Genetic Risk and Stressful Early Infancy Join to Increase Risk for Schizophrenia

- Human genome and mouse studies identify new precise genetic links

Newswise Working with genetically engineered mice and the genomes of thousands of people with schizophrenia, researchers at Johns Hopkins say they now better understand how both nature and nurture can affect ones risks for schizophrenia and abnormal brain development in general.

The researchers reported in the March 2 issue of Cell that defects in a schizophrenia-risk genes and environmental stress right after birth together can lead to abnormal brain development and raise the likelihood of developing schizophrenia by nearly one and half times.

Our study suggests that if people have a single genetic risk factor alone or a traumatic environment in very early childhood alone, they may not develop mental disorders like schizophrenia, says Guo-li Ming, M.D., Ph.D., professor of neurology and member of the Institute for Cell Engineering at the Johns Hopkins University School of Medicine. But the findings also suggest that someone who carries the genetic risk factor and experiences certain kinds of stress early in life may be more likely to develop the disease.

Pinpointing the cause or causes of schizophrenia has been notoriously difficult, owing to the likely interplay of multiple genes and environmental triggers, Ming says. Searching for clues at the molecular level, the Johns Hopkins team focused on the interaction of two factors long implicated in the disease: Disrupted-in-Schizophrenia 1 (DISC1) protein, which is important for brain development, and GABA, a brain chemical needed for normal brain function.

To find how these factors impact brain development and disease susceptibility, the researchers first engineered mice to have reduced levels of DISC1 protein in one type of neuron in the hippocampus, a region of the brain involved in learning, memory and mood regulation. Through a microscope, they saw that newborn mouse brain cells with reduced levels of DISC1 protein had similar sized and shaped neurons as those from mice with normal levels of DISC1 protein. To change the function of the chemical messenger GABA, the researchers engineered the same neurons in mice to have more effective GABA. Those brain cells looked much different than normal neurons, with longer appendages or projections. Newborn mice engineered with both the more effective GABA and reduced levels of DISC1 showed the longest projections, suggesting, Ming said, that defects in both DISC1 and GABA together could change the physiology of developing neurons for the worse.

Meanwhile, other researchers at University of Calgary and at the National Institute of Physiological Sciences in Japan had shown in newborn mice that changes in environment and routine stress can impede GABA from working properly during development. In the next set of experiments, the investigators paired reducing DISC1 levels and stress in mice to see if it could also lead to developmental defects. To stress the mice, the team separated newborns from their mothers for three hours a day for ten days, then examined neurons from the stressed newborns and saw no differences in their size, shape and organization compared with unstressed mice. But when they similarly stressed newborn mice with reduced DISC1 levels, the neurons they saw were larger, more disorganized and had more projections than the unstressed mouse neurons. The projections, in fact, went to the wrong places in the brain.

Next, to see if their results in mice correlated to suspected human schizophrenia risk factors, the researchers compared the genetic sequences of 2,961 schizophrenia patients and healthy people from Scotland, Germany and the United States. Specifically, they determined if specific variations of DNA letters found in two genes, DISC1 and a gene for another protein, NKCC1, which controls the effect of GABA, were more likely to be found in schizophrenia patients than in healthy individuals. They paired 36 DNA letter changes in DISC1 and two DNA letter variations in NKCC1 one DNA letter change per gene in all possible combinations. Results showed that if a persons genome contained one specific combination of single DNA letter changes, then that person is 1.4 times more likely than people without these DNA changes to develop schizophrenia. Having these single DNA letter changes in either one of these genes alone did not increase risk.

Now that we have identified the precise genetic risks, we can rationally search for drugs that correct these defects, says Hongjun Song, Ph.D., co-author, professor of neurology and director of the Stem Cell Program at the Institute for Cell Engineering.

Other authors of the paper from Johns Hopkins are Ju Young Kim, Cindy Y. Liu, Fengyu Zhang, Xin Duan, Zhexing Wen, Juan Song, Kimberly Christian and Daniel R. Weinberger. Emer Feighery, Bai Lu and Joseph H. Callicott from the National Institute of Mental Health, Dan Rujescu of Ludwig-Maximilians-University, and David St Clair of the University of Aberdeen Royal Cornhill Hospital are additional authors.

J. Craig Venter, Ph.D., describes biofuels, vaccines and foods from made-to-order microbes

SAN DIEGO, March 25, 2012 Just as aspiring authors often read hundreds of books before starting their own, scientists are using decades of knowledge garnered from sequencing or "reading" the genetic codes of thousands of living things to now start writing new volumes in the library of life. J. Craig Venter, Ph.D., one of the most renowned of those scientists, described the construction of the first synthetic cell and many new applications of this work today at the 243rd National Meeting & Exposition of the American Chemical Society (ACS), the world's largest scientific society, which is underway this week.

In a plenary talk titled, "From Reading to Writing the Genetic Code," Venter described a fundamental shift in his field of genomics, and its promise for producing synthetic life that could help provide 21st century society with new fuels, medicines, food and nutritional products, supplies of clean water and other resources. Venter, a pioneer in the field, led the team at Celera Genomics that went head-to-head with the government-and-foundation-funded Human Genome Project in the race to decode the human genome. This quest, in which the 23,000 human genes were deciphered, ended with the teams declaring a tie and publishing simultaneous publications in 2001.

"Genomics is a rapidly evolving field and my teams have been leading the way from reading the genetic code deciphering the sequences of genes in microbes, humans, plants and other organisms to writing code and constructing synthetic cells for a variety of uses. We can now construct fully synthetic bacterial cells that have the potential to more efficiently and economically produce vaccines, pharmaceuticals, biofuels, food and other products."

The work Venter described at the ACS session falls within an ambitious new field known as synthetic biology, which draws heavily on chemistry, metabolic engineering, genomics and other traditional scientific disciplines. Synthetic biology emerged from genetic engineering, the now-routine practice of inserting one or two new genes into a crop plant or bacterium. The genes can make tomatoes, for instance, ripen without softening or goad bacteria to produce human insulin for treating diabetes. Synthetic biology, however, involves rearranging genes on a much broader scale that of a genome, which is an organism's entire genetic code to reprogram entire organisms and even design new organisms.

Venter and his team at the not-for-profit J. Craig Venter Institute (JCVI), which has facilities in Rockville, Maryland, and San Diego, announced in 2010 that they had constructed the world's first completely synthetic bacterial cell. Using computer-designed genes made on synthesizer machines from four bottles of chemicals, the scientists arranged those genes into a package, a synthetic chromosome. When inserted into a bacterial cell, the chromosome booted up the cell and was capable of dividing and reproducing.

In the ACS talk, Venter described progress on major projects, including developing new synthetic cells and engineering genomes to produce biofuels, vaccines, clean water, food and other products. That work is ongoing at both JCVI and at his company, Synthetic Genomics Inc. (SGI). A project at SGI for instance, aims to engineer algae cells to capture carbon dioxide and use it as a raw material for producing new fuels. Another group uses synthetic genomic advances with the goal of making influenza vaccines in hours rather than months to better respond to sudden mutations in those viruses.

Venter also described his work in sequencing the first draft human genome in 2001 while he and his team were at Celera Genomics, as well as the work on his complete diploid genome published in 2007 by scientists at JCVI, along with collaborators at The Hospital for Sick Children in Toronto and the University of California, San Diego. In addition to continued analysis of Venter's genome, he and his team are also studying the human microbiome, the billions of bacteria that live in and on people, and how these microbes impact health and disease.

Autism risk gene linked to differences in brain structure

Public release date: 21-Mar-2012 [ | E-mail | Share ]

New Rochelle, NY, March 21, 2012Healthy individuals who carry a gene variation linked to an increased risk of autism have structural differences in their brains that may help explain how the gene affects brain function and increases vulnerability for autism. The results of this innovative brain imaging study are described in an article in the groundbreaking neuroscience journal Brain Connectivity, a bimonthly peer-reviewed publication from Mary Ann Liebert, Inc (http://wwwliebertpub.com). The article is available free online at the Brain Connectivity (http://www.liebertpub.com/brain) website.

"This is one of the first papers demonstrating a linkage between a particular gene variant and changes in brain structure and connectivity in carriers of that gene," says Christopher Pawela, PhD, Co-Editor-in-Chief and Assistant Professor, Medical College of Wisconsin. "This work could lead to the creation of an exciting new line of research investigating the impact of genetics on communication between brain regions."

Although carriers of the common gene variant CNTNAP2identified as an autism risk genemay not develop autism, there is evidence of differences in brain structure that may affect connections and signaling between brain regions. These disruptions in brain connectivity can give rise to functional abnormalities characteristic of neuropsychological disorders such as autism.

###

Emily Dennis and coauthors from UCLA School of Medicine and UCLA (Los Angeles, CA) and University of Queensland and Queensland Institute of Medical Research (Brisbane, Australia), used a sophisticated imaging technique to study the brains of healthy young adults who are carriers of CNTNAP2. They report their findings in "Altered Structural Brain Connectivity in Healthy Carriers of the Autism Risk Gene, CNTNAP2." (http://online.liebertpub.com/doi/abs/10.1089/brain.2011.0064)

Autism risk gene linked to differences in brain structure

Reality check on ‘Hunger Games’ tech

Murray Close / Lionsgate / Everett Collection

Peacekeepers escort Katniss Everdeen (Jennifer Lawrence) in a scene from "The Hunger Games."

By Alan Boyle

The technological divide between the rulers and the ruled is at the heart of "The Hunger Games": While the good guys struggle to survive, the bad guys employ fictional gee-whiz technologies inspired by real-life frontiers. And just as in real life, technology gets tripped up by unintended consequences.

That's not to say the post-apocalyptic North America of the book series and the much-anticipated movie, opening Friday, is anything close to real life. On one level, the technologies used by the villainous government of the nation known as Panem, ranging from force fields to extreme genetic engineering, serve as science-fiction plot devices and special effects. But on another level, the contrast between bows and arrows on one side, and death-dealing hovercraft on the other, accentuates the saga's David vs. Goliath angle or, in this case, Katniss vs. the Capitol.

Here are a few of the technological trends that provide the twists in "The Hunger Games," along with real-world analogs:

What? No cellphones? Much has been made of the fact that the starving, downtrodden residents of Panem's districts don't seem to have access to cellphones or the Internet. Instead, they have to huddle around giant television sets to find out what their overlords in the Capitol want them to see. But if you think of Panem as a fictional tweak of modern-day North Korea, "The Hunger Games" might not be that far off the mark: You've got a leadership capable of long-range missile launches, exercising virtually total control over what its impoverished populace sees and hears. Cellphones were outlawed until 2008, and even today they're confiscated from international visitors upon arrival. Internet access and international calling are limited to the elite.

The outlook for change is mixed: Today, a million North Koreans are said to be using mobile phones, but the State Department's Alec Ross told the Korea Times during a recent visit to Seoul that "it will be very difficult for technology to drive change in North Korea, given the extreme measures that North Korea has taken to create a media blackout." That's life in Panem ... er, Pyongyang.

Genetic engineering The most vivid special effects are connected to genetic engineering of various organisms, including humanized animals. To minimize the plot-spoiler effect, the only "muttation" I'll mention in detail is the mockingjay, which figures so prominently in the advance publicity and provides the title for the third book in Suzanne Collins' "Hunger Games" trilogy. The geniuses at the Panem high command created genetically modified birds known as jabberjays that were able to listen in on rebel conversations and report them back to the authorities. When the rebels caught onto this, they started feeding the jays false information. And when the Capitol figured this out, they left the jabberjays to fend for themselves. Male jabberjays mated with female mockingbirds, resulting in birds that could learn and repeat musical notes but not human speech.

The twist illustrates a time-honored movie maxim about genetic engineering, enunciated in the first "Jurassic Park" film: "Life will not be contained." That may be putting it too simply, but the field has certainly raised a lot of questions about how to keep genetic genies in the bottle. This month, more than 100 groups issued a call to hold back on synthetic biology until new guidelines are drawn up.

Environmental groups call for tighter regulation of ‘extreme genetic engineering’

Genetically engineered microbes that might one day churn out biofuels, clean up toxic waste or generate new medicines need to be proved safe before they are released into the environment, a coalition of 111 environmental and social justice groups said Tuesday.

Led by the environmental advocacy group Friends of the Earth, the coalition also called for stronger government regulations over extreme genetic engineering and a moratorium on the commercial use and release of lab-created organisms.

Without proper safeguards, we risk letting synthetic organisms and their products out of the laboratory with unknown potential to disrupt ecosystems, threaten human health and undermine social, economic and cultural rights, the coalition said in a new report.

The technology to manipulate the genes of bacteria, yeast and other organisms has existed since the 1970s, leading to pest-resistant crops, bacteria that produce human insulin and other breakthroughs.

But in 2010, biologist J. Craig Venter announced that his institute had invented synthetic biology by transplanting the entire genome of one bacterium into a different species, which then reproduced. While not qualifying as an entirely new organism, the lab-built microbe did fuel concerns that this technology presented new and hard-to-quantify risks.

The White House jumped in, with the Presidential Commission for the Study of Bioethical Issues recommending in 2010 that federal agencies adopt a middle course that encouraged enhanced oversight and careful consideration of possible risks but no new laws or regulations.

Environmental groups say those measures dont go far enough.

The field is evolving incredibly rapidly in the face of almost no regulation, said Eric Hoffman of Friends of the Earth. A moratorium puts the brakes on to allow society time to decide which applications are okay and which arent.

Representatives of the biotechnology industry say that genetically modified organisms are already adequately regulated by the Environmental Protection Agency, the U.S. Agriculture Department, the Food and Drug Administration and other agencies.

I think the reports kind of silly, frankly. It makes no sense to call for a moratorium, said Brett Erickson, executive vice president of the Biotechnology Industry Organization, a trade group. Weve been doing genetic engineering for 30years, and weve been doing it safely. People are hyping this as something new.

Fast-track breeding could bring a second Green Revolution

Green revolution:Fast-track breeding is beginning to develop crops that can produce more and healthier food without controversial genetic engineering.

In Zambia during the current planting season, a corn crop will go into the fields that begins the process of rapidly boosting vitamin A content by as much ten-fold helping to address a nutritional deficiency that causes 250,000-500,000 children to go blind annually, most of them in Africa and Asia. In China, Kenya, and Madagascar, also this planting season, farmers will put out a crop of Artemisia annua that yields 20 to 30 percent more of the chemical compound artemisinin, the basis for what is now the worlds standard treatment for malaria.

Both improvements are happening because of fast-track breeding technology that promises to produce a 21st-century green revolution. It is already putting more food on tables though its unclear whether it can add enough food to keep pace as the worlds human population booms to 9 billion people by 2050.

Fast-track breeding is also giving agronomists a remarkable tool for quickly adapting crops to climate change and the increasing challenges of drought, flooding, emerging diseases, and shifting agricultural zones. And it can help save lives: In the absence of prevention, half those victims of vitamin A deficiency now die shortly after going blind, according to the World Health Organization; and in 2010, lack of adequate treatment meaning artemisinin contributed to the deaths of 655,000 children from malaria.

The fast-track technology, called marker-assisted selection (MAS), or molecular breeding, takes advantage of rapid improvements in genetic sequencing, but avoids all the regulatory and political baggage of genetic engineering. Bill Freese, a science policy analyst with the Center for Food Safety, a nonprofit advocacy group, calls it a perfectly acceptable tool. I dont see any food safety issue. It can be a very useful technique if its used by breeders who are working in the public interest.

Molecular breeding isnt genetic engineering, a technology that has long alarmed critics on two counts. Its methods seem outlandish taking genes from spiders and putting them in goats, or borrowing insect resistance from soil bacteria and transferring it into corn and it has also seemed to benefit a handful of agribusiness giants armed with patents, at the expense of public interest.

By contrast, molecular breeding is merely a much faster and more efficient way of doing what nature and farmers have always done, by natural selection and artificial selection respectively: It takes existing genes that happen to be advantageous in a given situation and increases their frequency in a population.

In the past, farmers and breeders did it by walking around their fields and looking at individual plants or animals that seemed to have desirable traits, like greater productivity, or resistance to a particular disease. Then they went to work cross-breeding to see if they could tease out that trait and get it to appear reliably in subsequent generations. It could take decades, and success at breeding in one trait often meant bringing along some deleterious fellow traveler, or inadvertently breeding out some other essential trait.

Audubon center in Algiers logs another breakthrough in genetic engineering of endangered cats

A year after introducing the first pair of rare African black-footed kittens conceived through in vitro fertilization, the scientists at the Audubon Center for Research of Endangered Species in Algiers have announced the arrival of another kitten that, genetically, is their sister, and the first kitten of her type to be carried in the womb of a domestic cat. The same parents contributed to the frozen embryos that produced the two males born last year and this year's female.

A black-footed cat served as the surrogate mother for last year's litter. Researchers next sought to show that vastly more plentiful domestic cats can serve as surrogate mothers in efforts to save the small wild cat from extinction.

"Being able to use domestic cats adds another extra dimension to that, being able to produce more," said Earle Pope, acting director of the center. Only 53 of the cats, which are native to South Africa, live in zoo collections in the United States.

Domestic and African black-footed are different species of cat but members of the same group of felines. Their similar sizes and gestation lengths, Pope said, appear to be what made the pregnancy and birth physically possible even though the genetic makeup of the kitten differed from the mother.

"They're considered to be of the same lineage," he said. "Somewhere back a couple of million years ago, they're descended from the same ancestor."

The kitten, named Crystal, was born on Feb. 6 to domestic cat Amelie without any human assistance in the birth itself. It exhibits all the characteristics of a black-footed cat despite being nurtured by a domestic cat mother, Pope said.

"It's not changed genetically in any way," from other black-footed cats, he said. "It is totally a black-footed cat in behavior."

Researchers handle the kitten almost every day as they study it, but she remains decidedly unadapted to human contact.

"It just wants you to leave it alone and stay away from it," Pope said. "It gets along beautifully with the domestic cat mother. They don't know, or do not care, that it's a different species."

Scientists started gathering the genetic material that eventually created the kitten in 2003, when they collected and froze a sperm sample from a black-footed cat named Ramses that lived at a research center in Nebraska. In 2005, they thawed the sperm and combined them with eggs from Zora, a cat living at Audubon. That produced 11 embryos, which went into deep freeze.

How Human Engineering Could Be the Solution to Climate Change

Some of the proposed modifications are simple and noninvasive. For instance, many people wish to give up meat for ecological reasons, but lack the willpower to do so on their own. The paper suggests that such individuals could take a pill that would trigger mild nausea upon the ingestion of meat, which would then lead to a lasting aversion to meat-eating. Other techniques are bound to be more controversial. For instance, the paper suggests that parents could make use of genetic engineering or hormone therapy in order to birth smaller, less resource-intensive children.

The lead author of the paper, S. Matthew Liao, is a professor of philosophy and bioethics at New York University. Liao is keen to point out that the paper is not meant to advocate for any particular human modifications, or even human engineering generally; rather, it is only meant to introduce human engineering as one possible, partial solution to climate change. He also emphasized the voluntary nature of the proposed modifications. Neither Liao or his co-authors, Anders Sandberg and Rebecca Roache of Oxford, approve of any coercive human engineering; they favor modifications borne of individual choices, not technocratic mandates. What follows is my conversation with Liao about why he thinks human engineering could be the most ethical and effective solution to global climate change.

Judging from your paper, you seem skeptical about current efforts to mitigate climate change, including market based solutions like carbon pricing or even more radical solutions like geoengineering. Why is that?

Liao: It's not that I don't think that some of those solutions could succeed under the right conditions; it's more that I think that they might turn out to be inadequate, or in some cases too risky. Take market solutions---so far it seems like it's pretty difficult to orchestrate workable international agreements to affect international emissions trading. The Kyoto Protocol, for instance, has not produced demonstrable reductions in global emissions, and in any event demand for petrol and for electricity seems to be pretty inelastic. And so it's questionable whether carbon taxation alone can deliver the kind of reduction that we need to really take on climate change.

With respect to geoengineering, the worry is that it's just too risky---many of the technologies involved have never been attempted on such a large scale, and so you have to worry that by implementing these techniques we could endanger ourselves or future generations. For example it's been suggested that we could alter the reflectivity of the atmosphere using sulfate aerosol so as to turn away a portion of the sun's heat, but it could be that doing so would destroy the ozone layer, which would obviously be problematic. Others have argued that we ought to fertilize the ocean with iron, because doing so might encourage a massive bloom of carbon-sucking plankton. But doing so could potentially render the ocean inhospitable to fish, which would obviously also be quite problematic.

One human engineering strategy you mention is a kind of pharmacologically induced meat intolerance. You suggest that humans could be given meat alongside a medication that triggers extreme nausea, which would then cause a long-lasting aversion to meat eating. Why is it that you expect this could have such a dramatic impact on climate change?

Liao: There is a widely cited U.N. Food and Agricultural Organization report that estimates that 18% of the world's greenhouse gas emissions and CO2 equivalents come from livestock farming, which is actually a much higher share than from transportation. More recently it's been suggested that livestock farming accounts for as much as 51% of the world's greenhouse gas emissions. And then there are estimates that as much as 9% of human emissions occur as a result of deforestation for the expansion of pastures for livestock. And that doesn't even to take into account the emissions that arise from manure, or from the livestock directly. Since a large portion of these cows and other grazing animals are raised for consumption, it seems obvious that reducing the consumption of these meats could have considerable environmental benefits.

Even a minor 21% to 24% reduction in the consumption of these kinds of meats could result in the same reduction in emissions as the total localization of food production, which would mean reducing "food miles" to zero. And, I think it's important to note that it wouldn't necessarily need to be a pill. We have also toyed around with the idea of a patch that might stimulate the immune system to reject common bovine proteins, which could lead to a similar kind of lasting aversion to meat products.

Your paper also discusses the use of human engineering to make humans smaller. Why would this be a powerful technique in the fight against climate change?

Liao: Well one of the things that we noticed is that human ecological footprints are partly correlated with size. Each kilogram of body mass requires a certain amount of food and nutrients and so, other things being equal, the larger person is the more food and energy they are going to soak up over the course of a lifetime. There are also other, less obvious ways in which larger people consume more energy than smaller people---for example a car uses more fuel per mile to carry a heavier person, more fabric is needed to clothe larger people, and heavier people wear out shoes, carpets and furniture at a quicker rate than lighter people, and so on.

Students at Diamond Bar’s Brahma Tech debate genomic engineering ethics

DIAMOND BAR - Is it appropriate to use emerging synthetic genomic engineering technology to build new forms of "life"? Should genetic engineering techniques and processes be used in agriculture?

These were some of the issues debated by Brahma Tech students at Diamond Bar High last week. The great debate was part of a week of competition for the Technology Student Association.

The Brahmas recently became the first high school in California to join the national organization, according to technology teacher Alina Gallardo.

More than 150,000 middle and high school students throughout America belong to the association. Members learn about technology through competitions, events and conferences.

Sophomore Alice Jin spearheaded the effort to join the Technology Student Association.

"I found out about it on the Internet, then talked to my classmates about forming a local chapter," the 16-year-old explained.

Diamond Bar has more than 400 students in the Brahma Tech Academy. The academy is a specialized math, science and technology program with four career paths.

"Students also have to do 150-hour internships with high-tech companies," Gallardo explained.

It attracts students like 17-year-old Drew Liu. "I want to major in bioengineering in college," the senior said.

Liu was one of the group of students competing in technology week. Earlier, the techies made videos. Participants had to write, shoot and edit

Texas A&M Researchers Create Goat With Malaria Vaccine In Her Milk

Over at the Texas A&M Reproductive Sciences Complex, you'll find several animals with unique capabilities.

Goat number 21 is one of those creatures.

"This project is one of the most interesting that we've been involved with because it has so much potential world wide," said Texas A&M researcher Charles Long.

Long & fellow A&M researcher Mark Westhusin keep a careful eye on goat number 21 because her milk holds a vaccine for malaria.

"There are lots of different things that one can think about producing in the milk. Malaria vaccine is one that's really important because there's a big demand for it in a lot of impoverished countries," said Westhusin.

Through genetic engineering, this goat could be the golden goose when it comes to preventing malaria in third world countries. A disease that kills a child in Africa every minute according to the World Health Organization.

"What you'd have is an animal that could be in any village around the world and all natives would have to do is drink some of that milk and be immunized against malaria," said Long.

But before any of that happens, this goat has to jump through a lot of hoops.

"We'd love to start air dropping goats into Africa but the reality is we're not going to be able to achieve that objective for another five or 10 years at least," joked Long.

"What we have to do is milk the goat, purify the protein, then we'd have to do all kinds of clinical testing and safety testing. Just like as if we were to take any drug and go to market with it," said Westhusin.

From ‘Refrigerator Mothers’ to untangling the genetic roots of autism

Public release date: 7-Mar-2012 [ | E-mail | Share ]

Contact: Michael Bernstein m_bernstein@acs.org 202-872-6042 American Chemical Society

With the "Refrigerator Mother" notion about the cause of autism a distant and discredited memory, scientists are making remarkable progress in untangling the genetic roots of the condition, which affects millions of children and adults, according to an article in the current edition of Chemical & Engineering News. C&EN is the weekly newsmagazine of the American Chemical Society, the world's largest scientific society.

In the story, C&EN Associate Editor Lauren K. Wolf points out that most people in the 1960s believed autism resulted from a lack of maternal warmth and emotional attachment. It was a hypothesis popularized by Austrian-born American child psychologist and writer Bruno Bettelheim. Now scientists around the globe are focusing on genes that have been implicated in autism and related conditions, collectively termed "autism spectrum disorders." That research may solve mysteries about autism, which affects 1 in 110 children in the U.S. Among them: what causes autism, why does it affect more boys than girls and what can be done to prevent and treat it?

C&EN explains that scientists now have solidly implicated certain genes as being involved in autism. Most of those genes play a role in the transmission of signals through the junctions or "synapses" between nerve cells. Synapses are the territory where one nerve releases a chemical signal that hands off messages to an adjoining nerve. The human brain has an estimated 1,000 trillion synapses, and they are hot spots for miscommunications that underpin neurological disorders like autism. Scientists now are gleaning information on what those genes do, what brain circuits they affect and how the proteins they produce function. In doing so, they are paving the way for future medications for autism spectrum disorders.

New Rochelle, NY, Mar 07, 2012--More than 2 million teenagers suffer from depression in the U.S. Recent drug warnings and study results have led to increased controversy surrounding the treatment of adolescent depression. A state-of-the-art issue reporting on the latest research findings on antidepressant medications combined with appropriate therapeutic strategies has been published by Journal of Child and Adolescent Psychopharmacology, a peer-reviewed journal from Mary Ann Liebert, Inc. The special issue on psychopharmacology of adolescent depression is available free on the Journal of Child and Adolescent Psychopharmacology website.

"There are no radically new treatments on the horizon for the treatment of depression, and so we have to do better with the treatments we have available," says Graham J. Emslie, MD, Guest Editor of the issue and Director of Child Psychiatry at University of Texas Southwestern Medical Center, Dallas. "Few youths with depression receive adequate treatment."

The issue focuses on the controversy, the data, and the challenges and opportunities in the care of adolescents with major depressive illness. The articles cover a wide range of issues that all contribute to the goal of improving outcomes. Included in the issue, Greg Clarke, PhD et al., Kaiser Permanente Center for Health Research (Portland, OR), present an evaluation of new and refill antidepressant prescribing practices among physicians before and after warnings related to teen suicide risk were issued. Kenneth Wells, MD, MPH and colleagues from University of California, Los Angeles, and Stony Brook University (NY), explore the effectiveness of appropriate care delivered in a primary care setting. Dr. Emslie and colleagues from UT Southwestern Medical Center examine the common problem of insomnia in youths with depression and its impact on treatment.

"Depression is a major public health concern among young people, particularly teens, but many people have a hard time talking about it," says Harold S. Koplewicz, MD, Editor-in-Chief of Journal of Child and Adolescent Psychopharmacology, and President, Child Mind Institute, New York, NY. "Advancing research is one way we can work to change a culture of denial that too often stands in the way of effective and sometimes life-saving treatment."

VCU study: Bad environment augments genetic risk for drug abuse

Public release date: 5-Mar-2012 [ | E-mail | Share ]

Contact: Sathya Achia Abraham sbachia@vcu.edu 804-827-0890 Virginia Commonwealth University

RICHMOND, Va. (March 5, 2012) The risk of abusing drugs is greater even for adopted children if the family environment in which they are raised is dysfunctional, according to a new study conducted by a collaborative team from Virginia Commonwealth University and Lund University in Sweden.

Previous research suggests that drug abuse is strongly influenced by a mix of genetic factors and the environment, including influences of family and peers. That research is primarily based on twin studies and typically involves families that are intact. Relatives that share genes and environment make it difficult to determine if the family dysfunction is linked to the drug abuse or if it is genetics at play. There have been no large-scale adoption studies performed to verify the findings, until now.

In the study, published online March 5 in the journal Archives of General Psychiatry, researchers examined how genetic and environmental factors contribute to the risk for drug abuse in adoptees. Using a large and representative adoption sample from Sweden, they demonstrate that genetic factors played a moderate role in the liability to drug abuse.

"For an adoptee, having a biological parent with drug abuse who did not raise you doubles your risk for drug abuse," said first author Kenneth Kendler, M.D., director of the VCU Virginia Institute for Psychiatric and Behavioral Genetics.

"But we also found an important role for environmental factors. If you have an adoptive sibling - with whom you have no genetic relationship - develop drug abuse, that also doubles your risk for drug abuse,"

More importantly, according to Kendler, the team showed that the impact of your genes on risk for drug abuse is much stronger if you are raised in a high-risk rather than a low-risk environment.

"A bad environment can augment the effect of genetic risk on drug abuse," he said.

Kendler, professor of psychiatry, and human and molecular genetics in the VCU School of Medicine, and a team of researchers from Lund University led by Jan Sundquist, M.D., Ph.D., professor and director of the Center for Primary Health Care Research, and Kristina Sundquist, M.D., Ph.D., professor of family medicine at the Center for Primary Health Care Research, analyzed nine public registry data sets compiled between 1961 and 2009 of adoptees and their biological and adoptive relatives from Sweden.

31 Teams Grapple In STEM Competition

Posted: Monday, March 5, 2012 10:13 am | Updated: 10:46 am, Mon Mar 5, 2012.

Dozens of high school and middle school girls spent Saturday, Feb. 18 engineering brick walls, mixing chemical solutions, solving genetic and forensic quandaries, and conquering tricky logic problems at Foxcroft Schools K2M Expedition: The STEM Summit. Foxcroft School in Middleburg and Norwood School in Bethesda, MD, captured the competitions high school and middle school titles, respectively.

It was an outstanding day for all involved, Foxcroft Head of School Mary Louise Leipheimer stated. What these girls can do with math, science and technology is amazing. I dont know when Ive been so proud of our school.

The STEM Summit attracted a number of talented students from Virginia, Maryland and Washington, DC, with girls from 19 high schools and 12 middle schools competing. Working in teams of 3 or 4, students solved problems that draw on STEM (Science, Technology, Engineering, and Mathematics) skills. Challenges included engineering a brick wall with the longest possible overhang, mixing chemical solutions to identify each element, solving a genetics problem called Whos Your Daddy? and conquering tricky logic problems. The middle school competition also included a forensics exercise that involved analyzing fingerprints and fiber samples.

The event was sponsored by K2M, Inc., a Leesburg firm that develops technological innovations for surgeons to treat complex spinal disorders. Two of the companys young engineers conducted one of the STEM Summit events, and CEO Eric Major came to watch.

We were so impressed with the energy, enthusiasm and intellectual curiosity of the Foxcroft girls who visited our lab last spring, stated Major, referring to a field trip by the Schools Engineering and AP Biology classes to learn about K2Ms engineering. So we thought partnering with Foxcroft to sponsor this event made a lot of sense.

Included in the collection are Sea Monkeys and GloFish. From the article: 'One of the cool things about natural history museums is that they show you how nature has changed over time, adapting to volatile conditions and extreme challenges. And nothing is more volatile, extreme, or challenging than the human race, so it makes sense that there would be a museum to chronicle just how much weve messed with plants, animals, the climate, and in general the world around us. The Center for PostNatural History, opening this week in Pittsburgh, is that museum.'" Related Links Post

Brandeis Leads Study of Attitudes on Genetic Tests for Epilepsy

By a GenomeWeb staff reporter

NEW YORK (GenomeWeb News) Researchers from Brandeis University and Columbia University plan to use a $200,000 grant to survey and investigate public attitudes about taking genetic tests for epilepsy risk, Brandeis said this week.

Funded through a $200,000 sub-contract under a grant from the National Institute of Neurological Disorders and Stroke, the project will involve in-depth interviews and analysis and clinical genetic testing.

In the first part of the effort, the researchers will survey 1,053 individuals from 115 families to evaluate whether they would like to take genetic tests, and what they see as the benefits and downsides of testing for risk, as well as their views on how the stigmatization of epilepsy could affect the quality of their lives.

The researchers also will offer clinical genetic tests to individuals from 21 families containing 195 individuals with an uncommon form of epilepsy called autosomal dominant partial epilepsy with auditory features, or ADPEAF.

Half of these families were previously found to have specific gene mutations, but they have never been offered their individual results or the chance to engage in linked discussions about their views.

"The intention of the in-depth interviews is to explore, in much greater depth than can be done in a survey, what genetic information actually means in peoples' lives and how they plan to make use of it," Sara Shostak, assistant professor in the department of sociology at Brandeis, said in a statement.

In previous research, Shostak found that people are concerned about genetics-related issues when they think about future generations and having families. In addition, she found that people with epilepsy and their families hope that genetic information about the disease could help to lessen the stigma and discrimination by influencing public understanding about the disease.

Currently, around 25 genes have been associated with specific epilepsy syndromes.

New treatment using inhaled interferon may improve lung function in pulmonary fibrosis

Public release date: 29-Feb-2012 [ | E-mail | Share ]

Contact: Cathia Falvey cfalvey@liebertpub.com 914-740-2100 Mary Ann Liebert, Inc./Genetic Engineering News

New Rochelle -- Inhaled interferon-gamma may be an effective treatment for idiopathic pulmonary fibrosis (IPF), a chronic and progressive form of lung disease caused by excessive formation of fibrotic, or scar tissue, in the lungs, according to an article published in Journal of Aerosol Medicine and Pulmonary Drug Delivery (http://www.liebertpub.com/jamp), a peer-reviewed journal from Mary Ann Liebert, Inc. (http://www.liebertpub.com) The article on inhaled interferon-gamma (http://online.liebertpub.com/doi/abs/10.1089/jamp.2011.0919) is available free online at the Journal of Aerosol Medicine and Pulmonary Drug Delivery website.

Normally, systemic delivery of interferon-gamma can cause substantial side effects; however, delivery of aerosolized interferon-gamma directly into the lungs was shown to be safe and was associated with significantly reduced levels of profibrotic regulatory proteins. Keith Diaz, MD, Shibu Skaria, MD, Keith Harris, MD, Mario Solomita, DO, Stephanie Lau, MD, Kristy Bauer, MD, Gerald Smaldone, MD, PhD, and Rany Condos, MD, State University of New York, Stony Brook and New York University School of Medicine, NYC, show that inhalation of interferon-gamma in aerosol form three times a week for at least 80 weeks was well-tolerated by patients, with no systemic side effects.

The authors verified the presence of the drug in the material collected on lung washes and documented no change in the level of interferon-gamma in the blood during the treatment period. The report shows the results of pulmonary function tests, including forced vital capacity (FVC) and total lung capacity (TLC), and the effects of treatment on a six-minute walk test in the article entitled "Delivery and Safety of Inhaled Interferon-gamma in Idiopathic Pulmonary Fibrosis." (http://online.liebertpub.com/doi/abs/10.1089/jamp.2011.0919)

"There is no treatment for Idiopathic Pulmonary Fibrosis, a disease usually fatal within 3-5 years," says Gerald C. Smaldone, MD, PhD, Editor-in-Chief of the Journal and a coauthor of this article, and Professor and Chief, Division of Pulmonary and Critical Care Medicine at SUNY-Stony Brook. "The scientific community expected the injected form of interferon-gamma to help, but those studies failed. We have shown that inhaled interferon is safe with very high levels in the lungs. Now is the time to repeat the clinical trials with the inhaled form of this therapy."
