Gene signature can predict who will survive chemotherapy
Apr. 16, 2013 An eight gene 'signature' can predict length of relapse-free survival after chemotherapy, finds new research in Biomed Central's open access journal BMC Medicine.
Researchers from Academia Sinica and the National Taiwan University College of Medicine first identified genes that were involved in cellular invasion, a property of many cancer cells, using the National Cancer Institute's 60 human cancer cell line panel (NCI-60). Comparing the pattern of activation of each of these genes in different cell lines with how these cell lines responded to 99 different anti-cancer drugs, helped narrow down the list of genes to just those which could potentially influence the outcome of chemotherapy.
Testing this link, Prof Ker-Chau Li, from Academia Sinica and UCLA, commented, "Our study found eight genes which were involved in invasion, and the relative activation of these genes correlated to chemotherapy outcome, including the receptor for growth factor EGF. We also found that some invasion genes had unique patterns of expression that reflect the differential cell responses to each of the chemotherapy agents -- five drugs (paclitaxel, docetaxel, erlotinib, everolimus and dasatinib) had the greatest effect."
When the researchers looked at gene expression data of these eight genes from cancer cell lines they found that there was an obvious difference between cells which responded to chemotherapy and those who did not (albeit with some overlap). In clinical studies, looking at lung and breast cancer, the patients, whose gene signature put them in the low-risk group, had a longer relapse free survival than the high-risk group.
Prof Pan-Chyr Yang of National Taiwan University added, "The discovery of prognostic biomarkers for chemotherapy patients remains critical toward improving the efficacy of cancer treatment. The eight-gene signature obtained here may help choice of treatment as part of individualized cancer therapy and our method of gene discovery may be applicable in studying other cancers."

4 Ways the Gene Patent Ruling Affects You
The Supreme Court is due to rule by the end of June on the landmark question of whether companies have the right to patent genes.
One party in the case isMyriad Genetics, a company that by 1998 had patented two genes strongly linked to breast and ovarian cancer risk, called BRCA1 and BRCA2.
Since then, thousands of genes have been patented.
Opponents argue that genes are products of nature, which cannot be patented. Myriad counters that when researchers "discover" genes and patent them, these genes are isolated from the human genome, and therefore can be patented. The benefits that patents bring (a temporary market monopoly) provide incentive and funding for researchers to "discover" genes in the first place, Myriad says.
A big concern about gene patents is that they hinder genetic research once one company has patented a gene, other researchers may fear infringing on that patent by conduct further research on it, the argument goes. But outside the world of research, the ruling will also have effects on patients, critics argue. Here are four effects of gene patents on patients:
Access to genetic testing
Some say gene patents restrict access to genetic testing, and in some cases, prevent patients from being tested at all. For instance, because Myriad owns the patents on BRCA1 and BRCA2, women who want to be tested for mutations in these genes must use the Myriad test, which costs about $3,000 and is not always covered by insurance.
If for some reason a company that owns a gene patent stops providing the test for it, patients may not be able to get the test at all. For instance, although the University of Utah Research Foundation patented a gene linked with the condition Long QT syndrome, it was not able to offer a test for the condition for a two-year period, according to a 2009 brief filed by the American Medical Association in support of the plaintiff in the gene patent case. (Long QT syndrome is a heart condition that can cause irregular heartbeats, and in some cases, sudden death.) In that period, other labs were prohibited from offering the test, and at least one person died from undiagnosed Long QT syndrome, the brief says.
Getting a second opinion
Myriad's patents on BRCA1 and BRCA2 have prevented patients from getting a second opinion about their test results, critics argue. For instance, a plaintiff in the Supreme Court case, Ellen T. Matloff of Yale Cancer Center, said that in 2006 she knew of a patient who had had breast and ovarian cancer who tested negative for BRCA1 and BRCA2, suggesting that this patient's cancers were not the result of a hereditary condition, according to the New York Times.
Supreme Court considers gene patents
The Supreme Court on Monday seemed skeptical that a human gene can be patented but also worried about what a decision to bar such patents would mean for private scientific inquiry and research.
Even the normally confident justices expressed some trepidation as they considered the complexities of patent law and the mysteries of biochemistry. They talked about the introns and exons that are parts of genes, but spent more time on simpler illustrations: baseball bats, a hypothetical plant in the Amazon with miraculous powers, the recipe for chocolate-chip cookies.
The justices caution is warranted: The decision could shape the future of medical and genetic research and have profound effects on pharmaceuticals and genetically modified crops.
The court is considering a challenge to a decision to award a patent to Myriad Genetics for isolating human genes that indicate a hereditary disposition to breast and ovarian cancer. Doctors and patients must use the diagnostic test that Myriad has developed, and others are restricted from research in that area.
The patents are being challenged by organizations of physicians and researchers, geneticists, patients and others who say that the snippets of DNA are products of nature and may not be patented, even though the U.S. Patent and Trademark Office has issued such patents for decades.
The challengers were represented by Christopher A. Hansen of the American Civil Liberties Union. He told the court that Myriad did not deserve a patent because it did not invent anything.
The genes themselves ... where they start and stop, what they do, what they are made of, and what happens when they go wrong are all decisions that were made by nature, not by Myriad, Hansen said.
Now, Myriad deserves credit for having unlocked these secrets. Myriad does not deserve a patent for it.
The justices did not so much disagree with Hansen as they did worry about the consequences of not rewarding companies that invest so much money in genetic discoveries.
What does Myriad get out of this deal? asked Justice Elena Kagan. Why shouldnt we worry that Myriad or companies like it will just say, Well, you know, were not going to do this work anymore?

New Rochelle, NY, April 16, 2013Interferons have antitumor activity and have been used to treat a variety of malignancies, including colorectal and ovarian cancers. However, their effectiveness varies. A clearer understanding of the role of interferon in immune-mediated tumor cell death and how its antitumor effects could be optimized are presented in a comprehensive Review article published in Journal of Interferon & Cytokine Research, a peer-reviewed publication from Mary Ann Liebert, Inc., publishers. The article is available free online on the Journal of Interferon & Cytokine Research website.
In the article "Immunomodulatory Effects of Interferons in Malignancies," Joseph Bekisz, Yuki Sato, Chase Johnson, Syed Husain, Raj Puri, and Kathryn Zoon, from the National Institutes of Health and the U.S. Food and Drug Administration, Bethesda, MD, discuss the implications of recent study results using interferons to treat cancer. They explore the mechanisms of interferon signaling that lead to tumor cell death and propose strategies for enhancing the therapeutic, anti-cancer effects of interferon. The authors also suggest directions for future research, including alternative methods of delivering interferon-activated immune cells.
"Interferon has long been used to treat certain types of cancer, but the mechanistic basis of successful therapy has remained elusive," says Co-Editor-in-Chief Ganes C. Sen, PhD, Chairman, Department of Molecular Genetics, Cleveland Clinic Foundation. "Here, the authors summarize results from a number of new investigations, helping to clarify our knowledge."

New Rochelle, NY, April 16, 2013Even as medical acupuncture is increasingly being validated as an effective treatment for a broad range of medical conditions, what has been missing is an understanding of the basic science and mechanisms of action of this age-old method of healing. A special issue of Medical Acupuncture, a peer-reviewed journal published by Mary Ann Liebert, Inc., publishers presents a series of articles by authors from around the world who provide diverse and insightful perspectives on the science and physiologic responses underlying medical acupuncture. The issue is available free on the Medical Acupuncture website at http://www.liebertpub.com/acu.
"Understanding acupuncture in the same manner that we understand the mechanism of action and pharmacokinetics of a particular drug will, similarly, enable us to match treatments better with conditions," states Guest Editor Richard F. Hobbs, III, MD. "The net effect will be improved outcomes," he writes in his editorial "Basic Science Matters."
In the editorial "Basic Science: Mysteries and Mechanisms of Acupuncture," Richard Niemtzow, MD, PhD, MPH, Editor-in-Chief of Medical Acupuncture, a retired Air Force Colonel and current Director of the USAF Acupuncture Center, Joint Base Andrews, Maryland, suggests that natural events have scientific explanations and that "the two explanationsone scientific, the other environmentalmight both elucidate how acupuncture works."
The issue includes a Review article by John Longhurst, MD, PhD, University of California, Irvine, entitled "Acupuncture's Cardiovascular Actions: A Mechanistic Perspective." The article describes how acupuncture's effects on cardiovascular function can decrease elevated blood pressure, improve blood flow, and relieve pain.
Steven Harte, PhD and colleagues from the University of Michigan (Ann Arbor) and Massachusetts General Hospital and Harvard Medical School (Boston, MA) report the results of a study aimed at understanding the differences in patient responses to traditional vs. sham acupuncture. They used pressure-pain testing to identify patients who may be less likely to respond to sham acupuncture based on levels of neurotransmitters in the brain. The study is described in the article "Pressure Pain Sensitivity and Insular Combined Glutamate and Glutamine (Glx) Are Associated with Subsequent Clinical Response to Sham But Not Traditional Acupuncture in Patients Who Have Chronic Pain."
Keith Spaulding, ND, MAc and coauthors assessed the electrophysiological differences between actual and nearby (or sham) acupuncture points in the article "Acupuncture Needle Stimulation Induces Changes in Bioelectric Potential."

Food For Thought – A Few Disadvantages of Genetic Engineering
April 16, 2013
Brett Smith for redOrbit.com Your Universe Online
While there are many advantages to the ability to modify genes, there are also a number of genetic engineering disadvantages. However, unlike the pros such as super-sized strawberries, drought-proof corn or fungus-resistant soybeans the cons of genetically engineered foods are sometimes a little harder to spot.
For starters, according to Washington Post columnist Dr. Peter Lind, genetically modified organisms (GMO) have proven inferior to their naturally occurring counterparts in terms of overall quality.
In every case of genetic engineered organisms, the product has been less naturally healthy overall than the original host organisms, he wrote in a March editorial. There may be a single trait that is superior, but the overall health of the organism is less than found in nature. From animals like the sheep Dolly, to the Flavr Savr tomato, to the products you are eating today and dont even know it, there are inherent problems consuming altered DNA.
Another of the principle genetic engineering disadvantages that Lind points out derives from the fact that DNA does not always fully break down during human digestion. This means that there is a chance that the bacteria in our intestines could incorporate parts of the genetically modified plants DNA such as the gene for super-resistance into their own, leading to new strains of super-bacteria.
Columnist Mark Bittman from the New York Times breaks down another unintended effect of genetic engineering in his recent column criticizing President Barack Obamas recent signing of the Monsanto Protection Act.
Monsanto has long been cited as being one of the biggest problems with genetic engineering. The agricultural company not only created a highly effective weed killer in RoundUp it also inadvertently engineered plants that are resistant to it. While RoundUp and the plants resistance to it have been a big financial hit for the company, they have also resulted in the emergence of several super weeds that are resistant to the herbicide.
Bittman argues that genetic engineering is a disadvantage in this case because after all the effort that went into developing the products and the extensive use of RoundUp which could have potentially leaked the stuff into the groundwater Monsanto and farmers have ended up right back where they started: fighting weeds.
According to the Times columnist, unnecessary waste is one of the biggest problems with genetic engineering, and the Monsanto Protection Act, which prevents the Department of Agriculture from stopping the production of GMOs once they are in the ground, only exacerbates the problem.

Name-brand genes: Is our genetic makeup what’s next in personal branding?
Posted at 07:53 AM ET, 04/16/2013
Apr 16, 2013 11:53 AM EDT
An American flag flies in front of the Supreme Court in Washington on June 27, 2012. (Alex Brandon - AP)
The Supreme Court heard arguments Monday in a case that could decide whether its possible to patent specific human genes that have been "snipped" out of our DNA and isolated in the laboratory. If the justices rule that Myriad Genetics can patent two human genes thought to be responsible for breast and ovarian cancer, we could be headed down a slippery genetic slope. A single corporation could own an essential part of what makes us human our genes and be able to use its patent monopoly to block other innovators from conducting research on specific fragments of our DNA.
According SCOTUS Blogs Amy Howe, the Justices appear to be leaning away from the position that specific human genes can be patented. One analogy the Court used was, as SCOTUS Blogs Lyle Denniston writes, "the leaf or sap of an Amazonian plant that has curative potentia l for human disease." Another analogy was the wooden baseball bat that has been shaped out of a tree limb. The plant growing in the Amazon cant be patented by researchers, just as the tree growing in the forest cant be patented by researchers. However, what can be patented is the process for extracting the sap from the plant or the actual product the baseball bat or medicine that is made from nature.
But heres where things get interesting: the Supreme Court, again according to Howes analysis, appears to have left open the door for corporations to patent complementary DNA (cDNA) synthetic DNA molecules that function the same as human DNA. (Justice Kennedy referred to these as "economy-class genes.") Using the analogies above, it would be like figuring out how to create a synthetic Amazonian plant or a synthetic Louisville Slugger tree in the laboratory an impressive feat of innovation worthy of a patent.
The undated handout photo shows the pipetting of a DNA solution, the typical thread structure of the DNA molecule. (Anonymous - ASSOCIATED PRESS) So, what if biotech corporations start creating synthetic genes that could be spliced into the human genome?
After all, if Myriad Genetics can patent the genes thought to be responsible for breast cancer and ovarian cancer, couldnt other companies patent synthetic genes responsible for things like superior athletic and physical performance? Since 1982, the U.S. Patent and Trademark Office (USPTO) has been handing out patents for human genes, which is how Myriad Genetics acquired its patents. Whats to stop the USPTO from handing out patents for synthetic genes as well?
Imagine a future where Nike peddles designer synthetic genes for, say, superior cardiovascular performance alongside its running and cycling gear, or Adidas sells designer genes for tallness alongside its new line of basketball shoes. It likely wouldnt stop there. When you think about the thousands of genetic markers that help to distinguish us from everyone else, its easy to see how the rise of synthetic designer genes would inevitably lead to the first designer baby. Parents in the future might not be able to resist a guarantee that their baby will have the right genes for beauty, brains, and longevity as well as even more specific characteristics.
Of course, there are a few caveats about designer synthetic genes. For one thing, its still extraordinarily difficult to determine which genes are actually responsible for specific traits and characteristics. You might sign up for one synthetic gene and get entirely different results than you expected. And, according to Myriad Genetics, its also extraordinarily expensive to create the genetic mapping process for extracting copies of genes found within the human body and isolating them within a laboratory environment. As the Supreme Court appears to realize, you dont engage in this activity unless theres a world of profit out there for the taking, which is what a patent monopoly on human genes would give you.

Genetic variation contributes to pulmonary fibrosis risk
Public release date: 15-Apr-2013 [ | E-mail | Share ]
Contact: Mark Couch mark.couch@ucdenver.edu 303-724-5377 University of Colorado Denver
AURORA, Colo. (April 15, 2013) A newly published study of patients with pulmonary fibrosis has discovered multiple genetic variations that should help with future efforts to treat the disease.
Pulmonary fibrosis is a condition where lung tissue becomes thickened, stiff and scarred. Currently in the United States, there are no drugs approved for use in cases of the condition's most common and severe form, which is known as idiopathic pulmonary fibrosis (IPF) because the cause of the disease is not known. In those cases, the median survival time after diagnosis is two to three years and lung transplants are the only intervention known to prolong life.
This new study found evidence that common genetic variation is an important contributor to the risk of developing IPF, accounting for approximately one-third of the risk of developing disease. The study identified seven novel genetic risk loci that include genes involved in host defense, cell-cell adhesion, and DNA repair. These findings suggest that the disease is primarily initiated by defects in the lung's ability to defend against internal and environmental challenges.
This international collaborative research was led by scientists at the University of Colorado.
"The insightful leadership of Tasha Fingerlin, extraordinary contributions of Elissa Murphy, and active participation of many others ensured the success of this research and, in aggregate, we have established the scientific basis for early recognition and have identified novel therapeutic targets for this untreatable disease," says David A. Schwartz, MD, chairman of the Department of Medicine at the University of Colorado School of Medicine and senior author of the study. "These findings will change the way we think about pulmonary fibrosis and should eventually enhance the diagnostic and therapeutic options for our patients."
Fingerlin, PhD, and Murphy, MS, also authors of the study, are researchers at the Colorado School of Public Health and the CU School of Medicine.
The study, published in the April 14 edition of the journal Nature Genetics, is the first study to map out genes associated with IPF risk on a genome-wide scale. Three previously known genetic links were confirmed and seven novel loci were identified by studying the entire genome in this progressive incurable disease.
The work was supported by the National Heart, Lung, and Blood Institute (NHLBI). "In addition to expanding the library of genetic changes that can underlie pulmonary fibrosis, this study's findings demonstrate that both rare and common genetic variants contribute significantly to pulmonary fibrosis risk," says James Kiley, PhD, Director of NHLBI's Division of Lung Diseases. "A key next step for research is figuring out how these genetic variants work with environmental factors in the development of the disease."

Atossa Genetics to Provide ForeCYTE Breast Health Test to Two Leading Breast Centers in Texas
SEATTLE, WA--(Marketwired - Apr 16, 2013) - Atossa Genetics, Inc. (NASDAQ: ATOS), The Breast Health Company, will soon begin providing its patented ForeCYTE Breast Health Test for early detection of precursors to breast cancer at two breast centers in Texas: Aurora Breast Center in San Antonio and The Breast Center at Wellness Lubbock in Lubbock. These two breast centers are the first comprehensive breast centers in Texas to offer the ForeCYTE test and represent an important step forward in the Company's quest to make the ForeCYTE test a standard of care nationwide.
The Aurora Breast Center is a leading comprehensive breast care center in San Antonio featuring cutting-edge breast imaging, biopsy and cancer treatment technology and The Breast Center at Wellness Lubbock offers a holistic approach to breast wellness intended to help prevent manageable disease from becoming life-threatening crises. Together, these two clinics serve approximately 5,000 patients annually.
"Dr. Jui-Lien 'Lillian' Chou, M.D., a board-certified radiation oncologist, and her teams in San Antonio and Lubbock know that early detection of precursors to breast cancer can mean the difference between life and death. The Atossa team hopes that other doctors and health centers will follow their lead and join in the crusade for earlier testing for the health and longevity benefit of our sisters, mothers, daughters, wives and friends," said Chris Destro, Vice President.
Dr. Chou, a breast cancer survivor, commented, "Finding and treating precancerous conditions and breast cancer as early as possible is vital. By offering the ForeCYTE Breast Health Test in San Antonio and Lubbock, we are providing women in these areas with a powerful new tool for maintaining their health."
Atossa Genetics' goal is to reduce the stubbornly high rate of breast cancer through the early detection and treatment of the precursor changes that lead to breast cancer. The traditional approach to breast cancer screening is to detect cancer. In addition to cancer detection, Atossa's ForeCYTE test looks earlier in the progression to cancer by detecting reversible, precancerous breast changes.
About the ForeCYTE Breast Health Test
The ForeCYTE Breast Health Test, intended for the 110 million women in the U.S. ages 18-73, is a painless, quick and non-invasive procedure that can be done in a physician's office. A small sample of fluid, aspirated from the nipple of each breast with the Company's patented breast pump, can provide vital early detection of cancer or pre-cancerous conditions that may progress to cancer over an approximately eight year period before cancer can be detected by mammography or other means. The ForeCYTE test is painless, uses no radiation, no invasive biopsy needles and surgical incisions.
Samples obtained by the ForeCYTE method are tested at Atossa's wholly owned National Reference Laboratory for Breast Health, a CLIA-certified high-complexity molecular diagnostic laboratory located in Seattle.
About Atossa Genetics, Inc.
Atossa Genetics, Inc. (NASDAQ: ATOS), The Breast Health Company, based in Seattle, WA, is focused on preventing breast cancer through the commercialization of patented, FDA-designated Class II diagnostic medical devices and patented, laboratory developed tests (LDT) that can detect precursors to breast cancer up to eight years before mammography.

Gene study helps understand pulmonary fibrosis

A new study looking at the genomes of more than 1,500 patients with idiopathic pulmonary fibrosis, a rare and devastating lung disease, found multiple genetic associations with the disease, including one gene variant that was linked to an increase in the risk of death.
The study, released early online in The Lancet Respiratory Medicine, showed that a variant in a gene called TOLLIP was associated with an increased mortality risk. That variant resulted in decreased expression of TOLLIP in the lungs of patients with idiopathic pulmonary fibrosis (IPF).
Because TOLLIP, also known as toll interacting protein, plays a role in regulating immunity to certain stimuli, this novel finding suggests that an abnormal immune response, possibly to infectious agents or even environmental injury, may be central to the disease.
Curiously, the version of TOLLIP that appears to prevent onset of the disease was also the variant that increased the risk of death in patients who did develop IPF.
"Our initial genome-wide study revealed 20 genetic loci that may be associated with this disease," said lead author Imre Noth, MD, professor of medicine and director of the Interstitial Lung Disease Program at the University of Chicago. "A more focused investigation showed that four of these play a crucial role."
The researchers confirmed one previously implicated gene tied to disease onset and, more important, found the new genetic locus that appears to play a role in both onset and mortality.
The results "change our perception of the importance of genetics in IPF," Noth said. "Preliminary work, looking at multiple variants of different genes, may allow us to predict the risk of death in IPF patients, which can vary according to their genetics up to 6.5 fold. This would be a powerful prognostic test."
Idiopathic pulmonary fibrosis affects about 150,000 people in the United States, usually after age 50. It causes progressive scarring of the lungs, which leads to increasing difficulty with breathing. For most patients, this leads to death, usually within three to five years. The only effective therapy is a lung transplant.

BEAT BioTherapeutics Corporation Closes $2.5MM Seed Financing to Develop Its Gene Therapy Treatment for Heart Failure
Will the Supreme Court end human gene patents after three decades?
Since the 1980s, patent lawyers have been claiming pieces of humanity's genetic code. The United States Patent and Trademark Office has granted thousands of gene patents. The Federal Circuit, the court that hears all patent appeals, has consistently ruled such patents are legal.
But the judicial winds have been shifting. The Supreme Court has never ruled on the legality of gene patents. And recently, the Supreme Court has grown increasingly skeptical of the Federal Circuit's patent-friendly jurisprudence.
Meanwhile, a growing number of researchers, health care providers, and public interest groups have raised concerns about the harms of gene patents. The American Civil Liberties Union estimates that more than 40 percent of genes are now patented. Those patents have created "patent thickets" that make it difficult for scientists to do genetic research and commercialize their results. Monopolies on genetic testing have raised prices and reduced patient options.
On Monday, the high court will hear arguments about whether to invalidate a Utah company's patents on two genes associated with breast cancer. But the legal challenge, spearheaded by the American Civil Liberties Union and the Public Patent Foundation, could have much broader implications. A decision could invalidate thousands of patents and free medical researchers and clinicians to practice medicine without interference from the patent system.
The ACLU has cast a Utah biotech company called Myriad Genetics as the villain in its campaign against gene patents. Almost two decades ago, the University of Utah (a defendant in the original lawsuit) sequenced two genes, called BRCA1 and BRCA2, that are associated with an elevated risk of breast cancer. The University patented their findings before eventually licensing them to Myriad. Since the company began using said patents, it has enjoyed a de facto monopoly over testing and research related to the genes. Currently, Myriad even has a monopoly on the implications of various genetic differences, though some people are trying to undercut that as well.
"When Myriad genetics began cracking down and closing labs, no one else could offer the test," said Ellen Matloff, a cancer genetic counselor in an ACLU-produced video. Researchers began to suspect that Myriad's test was giving false negatives for some mutations of the BRCA genes. But Matloff says that when she asked for permission to offer a supplemental test for patients who got a negative result from Myriad's test, she was told that doing so would violate Myriad's patent.
Kathleen Maxian, a woman with late stage ovarian cancer, believes that Myriad's patents may have prevented her from catching the disease soon enough to get a hysterectomy. A few years earlier, her sister was diagnosed with breast cancer and took Myriad's test to see if the cancer might have a genetic basis. Because her sister's test came up negative, Maxian chose not to get tested herself.
Myriad eventually offered Maxian's sister a more comprehensive test that showed her family had a genetic predisposition toward breast and ovarian cancer. But it was too late to help Maxian. She believes that without Myriad's patent restrictions, other labs would have offered a more comprehensive test earlier, potentially saving her life.
A fundamental principle of the Supreme Court's patent precedents is that only inventions, not discoveries of natural phenomena, are eligible for patent protection. In last year's Mayo v. Prometheusdecision,for example, the high court examined a patent that instructed doctors to adjust the dose of a drug based on the level of a particular chemical in the patient's blood. Justice Stephen Breyer, writing for a unanimous court, ruled that the patent was invalid because the patent effectively claimed ownership of a fact about human biology. The only "invention" consisted of "well-understood, routine, conventional activity" to measure the patient's blood chemistry.
The ACLU argues the same point applies to Myriad's gene patent. Myriad acknowledges that it can't patent genes while they're in the human body. But it argues that the BRCA genes become eligible for patent protection once they are "isolated" from the human body. But the ACLU counters that the differences between "natural" and "isolated" genes are not significant enough to make the latter a human invention rather than a mere discovery.

Will the Supreme Court end human gene patents after three decades?
Gene Patent Case Goes to High Court
After battling breast cancer in 2008, Lisbeth Ceriani took on a whole new challenge. She joined a lawsuit against a biotechnology company she believed was blocking her ability to make informed decisions about her ongoing treatment.
Myriad Genetics was awarded patents in the 1990s on two isolated genes called BRCA 1 and BRCA2 as well as diagnostic methods. Women with mutations in those genes are at a much higher risk for breast and ovarian cancer. Because of the patent, Myriad is the only place to go for testing, and it sets the $3,340 price tag.
Ceriani's problem was that even though her doctors recommended she get the test to make an informed decision about future risks (ovarian in particular) she could not afford it. She was stunned to learn that the patents give Myriad the right to prevent others from doing commercial testing.
"I think my genes are mine," she says. "Myriad thinks they are not mine."
On Monday, the Supreme Court will hear a challenge to Myriad's patents originally brought by scientists, researchers and patients who believe the patents stand in the way of further research on the genes and limit the availability of testing. The ACLU is representing the groups and argues that the Court should invalidate the patents because they cover a product of nature and not an actual invention.
The case has huge ramifications for biotechnology companies racing to create personalized tests and treatments tailored to a person's genetic make-up.
Myriad says that the patents have been essential to the development of diagnostic tools to help patients and doctors assess the risks of cancer. The company rejects the notion that it somehow owns someone's genes. "Each individual's DNA is theirs," says Mark Capone, the company's president. He says that what his scientists did was identify, define and isolate the genes out of the human body, which led to a momentous scientific advancement. The company says it spent over $500 million and that it took 17 years to recoup the capital investment. Without protection from a strong patent system, Myriad argues it won't have the incentive to charge ahead.
Capone says over one million women have been tested and that 95% of patients in the U.S. have access to the testing through private insurance and other coverage. "For the first time they have been given the opportunity to identify why these cancers have ravaged their family histories."
Dan L. Burk, a law professor at the University of California, Irvine, believes the Court should uphold Myriad's patents. "The patent doesn't cover anybody's genes in their body. The patent only covers isolated molecules that are outside the body. It is against patent office policy and against patent law to own a human being or anything in the human body."
But Sandra Park, a senior attorney with the ACLU, says, "The patents are framed as covering and claiming the isolated genes. What that means is that the moment the gene is removed from the cell, Myriad owns it. The scope of the patent is incredibly broad."

Gene Patent Case Goes to High Court
Supreme Court gene patent decision could affect every patient
By Brian Alexander, NBC News Contributor
The legal question at the heart of the US Supreme Courts debate over the patenting of human genes has practical ramifications that could ripple into the lives of every American -- not just women at risk for rare breast cancer.
Dorothy Warburton, Ph.D./Newscom
BRCA 2 (breast cancer) gene on chromosome 13.
What the high court decides could affect who will conduct your medical tests, how those tests are interpreted, how and how fast drugs can be developed -- and what your doctor can tell you about your health, experts say.
Thats because all of those issues are entangled in the case involving a Utah company, Myriad Genetics, which controls the patents on variations of two human genes, known as BRCA1 and BRCA2. Women with mutations in those genes are at much higher risk for getting breast and ovarian cancer.
This is important, says patent expert Arti Rai, the Elvin R. Latty professor of law at Duke University School of Law, and an affiliate of Dukes Institute for Genome Sciences and Policy. If the court rules against Myriad, this may make it easier for you to get second opinions, about diagnostic tests, she said.
Myriad owns the patents to the genetic sequences, as well as any mutations along those genes. The American Civil Liberties Union, which has brought the case on behalf of a coalition of patients, researchers and doctors, argues that that means that if genes from a particular person are analyzed or separated from other biological material, regardless of how or for what reason, that would constitute patent infringement.
The industry has countered for years -- and won on this argument -- that they don't patent the genes, but the man-made molecules based on those genes.
Myriads current exclusive right to the testing means all BRCA tests are conducted by Myriad. Theres no second opinion or confirmation by an independent second source and Myriad can set its own price free of competition.

Can new plasma-based biomaterials speed healing of injured tissues?
Public release date: 15-Apr-2013 [ | E-mail | Share ]

New Rochelle, NY, April 15, 2013Platelet-rich plasma (PRP) derived from blood contains growth factors and other bioactive molecules that promote healing at sites of tissue injury. However, it is difficult to deliver and retain these molecules at a target site, and clinical results have proven to be mixed until now. A new solid form of bioactive plasma-based biomaterials, known as PBMs, can accelerate tissue healing. Not only are PBMs easier to work with, inexpensive to produce, and safe to use, they are available as off-the-shelf products. All of these promising advantages, and the potential to use PBMs to enhance healing of difficult-to-treat connective tissue injuries affecting cartilage, tendons, and ligaments, contribute to their unique possibilities as described in the article "Biologically Active Blood Plasma-Based Biomaterials as a New Paradigm for Tissue Repair Therapies," by Smith et al. in Disruptive Science and Technology, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Disruptive Science and Technology website at http://www.disruptivescience.com.
Authors Jason Smith and Alan West, Carmell Therapeutics Corp.; Lee Weiss, Robotics Institute, and Phil Campbell, Institute for Complex Engineered Systems, Carnegie Mellon University; and James Burgess, Department of Neurosurgery, Allegheny General Hospital, Pittsburgh, PA, describe initial studies with PBMs in which they were successfully used to stimulate the repair of a bone defect in a mouse. They conclude that "PBM products have the potential to accelerate healing and reduce pain and complications, enabling patients to return to work and their daily lives more quickly." The authors further discuss the development of the PBM technology, its potential applications, advantages over existing treatment options, and the barriers still to be overcome for clinical implementation.
According to study author Alan West, "There has been much recent interest in the concept of using natural regenerative factors to heal wounds the use of autologous platelet-rich plasma is seeing wide-scale clinical use for treating musculoskeletal and other injuries. Our plasma-based biomaterials move this concept a quantum leap forward, with materials that have the potential to disrupt the industry with a new category of biologics that are inexpensive to produce, safe, and robust in healing both bone and soft tissue injuries."
"There is a significant need for effective, consistent, and cost effective products that can biologically enhance tissue healing," says Editor-in-Chief Alan J. Russell, PhD, Highmark Distinguished Professor, Carnegie Mellon University. "By being cost effective and readily available, PBMs can benefit a wide population of patients in healthcare systems. The research Smith and his colleagues have published has the potential to benefit not only the First World Countries, but also could be practical options for developing nations."

Mount Sinai study identifies new gene variations associated with heart rate
Public release date: 14-Apr-2013 [ | E-mail | Share ]

(New York, NY April 14, 2013) Through a collaborative genome-wide study on individuals, researchers have discovered 14 new genetic variations that are associated with heart rate. Since heart rate is a marker of cardiovascular health, these findings could provide a better understanding of genetic regulation of heart beat and is a first step towards identifying targets for new drugs to treat cardiovascular disease.
The study, titled, "Identification of Heart Rate-Associated Loci and Their Effects on Cardiac Conduction and Rhythm Disorders," was published online this week in the April issue of Nature Genetics. Led by researchers at the Icahn School of Medicine at Mount Sinai and the Medical Research Council Epidemiology Unit in Cambridge, UK, the collaboration involved 268 researchers from 211 institutions, as well as six large research consortia joined forces.
In order to gain new insights into the genetic regulation of heart rate, Dr. Ruth Loos, Director of the Genetics of Obesity and Related Metabolic Traits Program at the Charles Bronfman Institute for Personalized Medicine at Mount Sinai and honorary investigator at the Medical Research Council Epidemiology Unit and her team, spent three years working on a genome-wide association study using data from 181,171 participants from 65 studies during 2009-2012. "Without any prior hypothesis, we studied the entire human genome hoping to identify new genetic variations that no one before had even imagined would play a role in the regulation of heart rate," said Dr. Loos, senior author of the study. "This discovery is just the beginning of something new and exciting and can hopefully be used to identify new drugs that can be used for the treatment of heart rhythm disorders."
In a follow-up study, experimental down-regulation of gene expression was then conducted on fruit flies and zebra fish, to better understand how genetic variations might affect heart rate. These experiments identified 20 genes with a role in heart rate regulation, signal transmission, embryonic development of the heart, as well as cardiac disorders, such as dilated cardiomyopathy, congenital heart failure and sudden heart failure. "Our findings in humans as well as in fruit flies and zebrafish provide new insights into mechanisms that regulate heart rate," said Dr. Marcel den Hoed, post-doctoral fellow at the Medical Research Council Epidemiology Unit and lead author of the study.
The follow-up study also showed that a genetic susceptibility for higher heart rate is associated with altered cardiac conduction and a reduced risk of sick sinus syndrome, a common indicator for pacemaker implantation. "Our study tripled the number of genetic variations that are known to be associated with heart rate, some of which are also associated with other cardiovascular risk factors and with heart rhythm disorder," said Dr. Loos.

Patents for human genes?
By Pete Williams, Justice Correspondent, NBC News
In a Supreme Court test of whether a company can be granted a patent on the genes in the human body, a majority of the justices indicated during Monday's oral arguments that the court is likely to rule that a human gene cant be patented.
It would be one thing, several of the justices said during Mondays oral arguments, for a company to seek a patent on a test for breast cancer that was developed by analyzing a human gene, but it would be going too far to be awarded a patent on the gene itself.
"What's the difference between snipping off a piece of the liver or kidney, and seeking a patent on that, and seeking a patent on a piece of a gene?" asked Justice Sonia Sotomayor.
Justice Samuel Alito made a different analogy, to someone seeking a patent on a plant found in the Amazon rain forest that bore leaves containing a cancer cure. "You could patent the process used to get the chemical out and the use of the result, but you cannot patent the plant," he said.

The case, Association for Molecular Pathology v. Myriad Genetics, involves a test that has helped guide more than a million women in their medical decisions. The test can determine whether the composition of their genes makes them more likely to get breast or ovarian cancer.
Myriad Genetics, a Utah company, owns patents on two parts of human genes known as BRCA 1 and BRCA 2, named for the first two letters of the words breast and cancer.
Women with mutations in those genes face up to an 85 percent risk of getting breast cancer and up to a 50 percent risk of ovarian cancer. Because of the patents, Myriad has a monopoly on performing all diagnostic tests related to BRCA 1 and BRCA 2.

Genetic hothouse celebrates 10 years
15 April 2013 Last updated at 12:30 ET
Breakthroughs in understanding how diseases like Alzheimer's and bowel cancer take hold have been highlights of 10 years of a Welsh genetic research "hothouse," says its head.
The Wales Gene Park is marking a decade of academic developments and turning research into treatments for the NHS.
Director Julian Sampson said Wales was recognised for its genetic research.
First Minister Carwyn Jones said the park's work was modernising the health service and improving future health.
The Wales Gene Park has bases at both Cardiff and Swansea universities.
One of the centre's achievements has been the development of a drug treatment for an inherited disorder known as tuberous sclerosis.
This causes multiple tumours to grow on the body's organs and in certain serious cases can be fatal.
The pace of technological developments is very quick
"Genetic research in Cardiff identified the gene that causes inherited tuberous sclerosis and we then worked out the functions of these genes," said Prof Sampson.
