The Gigaom interview: Why synthetic biology and the Netflix model are the future of medicine

23 hours ago May. 3, 2014 - 8:00 AM PDT

Look inside nearly any medicine cabinet in the U.S. and there will be a few bottles of prescription pills. They might be blue, white, round or square, but their development has followed the same pattern for decades: One of the few gigantic pharmaceutical companies that have come to dominate the industry pours millions, or even billions, of dollars into designing and getting a drug approved. Then the same pill is prescribed to every single person.

Molecular biologist and futurist Andrew Hessel doesnt see that model lasting for much longer. He envisions a world in which every individual receives pharmaceutical drugs perfectly formulated to their genetic and medical needs for a fraction of what treatment would currently cost.

That future is on its way. Companies like Cambrian Genomics are making it possible for anyone to print strands of DNA. Autodesks bio/nano/programmable matter group, where Hessel is a distinguished researcher, is building design software known as Project Cyborg that will allow individuals to make 3D models of living matter.With the price of genetic sequencing dropping every year, he believes it wont be long before anyone who wants to will be able to create with the building blocks that make up life itself. The future of healthbelongs to any startup that wants in on it, instead of just the Genentechs of the world.

By learning to read and better understand the molecular world and self-assembling world, we have the opportunity to create really novel things using the same machinery that creates a plant or a cat, which is kind of fun, Hessel said. The genetic language is like the internet protocol: open, and so its a really fascinating language to learn. You learn one language and you can basically speak all of life, which is really cool. Its my favorite programming language.

What follows is an edited transcription of our conversation.

Signe Brewster:Why do you think individuals should have that kind of power?

Andrew Hessel: Every time I hear of a big challenge for the world, whether its, oh, how do you cure cancer or reduce our dependence on fossil fuels or clean up water or create anything sustainable, for me, its these technologies that are going to apply. If we can democratize their use and keep them open and transparent and make better tools for people to do the work, then were going to change the world in ways that are positive.

What would the pharmaceuticalindustry look like if the big companies were not in charge?

HFSP Grant for International Research Team MDC Participates

30.04.2014 - (idw) Max-Delbrck-Centrum fr Molekulare Medizin (MDC) Berlin-Buch

Four researchers from the U.S., Italy and Germany, among them Professor Nikolaus Rajewsky from the Max Delbrck Center for Molecular Medicine (MDC) Berlin-Buch, have been awarded a grant of more than 1.2 million dollars from the Human Frontier Science Program Organization (HFSPO), Strasbourg, France, for a project in cancer research.* In collaboration with Professor Brian Brown from the Mount Sinai School of Medicine, New York, USA, the researchers aim to decipher non-coding RNA regulatory networks and their role in the onset of cancer. In 2014, HFSPO is awarding about 35 million dollars to the 34 winning teams that have been selected in a rigorous selection procedure out of 844 proposals. A non-coding RNA (nc-RNA) is an RNA molecule which is not translated into protein. The geneticist Professor Brown and systems biologist Professor Rajewsky, together with their collaboration partners in Rome and Boston, aim to shed light on the complex interactions and possible competition situations of non-coding RNAs. These provide fundamental insights into the function of gene-regulatory networks and their role in the pathogenesis of cancer and other diseases. To achieve this, an interdisciplinary approach is necessary for which the team combines complementary expertise and applies molecular biological, genetic and biochemical methods along with computer-based methods.

Novel therapeutic agent for Tamiflu-resistant pH1N1 influenza virus discovered

PUBLIC RELEASE DATE:

24-Apr-2014

Contact: Denis Kainov denis.kainov@fimm.fi 358-504-152-35460 University of Helsinki

In 2009 the influenza pH1N1 virus caused the first flu pandemic in the 21st century. The virus reached Finland in May 2009 and killed more than 50 people in the country. Since 2011 the pH1N1 virus infects Finns mainly during flu epidemics (winter/spring seasons).

Infections with influenza pH1N1 virus vary from asymptomatic to serious complicated illnesses. World Health Organization has recommended Tamiflu for treatment of patients with severe or progressive illness. The disadvantage of this drug is that it targets viral proteins which mutate quickly and the virus develops resistance to it.

The Medical Systems Virology group at FIMM, together with collaborators has recently sequenced genomes of 135 pH1N1 influenza strains isolated from Finnish patients in 2009-2013 and found one Tamiflu-resistant strain from the 2012-2013 epidemic season. The study was published in the Genome Announcements journal and is now available online.

This finding suggests that there could be more resistant strains in upcoming seasons. Therefore, there is a need for the development of new antiviral agents against pH1N1, says Dr. Triin Lakspere.

In another study published this week the group investigated influenza pH1N1 virus-host cell interaction in detail and found that certain host function could be temporally inhibited with small molecule MK2206 to block influenza infection in cell culture.

Importantly, the virus was unable to acquire resistance to host-directed MK2206 in contrast to virus-directed Tamiflu. This small molecule is in clinical trials against cancer and has high specificity and good pharmacological properties, which could warrant its further development as antiviral drug for treatment of pH1N1 virus infection, Dr. Oxana Denisova says.

Ginseng Can Treat and Prevent Influenza and RSV

Contact Information

Available for logged-in reporters only

Newswise ATLANTA--Ginseng can help treat and prevent influenza and respiratory syncytial virus (RSV), a respiratory virus that infects the lungs and breathing passages, according to research findings by a scientist in Georgia State Universitys new Institute for Biomedical Sciences.

In a recent issue of Nutrients and an upcoming publication of the International Journal of Molecular Medicine, Sang-Moo Kang reports the beneficial effects of ginseng, a well-known herbal medicine, on human health.

Kangs primary research focuses on designing and developing effective vaccines against viral diseases such as influenza virus and RSV, but he partnered with a university and research institutes in South Korea that wanted international collaborative projects to study if ginseng can be used to improve health and protect against disease because of the potential benefit in fighting these viruses. Ginseng has been reported to have anticancer, anti-inflammatory and immune modifying abilities.

Seasonal influenza is a serious respiratory disease that causes annual epidemics in humans worldwide, resulting in about three to five million cases of severe illness and about 250,000 to 500,000 deaths, according to the World Health Organization. Influenza can spread quickly, and new, unexpected pandemic influenza viruses may emerge at any time and cross over to different species. The H1N1 influenza virus, a new strain known as swine flu that emerged in 2009, spread rapidly to more than 74 countries. There are also challenges with existing influenza vaccines, such as required annual updates and no protection against pandemic strains and bird flu.

In addition, there are no vaccines available for RSV, which affects millions and is the leading cause of inflammatory bronchiolitis pneumonia and viral death in infants and in some elderly adults.

In his study published in Nutrients, Kang investigated whether red ginseng extract has preventive effects on influenza A virus infection. He found that red ginseng extract improves the survival of human lung epithelial cells infected with influenza virus. Also, treatment with red ginseng extract reduced the expression of genes that cause inflammation.

After infection with influenza A virus, mice that were orally administered ginseng over a long time showed multiple immune modifying effects, such as stimulated antiviral production of proteins important in immune response and fewer inflammatory cells in their bronchial walls. The study indicates the beneficial effects of red ginseng extract on preventing influenza A virus infections could result from immune modifying capabilities of ginseng.

In his upcoming publication in the International Journal of Molecular Medicine, Kang investigated whether Korean red ginseng extract has antiviral effects, or the ability to treat RSV infection. Kang found Korean red ginseng extract improved the survival of human lung epithelial cells against RSV infection and inhibited the virus from replicating, or multiplying, in the body. In addition, treatment with Korean red ginseng extract suppressed the expression of RSV-induced inflammatory genes and the formation of chemically reactive molecules containing oxygen, which play a role in virus-induced epithelial damage in RSV.

Ginseng Can Treat and Prevent Influenza and RSV

Malfunction in molecular 'proofreader' prevents repair of UV-induced DNA damage

PUBLIC RELEASE DATE:

21-Apr-2014

Contact: Anita Srikameswaran srikamav@upmc.edu 412-578-9193 University of Pittsburgh Schools of the Health Sciences

PITTSBURGH, April 21, 2014 Malfunctions in the molecular "proofreading" machinery, which repairs structural errors in DNA caused by ultraviolet (UV) light damage, help explain why people who have the disease xeroderma pigmentosum (XP) are at an extremely high risk for developing skin cancer, according to researchers at the University of Pittsburgh School of Medicine and the University of Pittsburgh Cancer Institute (UPCI). Their findings will be published this week in the early online version of the Proceedings of the National Academy of Sciences.

Previous research has shown that a DNA-repair protein called human UV-damaged DNA-binding protein, or UV-DDB, signals for a repair when two UV-DDB molecules bind to the site of the problem, said senior investigator Bennett Van Houten, Ph.D., the Richard M. Cyert Professor of Molecular Oncology, Pitt School of Medicine, and co-leader of UPCI's Molecular and Cell Biology Program.

"Our new study shows UV-DDB makes stops along the DNA strand and transiently attaches to it, causing a proofreading change in the protein's conformation, or shape. If the DNA is damaged the protein stays, if the DNA is not damaged the protein leaves," Dr. Van Houten said. "When it comes to a spot that has been damaged by UV radiation, two molecules of UV-DDB converge and stay tightly bound to the site, essentially flagging it for the attention of repair machinery."

The researchers followed the trail of single molecules of UV-DDB by tagging them with light-emitting quantum dots, enabling them to watch the molecules jump from place to place in real time on both normal and UV-exposed DNA strands.

They also tracked a mutant UV-DDB protein associated with XP, an inherited, incurable disease of light sensitivity that affects about 1 in 250,000 people. They found that the mutant UV-DDB molecules are still capable of binding to DNA, but continued to slide along the DNA rather than staying put to signal where the fix was needed.

"Without this important damage control, UV-induced errors could accumulate to cause cell alterations that foster cancer development," Dr. Van Houten said. "Like a bus with no brakes, the XP-associated UV-DDB complex stays on the road and sees possible passengers, but keeps going past the stop."

Pressure Relief Valve in Cellular Membrane Identified

16.04.2014 - (idw) Max-Delbrck-Centrum fr Molekulare Medizin (MDC) Berlin-Buch

Regulation of cell volume is critical for the bodys cells, f. e. during cellular exposure to fluids of varying salt concentrations, in cell division, cell growth, but also in diseases such as cancer, stroke and myocardial infarction. A certain chloride channel, a membrane protein that allows the passage of the chloride ion, is of crucial importance in volume regulation. It is activated by the swelling of the cell and then releases chloride ions and organic matter (osmolytes) from the cell. Researchers in Berlin-Buch have now succeeded for the first time in elucidating the molecular identity of this volume-regulated anion channel (VRAC) (Science Express, DOI: 10.1126/science.1252826)*. Researchers led by Professor Thomas J. Jentsch (Max Delbrck Center for Molecular Medicine, MDC, Berlin-Buch/Leibniz-Institut fr Molekulare Pharmakologie, FMP) identified a molecule, LRRC8A, which is an essential constituent of the volume-regulated anion channel (VRAC). This protein needs to be assembled with related proteins (LRRC8B to E) to form channels with probably six subunits. They could also show for the first time that these chloride channels are also permeable to small organic molecules such as taurine or amino acids. For over 20 years, research groups across the globe have been seeking to elucidate the molecular structure of the volume-regulated anion channel (VRAC). It took Jentschs team almost four years to achieve this breakthrough.

The regulation of cell volume is important for many functions in the organism. The volume-regulated anion channel (VRAC) which Thomas Jentsch and his coworkers Felizia Voss and Tobias Stauber now identified at the molecular level is expressed in all vertebrate cells. If a particular cell volume is exceeded, the channel opens and permits the outflow of osmolytes such as chloride ions as well as small organic molecules such as taurine and amino acids. By contrast, cations such as potassium or sodium cannot permeate.

Once the channel is opened, chloride and other osmolytes pass in a passive process called diffusion. Due to its biophysical properties the channel only allows anions and certain organic compounds to pass. Thus, the cell reduces the concentration of its osmolytically active constituents to (or even below) that of the surrounding fluid. At the same time, the water content of the cell decreases as the water molecules flow out via aquaporins in the cell membrane. The volume of the cell decreases again.

LRRC8A was discovered as a VRAC component using a genome-wide RNA interference (siRNA) screen in collaboration with Katina Lazarow and Jens von Kries from the FMP Screening Unit. By means of short RNA snippets, the translation of the genetic information into the corresponding proteins can be suppressed. Using a one-by-one approach in a large-scale cell culture experiment, the Berlin group transiently silenced the products of all approximately 20,000 human genes. In an automated screening process the researchers investigated which of the genes are required for the swelling-activated anion flux across the cell membrane. The approximately 130,000 time-dependent ion flux measurements were statistically analyzed with help from the Bioinformatics Group of the MDC (Nancy Mah/Miguel Andrade-Navarro).

The essential role of LRRC8 proteins in the volume-regulated anion channel was verified using CRISPR/Cas technology, which just became available during the past two years. With this method, specific genes on the chromosomes can be disrupted completely. Different combinations of LRRC8 proteins, all including the obligate LRRC8A, either by omitting some of the family members from gene disruption or by reconstituting different combinations led to different electrophysiological properties of the channel. This allows us to explain the behavior of the channel in different tissues which until now had remained elusive, Thomas Jentsch said.

Deciphering the molecular structure of this chloride channel may also pave the way for better medical treatments, for example, after stroke. "In the case of damage in the brain, cells swell and release glutamate, which acts upon receptors on nerve cells. The subsequent inflow of calcium raises the intracellular concentration of this ion to toxic levels," Jentsch said. With the onset of programmed cell death (apoptosis) during cancer chemotherapy, however, there is a strong reduction in cell volume. The volume-regulated chloride channel also appears to be involved in this process.

Molecular Diagnostics Are Leading the Way to Personalized, Precision Medicine, Says Society for Women's Health Research

Contact Information

Available for logged-in reporters only

Newswise The Society for Womens Health Research (SWHR), the leading voice on research into the biological sex differences between women and men, is proud to announce a public awareness campaign focused on Transforming Science: Innovations in Molecular Diagnostics. SWHR launched the yearlong focus on this rapidly advancing field in womens health during the 2014 Annual Gala on April 2. More details at SWHR.org.

Diagnostics are an important part of every stage of health care, with 70 percent of medical decision-making influenced by these tests. Molecular diagnostics detect specific genetic sequences and proteins to help diagnose and monitor disease, assess risk for disease, and decide which treatments work best for individual patients.

At the gala, SWHR premiered an 8 -minute film highlighting the powerful impact of molecular diagnostics on womens health, including coronary artery disease, breast cancer, ovarian cancer, colorectal cancer, sexually transmitted diseases, and mental health. This will be the cornerstone of a national multimedia campaign that will include print, TV and radio public service announcements that highlight the benefits of molecular diagnostics for everyday women.

SWHR also will focus on the impact of molecular diagnostics at a series of events this year before the medical community, health care advocates and policymakers on Capitol Hill and the administration. On May 13, SWHR will host a Congressional briefing that will feature several presentations and speakers highlighting the advances in molecular diagnostics, particularly through the patient experience.

On September 12, SWHR will host a breakfast and panel discussion on molecular diagnostics at TEDMED in Washington, D.C. TEDMED is an annual conference that brings together leading innovators and investors from the global community who share an interest in science, medicine and research. The panel of nationally recognized experts will discuss various topics related to molecular diagnostics, including the history of the field, current and future innovations, and the value of molecular diagnostics in medicine and health care.

The Society for Womens Health Research is the national leader in advocating for greater understanding into how diseases and conditions affect women and men differently. SWHR believes in the promise of molecular diagnostics and its ability to shape the future of health care for men and women alike, said Phyllis Greenberger, SWHR president and CEO. Molecular diagnostics are changing the way we diagnose and treat disease, and are helping health care professionals make individualized, more effective medical decisions for patients. These revolutionary tests are leading the way to personalized, precision medicine.

Researchers Identify Achilles Heel Of Malignant Tumor Cells

By Estel Grace Masangkay

A study conducted by researchers from the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences has identified the enzyme MTH1 as the Achilles Heel of malignant tumor cells. The vulnerability could be explored as a potential novel antitumor therapeutic approach.

In addition, researchers have also discovered the chemical mirror image of crizotinib, an existing anti-cancer drug, to be effective at inhibiting MTH1 activity. Findings from the study show that malignant tumor cells are vulnerable to imbalances in nucleotide metabolism. The research was conducted by the researchers from Vienna in collaboration with colleagues from Oxford and Stockholm.

This paper represents a creative and original application of pharmacology, signal transduction biochemistry, and structural biology employed to make inroads into the therapy of cancers that have to date resisted effective treatment, said Robert A. Weinberg, founding member of the Whitehead Institute for Biomedical Research, Professor of Biology at MIT in Cambridge, USA.

The researchers were able to demonstrate that MTH1 targeting drugs selectively induce DNA damage in cancer cells. The investigational anti-MTH1 drugs were also able to impair growth of aggressive, difficult to treat human tumors in model systems. MTH1 therefore, presents a therapeutic target that could herald a breakthrough in cancer therapy.

Scientific Director Giulio Superti-Furga, CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences, said, The elucidation of the mode of action of drugs is one of the greatest strengths of CeMM, whose expertise and technology assets are world-class in this area. Without the support of public funding for basic research this first breakthrough would not have been possible, and therefore we are grateful to the taxpayers. However, the next challenges will be costly, and it would be a shame if we had to give up at this point in time. Therefore, we depend on a solid funding base and are, in addition, also seeking additional sponsors, philanthropists, organizations, and partners, who share our vision of a fight against diseases through innovative research, and who are interested in a continuation of our research.

The study was published online by the scientific journal Nature earlier this month.
