here because as we’ll show CIRM’s conflict
procedures worked and the funding decisions were not affected by any
improper influence.
Let’s
take it case by case, looking at each instance of a “conflict”
cited by Mr. Jensen.
John
Reed
In
2007, John Reed, a member of the stem cell agency’s Governing
Board, contacted staff in his capacity as the president of the
Burnham Institute after the Board approved a SEED grant award to a
Burnham investigator. Dr. Reed did not participate in the Board’s
decision to approve the award and played no role in that decision.
All he did was send a letter to CIRM staff after the Board meeting to
provide factual information in response to technical questions raised
by CIRM staff concerning the investigator’s eligibility for an
award. Those questions ultimately led staff to reject the grant.
Because the Board had already made the decision to award the grant,
it did not occur to Dr. Reed that the conflict rules would prevent
him from contacting staff to provide relevant information. And why
would it? The decision was made so there was nothing to influence.
After CIRM staff received Dr. Reed’s letter, they informed Dr. Reed
that he must refrain from participating in any way in CIRM's
consideration of the Burnham grant. In addition, CIRM staff did not
consider the letter in conducting their administrative review of the
Burnham grant and their determination that the investigator was not
eligible did not change. The FPPC determined that, although Dr.
Reed’s conduct raised ethical concerns, he had not violated
conflict of interest laws because he attempted to influence a
decision that had already been made. Furthermore, Dr. Reed’s
conduct did not affect a CIRM funding decision because the grant was
rejected by CIRM staff.
New
Faculty Awards
When
a candidate applies for a CIRM New Faculty Award it is standard
practice for them to include a letter of support from the institution
where they hope to be working. In December 2007, during a review of
applications for New Faculty Awards, CIRM staff discovered that ten
applications were accompanied by letters of institutional support
signed by members of the Board. This was due to a miscommunication by
staff, a poorly drafted memo to Board members leading them to think
it was OK to sign the letters of institutional support. The error was
discovered before the Board considered any of the applications. CIRM
staff determined that the letters could be perceived to create a
conflict of interest and so, to avoid even the appearance of a
conflict, CIRM staff disqualified the ten applications. As a result,
the applications were not presented to the Board for its
consideration, thereby avoiding any potential for a conflict of
interest in a funding decision.
John
Sladek
In
2011, while preparing the public summary for Basic Biology III
applications, CIRM staff discovered that Dr. John Sladek was one of
several co-authors on scientific publications with a researcher who
was listed as a consultant on a CIRM grant application. This is a
technical violation of the Grants Working Group (“GWG”) conflict
policy, which prohibits a member of the GWG from participating in the
review of an application if the member has co-authored papers with a
salaried investigator listed on a CIRM application within a three
year window. It should be noted, however, that Dr. Sladek’s
participation in the review of the application would not have
constituted a conflict of interest under state conflict of interest
laws because Dr. Sladek did not have a financial interest in the
application. In addition, the amount of funding involved –
approximately $3,000 of salary per year for three years, less than
one percent of the total award – was not material, and Dr. Sladek
did not stand to receive any financial benefit from the application.
Finally, Dr. Sladek’s participation in the review did not affect
the outcome because the application was not recommended, or approved,
for funding.
The
three instances cited by Mr. Jensen share two common features.
First, CIRM staff identified the potential for a conflict before any
funding decision was made. Second, CIRM’s funding decisions were
not affected by any improper influence.
Ted
Love
Mr.
Jensen also cites the service of Dr. Ted Love, a member of the Board
who volunteered his time to assist CIRM in offering his scientific
and medical expertise, as evidence of a conflict of interest.
Although Mr. Jensen insinuates that Dr. Love’s service constituted
a conflict of interest, he does not cite any facts, except Dr. Love’s
“deep connections to the biomedical industry.” But the fact that
Dr. Love has experience in the biotech industry does not constitute a
conflict of interest, and as a member of the Board and as a volunteer
to CIRM, Dr. Love abided by CIRM’s conflict of interest policies.
In
the past Mr. Jensen has criticized the stem cell agency for its lack
of connections and engagement with industry. In this case he
criticizes us precisely because of our connection and engagement with
someone who has industry experience.
Venture
Capital Firm
Mr.
Jensen also suggests that a conflict of interest arose from the fact
that “iPierian,Inc., whose major investors [a venture capital firm]
contributed nearly $6 million to the ballot measure that created the
stem cell agency, has received $7.1 million in awards from the
agency.” While it is true that Proposition 71 involved a
multi-million dollar campaign, the funding for the campaign came
primarily from individuals who had a family member who suffered from
a chronic disease or injury, including individuals associated with a
venture capital firm. The firm itself did not contribute to the
campaign, nor did the campaign accept contributions from
biotechnology or pharmaceutical companies. Furthermore, the venture
capital firm did not invest in a CIRM grantee; rather, it invested in
a different company which subsequently merged with yet another
company to form an entity that later applied for, and was awarded a
CIRM grant.
Stem
Cells, Inc.
Mr.
Jensen cites CIRM’s award to Stem Cells, Inc. as another source of
a conflict. In support of this claim, Mr. Jensen’s references Bob
Klein’s support of the award, as well as the fact that Irv
Weissman, PhD, appeared in an ad for Proposition 71 in 2004.
However, neither Mr. Klein’s support for the award nor Dr.
Weissman’s support for Proposition 71 constitutes a conflict of
interest. First, Mr. Klein, like any member of the public, has the
right to express his views to the Board. The state’s revolving
door laws do not apply to a former member of the Board who, like Mr.
Klein, is not compensated for making an appearance. As for Dr.
Weissman’s support for Proposition 71, nothing in state law
prohibits a member of the public from seeking CIRM funding even
though he supported the measure during the campaign. In fact, it
would be reasonable to expect that most stem cell scientists in
California (and elsewhere) supported Proposition 71. Disqualifying
individuals from receiving funding because they supported the law
would leave few, if any, eligible applicants.
Allegation
of Conflict at Board Meeting
As
further evidence of an “actual conflict”, Mr. Jensen cites
another instance in 2008 in which a representative of a for-profit
applicant publicly complained at a Board meeting that a member of the
GWG had a conflict of interest “from a business perspective.” As
provided for by CIRM’s regulations, the applicant had filed an
appeal, claiming that the reviewer had a conflict of interest because
he had a financial relationship with another company that was not an
applicant for CIRM funding. CIRM’s legal counsel reviewed the
appeal and determined that there was no conflict of interest under
CIRM’s policy.
Saira
Ramasastry and Laurence Elias
Mr.
Jensen cites two instances in which CIRM’s hired consultants in
support of his claim that CIRM has “actual conflicts of interest.”
In 2010, CIRM retained a partner at Life Sciences Advisory, LLC,
Saira Ramasastry, to assist CIRM’s External Advisory Panel, which
completed its work in December 2010. In 2012, Sangamo BioSciences,
Inc., nominated Ms. Ramasastry to serve on its Board of Directors.
Although Ms. Ramasastry continued to provide some consulting services
to CIRM through fiscal year 2011-12, none of her work for CIRM
involved Sangamo or any CIRM program in which it was involved. Ms.
Ramasastry’s services on behalf of CIRM did not create any conflict
of interest. The same is true of the second instance cited by Mr.
Jensen. In 2010, CIRM hired Dr. Laurence Elias, a former Geron
employee and an accomplished clinical development professional, to
provide CIRM with technical and regulatory input to ensure that the
clinical elements of an RFA were technically complete and accurate.
The concept for RFA had already been approved and as such Dr. Elias
was not in any position to influence the overall scope or structure,
nor did he have any role in evaluating applications. CIRM staff and
Dr. Elias complied with all conflict of interest requirements.
Neither contract led to an “actual conflict of interest”.
Diane
Winokur
Mr.
Jensen’s laundry list of “conflicts” also includes a reference
to the recent appointment of Diane Winokur to serve on CIRM’s
Board. Mr. Jensen quotes a representative of the ALS Association who
said that Ms. Winokur will be “a tremendous asset in moving the ALS
research field forward through CIRM funding." Of all the
insinuations made in his blog this is perhaps the cheapest shot,
taking aim at a woman who has dedicated her life to fighting a deadly
disease, one that claimed the lives of her two sons. Mr. Jensen knows
very well that the ALS Association does not speak for Ms. Winokur or
CIRM and while we expect that Ms. Winokur will bring her expertise as
an advocate for people suffering from ALS to the Board, she, like all
members of CIRM’s Board, represents all Californians, not just
those suffering from a particular disease. Ms. Winokur’s
appointment does not create a conflict of interest.
Press
Releases
Finally,
Mr. Jensen cites a Board debate from 2006 involving a requirement in
CIRM’s intellectual property regulations regarding press releases.
Under Health and Safety Code section 125290.30(g)(1)(C), the
discussion of standards does not create a conflict of interest, and
the Board’s debate was enriched by the participation of members who
brought their expertise and experience to bear.
Mr.
Jensen says that one of the reasons why the IOM did not report any
instances of conflict of interest in its report is that it did not
look for any conflicts of “inappropriate behavior,” But Mr.
Jensen was present in the public hearing at UC Irvine in April of
2012 when the IOM panel asked Stuart Drown, Executive Director of the
Little Hoover Commission that also looked into allegations of
conflict of interest at CIRM, if he could cite any actual instances.
Mr. Drown said he could not. Nor did Mr. Jensen offer any when it was
his turn to talk.



The view from the California Stem Cell Report:
Generally
speaking, CIRM's response about “actual” conflicts of interests
is a reiteration of what the California Stem Cell Report carried at
the time of each incident and does not add much new to the discussion
of the issues. All of the agency's earlier responses could be found in
the links in the “debunking” piece. Additionally the agency
confuses what are clearly actual conflicts with other instances that
could involve either actual or perceived conflicts, which the IOM
noted can be as deadly as the real thing. However,
in the most egregious cases involving Reed and later the five medical
school deans, the agency would like the public to believe that these
were not serious matters because the staff detected and caught the
conflicts before the grants were made.
That
is like saying a burglar who was caught in the act before he escaped
with his booty committed no offense.
The
acts were committed by members of the CIRM board, and they were
violations of conflict of interest standards. In the case of
the five deans, that is why the agency voided 10 applications
totaling $31 million from their five institutions. If there had been
no actual conflict of interest, that would not have been necessary.
As
for blaming the staff for “miscommunications,” the applications
that the five deans signed were quite clear and offered them the
option of having another person at their institution sign the grant
proposal. Other deans on the board did not sign applications in the
same round. Those applications were then handled in the normal
fashion. One might ask how in the world could the head of a medical
school who was also serving on the CIRM board NOT recognize a
conflict of interest when asked to sign a request for cash from the
board on which he served?
Regarding
John Reed and his conflict of interest violation, both he and then
CIRM Chairman Robert Klein have acknowledged Reed's actions
were wrong. Klein, an attorney who directed the writing of the
10,000-word measure that created CIRM, advised Reed to contact CIRM
staff to lobby on behalf of a grant that was approved by the board
but was about to be denied by staff.(See here, here and here.)
CIRM's
response contends that Reed's 6 ½ page letter was nothing more than
“factual” information dealing with technical matters. That is
hardly the case. In fact, Reed explicitly “emphasized” (Reed's word) that failing to comply with his letter would damage the future
of the stem cell agency. Denial of the grant, he said, “will surely
discourage clinical researchers from participating in the CIRM
mission to advance stem cell therapies.”   
Reed's
action was inappropriate, and the California Fair Political
Practices Commission warned Reed about his actions. The journal Nature reported,

“California’s
Fair Political Practices Commission (FPCC) decided that Burnham
Institute
President violated conflict-of-interest rules by writing a
letter to the California Institute of Regenerative Medicine appealing
a decision that an affiliate of his institute was ineligible for
funding.”

The
California Stem Cell Report's “debunking” piece went beyond "actual" conflicts to describe other instances where conflicts emerged.
Readers can go back to the original links for all the details, but
the cases of StemCells, Inc., and iPierian, Inc., are worth reviewing
again. Both cases involve fund-raising efforts that ran into
millions of dollars for the ballot measure campaign that created
CIRM. The campaign was run by Bob Klein who later became the agency's
first chairman, serving for six years and becoming something of a
hallowed figure in stem cell circles. One of the principal jobs of a
campaign manager is to raise the millions needed to run a successful
statewide election campaign in California. It is common for members
of the public to believe that major campaign contributors are
rewarded later for their contributions. Whether that was the case in
these instances, the reader must decide for himself or herself. But
the appearance is less than salubrious for an agency that claims to
have never seen an actual conflict of interest as it has handed out
$32,000 an hour, 24 hours a day, seven days a week during the last six
years.
The
facts are that about 90 percent of the $1.7 billion awarded by the
CIRM board has gone to institutions tied to present and past members
of its governing board. The agency, however, does work hard to be
sure legal conflicts do not arise during board action on grant
applications, using a voting procedure that is so convoluted that the
actual vote on nearly all applications is not even announced at board
meetings. Sometimes the procedure means that only a handful of
governing board members can participate in debate or vote. In the
case of the five medical school deans, as the board struggled to deal
with the fallout in 2007, only eight of the 29 members of the board could participate in the discussion because the rest had conflicts.
As
for CIRM's comments about “insinuations” and “cheap shots” by
the California Stem Cell Report, we naturally differ with that
characterization. The case in point involved what the chief scientist
for a patient advocate group said she expected as the result of a
recent appointment to the board. The scientist's remarks were offered
as example of the type of expectation and entitlement that can arise when governing
board members must be picked from specific constituencies, as is the
case with all 29 CIRM board members.



And as for my testimony at the IOM hearing last April, here is a link to my statement, which includes a discussion of conflicts of interest.

CIRM Board Member Prieto Critiques the IOM Stem Cell Report

Francisco Prieto, a member of the
governing board of the $3 billion California stem cell agency, is
expressing some additional dissatisfaction with the blue-ribbon
Institute of Medicine (IOM) report for which the agency paid $700,000.

The report recommended sweeping changes
at the agency, including creation of a new majority of independent
members on the board. The IOM cited problems arising from the
built-in conflicts of interest on the board that were created by
Proposition 71, which created in the agency in 2004. Prieto's email refers to Bob Klein, who is a real estate investor and attorney. Klein
oversaw the drafting of the 10,000-word ballot measure(writing much
of it himself), ran its $35 million ballot campaign and became the
first chairman of the agency. The qualifications for chairman were written into the proposition and seemed to uniquely apply to Klein.  Prieto is a Sacramento physician who
was appointed to the board as patient advocate.
.Here is the text of Prieto's comments.
His earlier comments can be found here.

“A few more words on independence,
and the IOM.  I think Bob Klein drafted the proposition (and
remember, all of this was spelled out there – readily available to
the voters and whatever news sources they were depending on for
information) deliberately to engage patient advocates. I think  he
knew that those of us who have been active in disease advocacy have a
passion around the issue of advancing research that someone without
that background would be unlikely to have. I’m not sure exactly
what the IOM had in mind when they called for more 'independent'
members of the board, since they very unfortunately did not bother to
interview the patient advocates on the ICOC(the governing board). I
don’t know what their reason for this was, if there was one, but
they only circulated a (in my view) frankly inadequate questionnaire,
and interviewed a small handful of people. I think this was a major
flaw in their process and gave them a very limited view of our role.
It is hard for me to imagine who they might have in mind, if not
people who had been involved with some existing advocacy
organization. I think there are very few if any patient advocates who
aren’t working with some group – the only ones I might imagine
would be some independently wealthy person able to start a foundation
or research institute on their own.  With all due respect to
Bill Gates and the great work his foundation is doing with malaria
and HIV, I have written before that I think it would be absolutely
wrong and anti-democratic to create any public board or commission
that only millionaires could sit on.”

An anonymous comment was also posted
concerning the IOM report and conflicts of interest. It dealt briefly
with the issue and difficulty of managing conflicts. The comment can be found at the end of this item.

Parkinson's Disease as Localized Garbage Catastrophe

Alpha-synuclein is associated with Parkinson's disease (PD), and is believed to play a central role in the mechanisms that cause the destruction of dopamine-generating neurons, and thus the pathology of the condition. Here, researchers dig deeper into the processes involved:

Overexpression of a protein called alpha-synuclein appears to disrupt vital recycling processes in neurons, starting with the terminal extensions of neurons and working its way back to the cells' center, with the potential consequence of progressive degeneration and eventual cell death. "This is an important new insight. I don't think anybody realized just how big a role alpha-synuclein played in managing the retrieval of worn-out proteins from synapses and the role of alterations in this process in development of PD."

Using a variety of leading-edge imaging technologies, including a new fluorescent tagging technique developed for electron microscopy, [the] scientists created three-dimensional maps of alpha-synuclein distribution both in cultured neurons and in the neurons of mice engineered to over-express the human protein. They found that excess levels of alpha-synuclein accumulated in the presynaptic terminal - part of the junction where axons and dendrites of brain cells meet to exchange chemical signals.

"The over-expression of alpha-synuclein caused hypertrophy in these terminals. The terminals were enlarged, filled with structures we normally don't see." [As] alpha-synuclein accumulates in the terminals, it appears to hinder normal degradation and recycling processes in neurons. This would progressively impair the release of neurotransmitters. In time, the neurons might simply stop functioning and die.

Stem Cell Agency Board Member Defends Independence of Many on Board

A member of the governing board of the
California stem cell agency is taking exception to a statement on the
California Stem Cell Report that no independent members sit on that
body.

Francisco Prieto, a Sacramento
physician and a patient advocate member of the board, referred to the
“ethical minefield” item Feb. 5, 2013. Here is the text of what
Prieto wrote,

“I have to object to this line: 'None
of the current members are independent. The ballot measure that
created the agency required board members to be appointed from
various constituencies.' 

“I think I am absolutely independent,
and I think the same applies at the very least to most if not all of
my fellow patient advocates, and probably to the biotech
representatives as well – remember that they all must come from
companies that are not involved in stem cell research.  Although
I supported the proposition, I was not involved directly in the
campaign in any way, and I did not meet Bob Klein (the first chairman of the stem cell board) or any of my fellow
board members until the day I was sworn in at our first meeting.

“The Prop. 71 language I believe
specifies that advocates must have a record of advocating for people
with the disease or diseases they represent, and not that they belong
to or work for any specific organization.  Checking my binder,
it refers to 'groups' but does not specify those – for example, it
refers to 'representative of a California regional, state or national
HIV/AIDS disease advocacy group.' I’m not sure how you would
define 'independent' but I certainly don’t think it means
'disinterested.'”

Our take: The Institute of Medicine(IOM) called for a new majority of what it described as independent
members, obviously not finding sufficient, if any, independent
members on the agency board. The IOM, the most prestigious organization of
its kind in the country, said changes were needed because of damaging
conflict of interest issues at the stem cell agency.
Prop. 71, which created the stem cell
agency in 2004, was carefully crafted to avoid the use of the word
“independent” when describing the necessary qualifications for a
board member.
 Instead the measure required that, in some cases, they
must come from very specific education institutions. (You can find the CIRM summary of all qualifications within this document.) In other cases, the speaker of the
state Assembly appoints “one representative of a California
regional, state, or national mental health disease advocacy group.”
The leader of the state Senate appoints “one representative of a
California regional, state, or national HIV/AIDS disease advocacy
group. “ Four other statewide elected officials appoint an
executive from a “California life science commercial entity.”
Prieto is correct when he says he
believes he is “absolutely independent.” But he fills a category
that represents a special constituency. What is missing from the
board is anyone who does not come from one special constituency or
another. The board was constructed in that manner to make sure it
would win the broadest measure of support from all the various major
constituencies by guaranteeing them a seat at the table where the
money is handed out.  Ironically, the full formal name of the CIRM governing board is the "Independent Citizens Oversight Committee," a piece of political legerdemain to mask the actual nature of who would sit on the board.

Riverside Newspaper: 'Ethical Minefield' Still Not Cleared at Stem Cell Agency

The California stem cell agency's
attempts to deal with the conflict of interest problems at the $3
billion research program amount to a minor fix that is not a “serious solution,” the Riverside Press-Enterprise editorialized yesterday.

The editorial came as the agency
launches a road trip campaign to convince newspaper editorial boards around
the state that the agency is worthy of continued financial support.
The agency will run out of money for new grants in less than four
years.
The Riverside editorial pointed to the blue-ribbon Institute of Medicine report in December that called for creation of a
new, independent majority on the 29-member board. None of the current
members are independent. The ballot measure that created the
agency required board members to be appointed from various
constituencies.
The newspaper said,

“That arrangement is hardly a model
of objective decision making. The agency so far has distributed about
$1.7 billion in grants, with about 90 percent of that money going to
institutions represented on the governing board. 

“Voluntary abstentions are not a
serious solution to that ethical minefield. Nor would that approach
eliminate potential conflicts, because the agency would still allow
the abstaining members to take part in the discussions and debate
about who should get the grants. 

“The Institute of Medicine instead
recommended remaking the board with truly independent members who
have no stake in grant awards. The stem-cell agency rejected that
step because it would require changing Prop. 71, either through a
super-majority in the Legislature or another ballot measure. That
excuse should be a vivid warning to Californians about the dangers of
passing complex, costly and inflexible initiatives. 

“Agencies handling billions of
taxpayers’ dollars should not avoid good government practice or
basic fiscal safeguards. The stem-cell institute offers minor fixes
when it needs substantial changes — and legislators should not
accept that cavalier approach.”

Debunking California Stem Cell Agency Claims of ‘No Actual Conflicts’

In the wake of recent considerable
criticism concerning conflicts of interest at the $3 billion California stem
cell agency, its leaders have taken to saying “no actual conflicts”
have been found at the agency.

That assertion is simply not true.
Nonetheless, the statement has been
repeated in some news stories, published in at least one agency press
release and peddled by stem cell advocates and some members of the
governing board of the California Institute for Regenerative Medicine
(CIRM)
, as the agency is formally known.
The reason? Conflicts of interest were
cited prominently as a major problem at CIRM by the blue-ribbon
Institute of Medicine (IOM) report. In December, the IOM recommended that a new majority of independent members be created on the stem
cell agency's governing board. The existing stem cell board has
ignored that recommendation and wants to settle for something considerably less as it tries to find a way to build support for
continued financing of its efforts.
The facts are that the agency has a
long history of problems involving conflicts of interest, “actual”
and otherwise. Here is a rundown on what has been reported on the
California Stem Cell Report.
In 2009, board member John Reed, then
CEO of the Sanford-Burnham Institute, was warned by the state's Fair Political Practices Commission about his violation of conflict of interest rules. Reed's intervention on behalf of a grant was made at the suggestion of then CIRM Chairman Robert Klein, an attorney who
led the drafting of Proposition 71, the ballot initiative that created the stem cell
agency in 2004.
In 2007, other violations involving five board members resulted in voiding applications from 10
researchers seeking $31 million. And then the agency shamefully scapegoated employees for the problem.
In 2011, the chairman of the CIRM grant review group resigned from his position as the result of another
violation, which the agency felt necessary to report to the
California legislature.
In 2009, then board member Ted Love,
who has deep connections to the biomedical industry, served as the
agency's interim chief scientific officer and helped to develop the agency's first, signature $225 million disease team round while also
serving on the CIRM board. As chief scientific officer, Love
presumably would have had access to proprietary information and trade
secrets contained in grant applications. In 2009, in response to
questions from the California Stem Cell Report, the agency said that Love would only serve as a part-time adviser to the agency president, not as chief scientific officer. Nonetheless, in 2012, the board
passed a resolution with high praise for Love and his performance as the chief scientific officer.
Since 2010, a stem cell firm, iPierian,Inc., whose major investors contributed nearly $6 million to the ballot measure that created the stem cell agency, has received $7.1
million in awards from the agency. The contributions were 25 percent
of the total in the campaign, which was headed by Klein.
Another firm, StemCells, Inc., last
fall was awarded $40 million by the CIRM board despite having one of
its $20 million applications rejected twice by grant reviewers. The
action came after the board was vigorously lobbied by former Chairman
Klein. Researcher Irv Weissman of Stanford, who founded StemCells, Inc., and
is on its board, was featured in a TV campaign ad for Proposition 71 and helped to raise millions for the ballot campaign. 
In 2008, public complaints by one
applicant from industry about conflicts of interest on the part of a
reviewer were brushed off by Klein. He told the applicant the board needed to discuss naming CIRM-funded labs and then go to lunch. 
The agency has hired at least two
industry consultants in positions that raise conflict of interest
problems, in 2010 and again in 2012.
Sometimes groups expect to see
increased funding as the result of the appointment of sympathetic
individuals to the board. That occurred last fall when Diane Winokur
was appointed. The chief scientist for The ALS Association, said
Winokur will be “a tremendous asset in moving the ALS research field forward through CIRM funding."
The conflict issue even surfaces in picayune ways. In 2006, board members from various institutions spent
considerable time debating a minor requirement involving press
releases. They were concerned that the proposal would make their
institutions subordinate to the interests of CIRM. At the end of the
discussion, the institutional directors prevailed and kept their PR
departments from having to notify CIRM about press releases dealing
with the hundreds of millions of dollars in state grants that they
receive.
All this, and yet on Jan. 24, 2013,
CIRM Chairman Jonathan Thomas was quoted in a CIRM press release as
saying “no one has found any actual conflicts” at the
agency.
In the media, some of the recent news
stories have reported that the IOM did not find any “actual”
conflicts at the agency. The explanation for that is simple, but
mainly omitted from the articles. The IOM did not look for any
conflicts of “inappropriate behavior,” as its report clearly
states. The California Stem Cell Report last weekend asked the
chairman of the IOM panel, Harold Shapiro, why it did not look for
conflicts. He replied,

“Our committee was given a set of
defined tasks from the IOM(which was under a $700,000 contract with
CIRM), and we followed them."

Nonetheless, the IOM report said “far
too many” board members are linked to institutions that receive
funds from CIRM. A compilation by the California Stem Cell Report
shows that about 90 percent of the $1.7 billion that the board has
awarded has gone to institutions linked to past and present board
members.
The fundamental conflict problem with
the CIRM board is that nearly all the California institutions that stood to
benefit from the agency's largess were given seats at the table where the
money is handed out, under the terms of Proposition 71.
Conflict problems are not unique to
CIRM and government agencies. They are also a matter of concern at
nonprofit, grant-making foundations, which in some ways CIRM
resembles.
The Council on Foundations, a
national nonprofit association of more than 1,700 grant-making
organizations, takes pains on its web site to explain the
importance of managing and avoiding conflicts of interests. In its advice to its members, the group makes it clear that the issue goes
well beyond simple financial conflicts. It says,

“(Board) members must represent
unconflicted loyalty to the interest of the foundation. This
accountability supersedes any conflicting loyalty such as that to
advocacy or interest groups, business interests, personal interests or paid or volunteer service
to other organizations.”

In the case of the stem cell agency,
the “unconflicted loyalty” is to the people of California. Perhaps the California stem cell agency
can convince state leaders, both public and private, and its voters
that no conflicts exist at the state agency. But it is a big bet and
probably carries with it the entire future of what the board and many
believe is an exceedingly promising scientific effort.
Perhaps it would be wise for the board
to step back and say, “Yes, there are serious conflict problems at
CIRM. We recognize that and are working on additional measures to
create an independent board as recommended by the IOM.”
