DENVER & CHICAGO--(BUSINESS WIRE)--

The Global Down Syndrome Foundation, the Alzheimers Association, and the Linda Crnic Institute for Down Syndrome have awarded $1.2 million in research grants to five scientists for innovative investigations that explore the development of Alzheimers disease in individuals with Down syndrome. The goal is to eventually translate the findings into improved treatments for all people with Alzheimers.

The organizations are supporting this growing area of study through a new joint grants initiative called Understanding the Development and Devising Treatments for Alzheimers Disease in Individuals with Down Syndrome.

The Alzheimers Association is very interested in understanding why people with Down syndrome are at such high risk for Alzheimers, and how it relates to other variations of the disease, so that we can identify new therapies to treat Alzheimers in both the Down syndrome and typical populations, said Maria Carrillo, Ph.D., Alzheimers Association vice president of Medical and Scientific Relations. Research in this population may also help us develop predictive tools for Alzheimers and design more effective clinical trials.

Investing with the Alzheimers Association has been so rewarding. The science our joint initiative is funding is of the highest caliber, and each grant approaches understanding, treating or preventing Alzheimers in people with Down syndrome from a very different angle. If initial results are promising, we hope that the National Institutes of Health will continue to fund this excellent science, said Michelle Sie Whitten, executive director of the Global Down Syndrome Foundation.

Alzheimers Disease and Down Syndrome

Alzheimer's is a fatal, progressive, degenerative brain disease that causes problems with memory, thinking and behavior. More than 5 million Americans are living with Alzheimers, which is the sixth leading cause of death in the United States.

Down syndrome is a genetic disorder whereby a person has three copies of chromosome 21 instead of two. This chromosome also contains the gene that encodes the amyloid precursor protein (APP). APP is cleaved to form amyloid-beta, which is the primary component of amyloid plaques a lesion found in the brains of people with Alzheimers that many scientists believe is part of the cause of the disease.

According to the U.S. Centers for Disease Control and Prevention, Down syndrome occurs in 1 out of 691 infants in the United States. Due to improved clinical care, people with Down syndrome are now regularly living into their sixth decade of life, causing many to develop dementia due to Alzheimers. Autopsy studies show that by age 40, the brains of almost all individuals with Down syndrome have significant levels of plaques and tangles abnormal protein deposits that are considered Alzheimer's hallmarks. But despite the presence of these brain changes, not everyone with the syndrome develops Alzheimer's symptoms.

One of the many questions researchers hope to answer about Down syndrome is why some people develop dementia symptoms and others don't. Researchers are working to answer a similar key question about those who don't have Down syndrome. This may lead to new opportunities for treatment and prevention of the disease.

New Rochelle, NY, October 29, 2013Social media such as YouTube videos provide a popular and flexible venue for online activism. How two different social protest movementsOccupy Wall Street and the Proposition 8 same sex marriage initiativeutilized YouTube, and their success in engaging activists are explored in an article in Cyberpsychology, Behavior, and Social Networking, a peer-reviewed journal from Mary Ann Liebert, Inc., publishers. The article is available free on the Cyberpsychology, Behavior, and Social Networking website.

Emily Vraga, PhD and coauthors from George Mason University (Fairfax, VA), Georgetown University (Washington, DC), University of Wisconsin-Madison, and University of Southern California (Los Angeles, CA) emphasize an important advantage of YouTube videos for the purpose of social and political activism: they can be shared easily, quickly, and effectively through a variety of mechanisms, including other forms of social media, email, and print media.

The article "The Rules of Engagement: Comparing Two Social Protest Movements on YouTube" compares how two disparate political movements used YouTube to define and advance their goals. The study shows that social media activism resulted in differing degrees of popularity and engagement, perhaps related to the content of the videos and to the different online environments in which they appear.

"As YouTube matures, and additional social networking tools evolve, it is interesting to note how these tools may be used by individual citizens as well as political activists to advance their goals," says Brenda K. Wiederhold, PhD, MBA, BCIA, Editor-in-Chief of Cyberpsychology, Behavior, and Social Networking, from the Interactive Media Institute, San Diego, CA.

Charles P. Max Moehs is a principal scientist with Arcadia Biosciences in Seattle, where he uses both genetic engineering and conventional breeding to develop low-gluten grains and crops with increased stress tolerance.

Q: Why do you oppose labeling of genetically engineered foods?

A: Genetic engineering is a technology, not a trait. The National Academy of Sciences and other scientific bodies throughout the world have argued that the important thing about crops is what they contain, not how theyre generated.

If a food is unsafe, its not labeled; its taken off the market.

When you make soybean oil from soybeans genetically engineered to be resistant to an insect or herbicide, the oil doesnt contain any genetically engineered components. To add a label that says May contain genetically engineered ingredients is misleading and not really helpful to consumers.

Q: What do you worry might happen if GE foods are labeled?

A: I think it demonizes technology that has potential for a lot of benefits.

I also think it will require producers to segregate their genetically engineered and non-GE products ... and create an additional burden for them. Imagine trying to clean a combine of every last seed. If a farmer has both genetically engineered crops and non-GE crops, they would almost have to run two separate operations.

And it strikes me as an invitation to frivolous lawsuits.

Newswise New York, NYOctober 28, 2013: Researchers at Columbia Engineering, led by Chemical Engineering Professors Venkat Venkatasubramanian and Sanat Kumar, have developed a new approach to designing novel nanostructured materials through an inverse design framework using genetic algorithms. The study, published in the October 28 Early Online edition of Proceedings of the National Academy of Sciences (PNAS), is the first to demonstrate the application of this methodology to the design of self-assembled nanostructures, and shows the potential of machine learning and big data approaches embodied in the new Institute for Data Sciences and Engineering at Columbia.

Our framework can help speed up the materials discovery process, says Venkatasubramanian, Samuel Ruben-Peter G. Viele Professor of Engineering, and co-author of the paper. In a sense, we are leveraging how nature discovers new materialsthe Darwinian model of evolutionby suitably marrying it with computational methods. Its Darwin on steroids!

Using a genetic algorithm they developed, the researchers designed DNA-grafted particles that self-assembled into the crystalline structures they wanted. Theirs was an inverse way of doing research. In conventional research, colloidal particles grafted with single-stranded DNA are allowed to self-assemble, and then the resulting crystal structures are examined. Although this Edisonian approach is useful for a posteriori understanding of the factors that govern assembly, notes Kumar, Chemical Engineering Department Chair and the studys co-author, it doesnt allow us to a priori design these materials into desired structures. Our study addresses this design issue and presents an evolutionary optimization approach that was not only able to reproduce the original phase diagram detailing regions of known crystals, but also to elucidate previously unobserved structures.

The researchers are using big data concepts and techniques to discover and design new nanomaterialsa priority area under the White Houses Materials Genome Initiativeusing a methodology that will revolutionize materials design, impacting a broad range of products that affect our daily lives, from drugs and agricultural chemicals such as pesticides or herbicides to fuel additives, paints and varnishes, and even personal care products such as shampoo.

This inverse design approach demonstrates the potential of machine learning and algorithm engineering approaches to challenging problems in materials science, says Kathleen McKeown, director of the Institute for Data Sciences and Engineering and Henry and Gertrude Rothschild Professor of Computer Science. At the Institute, we are focused on pioneering such advances in a number problems of great practical importance in engineering.

Venkatasubramanian adds, Discovering and designing new advanced materials and formulations with desired properties is an important and challenging problem, encompassing a wide variety of products in industries addressing clean energy, national security, and human welfare. He points out that the traditional Edisonian trial-and-error discovery approach is time-consuming and costlyit can cause major delays in time-to-market as well as miss potential solutions. And the ever-increasing amount of high-throughput experimentation data, while a major modeling and informatics challenge, has also created opportunities for material design and discovery.

The researchers built upon their earlier work to develop what they call an evolutionary framework for the automated discovery of new materials. Venkatasubramanian proposed the design framework and analyzed the results, and Kumar developed the framework in the context of self-assembled nanomaterials. Babji Srinivasan, a postdoc with Venkatasubramanian and Kumar and now an assistant professor at IIT Gandhinagar, and Thi Vo, a PhD candidate at Columbia Engineering, carried out the computational research. The team collaborated with Oleg Gang and Yugang Zhang of Brookhaven National Laboratory, who carried out the supporting experiments.

The team plans to continue exploring the design space of potential ssDNA-grafted colloidal nanostructures, improving its forward models, and bring in more advanced machine learning techniques. We need a new paradigm that increases the idea flow, broadens the search horizon, and archives the knowledge from todays successes to accelerate those of tomorrow, says Venkatasubramanian.

Current ratings for: Red and processed meat 'increases colorectal cancer risk'

Ratings require JavaScript to be enabled.

People with a common genetic variant who consume red or processed meat may increase their risk of colorectal cancer. This is according to a study presented at the annual American Society of Human Genetics 2013 meeting.

Furthermore, the US researchers say they also found another specific genetic variant that suggests eating more fruit, vegetables and fiber may lower the risk of colorectal cancer.

To reach their findings, the researchers analyzed 9,287 patients suffering from colorectal cancer alongside a control group of 9,117 healthy individuals.

They also analyzed 2.7 million genetic sequences to determine whether there was a link between consumption of red and processed meat and colorectal cancer.

The study shows that individuals with the genetic variant rs4143094 - a variant that affects 1 in 3 people - demonstrate a significantly increased risk of colorectal cancer linked to the consumption of red and processed meat.

The researchers explain that this genetic variant is located on the same chromosome 10 region that has a transcription factor gene called GATA3 - a gene that has previously been linked to many forms of cancer.

The transcription factor encoded by this gene usually plays a part in the immune system, say the researchers.

Speculating on the link with processed meat, the researchers say that when the body digests it, this may trigger an "immunological or inflammatory" response. But if the GATA3 gene region consists of a genetic variant, it is possible it could encode a dysregulated transcription factor, making it hard to overthrow the response.

SALT LAKE CITY, Oct. 29, 2013 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (MYGN) today announced that it has launched a new prognostic test, Myriad myPlan Lung Cancer, for patients diagnosed with early-stage lung adenocarcinoma. myPlan Lung Cancer is an RNA expression panel of 31 cell-cycle-progression genes, in combination with tumor staging information, to determine a patient's risk of dying from lung cancer within five years.

The myPlan Lung Cancer test has been extensively studied in more than 1,500 patients. In these studies, myPlan Lung Cancer was shown to be significantly predictive of five-year lung cancer mortality and considerably more predictive than tumor staging information alone. In a large validation study presented at the IASLC annual meeting, patients with a high-risk myPlan Lung Cancer score had nearly twice the rate of lung cancer deaths (35 percent) than patients with a low-risk score (18 percent). These findings build on data published in Clinical Cancer Research that showed the myPlan Lung Cancer test is the strongest independent predictor of survival in patients with early-stage lung cancer as compared to the conventional clinical variables of disease progression including age, stage of disease, gender, smoking status and tumor size.

"Post-surgical treatment decisions for early-stage lung cancer patients are largely guided by tumor staging. However, the prognostic power of tumor stage alone is limited and there remain unacceptably high mortality rates for this patient population," said Mark C. Capone, president of Myriad Genetics Laboratories. "Myriad myPlan Lung Cancer is a powerful new prognostic test that stratifies patients based on their risk of lung cancer-related, five-year mortality. Our test will empower physicians to know with confidence which patients should receive surgery alone versus those who may need more aggressive therapy."

Myriad myPlan Lung Cancer is being launched in a phased approach beginning with an early-access, clinical-experience program to medical and scientific thought leaders, followed by a full commercial launch in calendar year 2014. myPlan Lung Cancer will be sold through Myriad's own specialty sales force to assist physicians in providing their lung cancer patients with the most appropriate healthcare management. myPlan Lung Cancer has a list price of $3,400.

Myriad myPlan Lung Cancer is the second molecular diagnostic test launched by Myriad this fiscal year. In September, the Company launched Myriad myRisk(TM) Hereditary Cancer, a new multi-gene diagnostic test for eight major hereditary cancers including breast, colorectal, ovarian, endometrial, pancreatic, prostate, gastric and melanoma.

Bolton, UK (PRWEB UK) 29 October 2013

According to the BBC, the University Hospital in Birmingham are trialing a new gene therapy hospital treatment, aiding in the fight against prostate cancer (1). The pioneering treatment could help prevent the incidence of surgical errors, increasing the success rate associated with treating the disease.

It is believed, that if the treatment works, surgery for prostate cancer will become a thing of the past, eliminating the surgical errors associated with the procedure.

According to the BBC, the University Hospital in Birmingham is among the first to trial the new treatment, stimulating the bodys own immune system to attack the tumor (1). With studies on mice showing complete eradication of the cancer, hopes are high for the imminent human trials.

A new form of gene therapy, the treatment requires a virus to be injected directly into the prostate cancer tumour; a gene attached to the virus (GM-CSF,) is then released, activating the body's own immune system, attracting white blood cells to attack the cancer (1). As reported by the BBC, the virus also carries an enzyme - nitroreductase - which sits inside the cancer cell.

Two days after the injection, the patient in question will be put on a drip, which contains a cancer drug (CB1954), which is initially inactive. When the drug comes into contact with the enzyme, it reacts and starts killing the cancer cells. The inactive drug, CB1954, does not harm cells which do not have the enzyme inside, protecting the healthy tissue surrounding the tumour (1).

Urology Specialist, Prashant Patel, is hopeful that gene therapy could provide real hope for patients who are running out of treatment options (1).

"I have to stress that this is only a phase one safety trial to test that there are no side effects. However, we are excited by this."

"If this works, 15 to 20 years from now, we could be using the patient's own immune system in this way to fight early onset prostate cancer so that patients won't need painful treatments or even surgery."

Newswise Scientists in The Research Institute at Nationwide Childrens Hospital have found a way to overcome one of the biggest obstacles to using viruses to deliver therapeutic genes: how to keep the immune system from neutralizing the virus before it can deliver its genetic payload. In a study published recently in Molecular Therapy, researchers found that giving subjects a treatment to temporarily rid the body of antibodies provides the virus safe passage to targeted cells, allowing it to release a corrective or replacement gene to treat disease.

Gene therapy is among the most promising treatment options for such genetic disorders as muscular dystrophy, congenital blindness and hemophilia. Scientists also are investigating gene therapy as a cure for some cancers, neurodegenerative diseases, viral infections and other acquired illnesses. To get the therapeutic gene into cells, researchers have turned to viruses, which deliver their genetic material into cells as part of their normal replication process. Time and time again, these efforts have been thwarted by the bodys own immune system, which attacks the viral vector. The therapeutic genes arent delivered and disease rages on.

Now, a team led by Louis G. Chicoine, MD, Louise Rodino-Klapac, PhD, and Jerry R. Mendell, MD, principal investigators in the Center for Gene Therapy at Nationwide Childrens, has shown for the first time that using a process called plasmapheresis just before delivering a virus-packed gene therapy protects the virus long enough for it to enter the cell and deliver the gene.

Plasmapheresis, widely used to treat patients with autoimmune disorders, removes blood from the body, separates the plasma and cells, filters out antibodies, and returns the blood to the patient. The antibody loss is temporary; the body begins producing new antibodies within a few hours of the procedure.

In a study of a gene therapy designed to treat Duchenne muscular dystrophy (DMD), Drs. Chicoine and Rodino-Klapac used plasmapheresis in a large animal model, then injected a virus packed with a micro-dystrophin gene. When they examined the levels of micro-dystrophin gene expression in the animals, they found a 500 percent percent increase over gene expression in animals that did not receive plasmapheresis. Dr. Mendell, director of the Center for Gene Therapy, helped conceive of this treatment for DMD patients based on experience with autoimmune diseases such as myasthenia gravis and inflammatory nerve diseases.

Right now, gene therapy seems to work best in patients who have no antibodies for the virus being used to deliver the gene, Dr. Mendell says. That limits the number of patients who can benefit from gene therapy.

Using plasmapheresis would increase the potential for gene therapy, Dr. Chicoine adds, by eliminating one obstacle of immune reaction.

As gene therapy becomes more prevalent, patients may need to receive more than one treatment, Dr. Rodino-Klapac says. The problem is that when they get the first treatment, their body will develop antibodies to the virus used to deliver the gene. Using plasmapheresis on someone who previously received gene therapy could allow them to be treated again.

THURSDAY, Oct. 24 (HealthDay News) -- Obesity is on the rise among children, and a particular genetic mutation might play a role for some kids, a new study suggests.

Researchers in Britain conducted genetic analyses of more than 2,100 severely obese youngsters. They found that those with mutations in the KSR2 gene had larger appetites and slower metabolism than those with a normal copy of the gene, according to the study published in the Oct. 24 issue of the journal Cell.

"Changes in diet and levels of physical activity underlie the recent increase in obesity; however, some people gain weight more easily than others," study author Sadaf Farooqi, of the University of Cambridge, noted in a journal news release. "This variation between people is largely influenced by genetic factors. The discovery of a new obesity gene, KSR2, demonstrates that genes can contribute to obesity by reducing metabolic rate -- how well the body burns calories."

The findings could someday lead to new treatments for obesity and type 2 diabetes, the researchers said.

Farooqi and colleagues had previously found that deleting the KSR2 gene led to obesity in mice, highlighting the gene's role in controlling energy balance and metabolism. These findings confirm KSR2's role in the regulation of weight and metabolism in humans.

"This work adds to a growing body of evidence that genes play a major role in influencing a person's weight and may be useful for developing new ways to treat people who are heavy and develop diabetes," Farooqi said.

A rare childhood disease may hold clues to treating Alzheimer's and Parkinson's, a study has found.

Scientists analysing A-T disease, which leaves youngsters unable to walk by adolescence, have found new ways of understanding the more common neurodegenerative diseases, according to the report in the online journal Nature Neuroscience.

Children born with A-T have mutations in both of their copies of the ATM gene and cannot make normal ATM protein, and experts at Rutgers University in New Jersey in the US hope their research will lead to new therapies for Alzheimer's and Parkinson's.

The rare genetic childhood disorder - which occurs in about one in 40,000 births - leads to problems in movement, co-ordination, equilibrium and muscle control as well as a number of other deficiencies outside the nervous system.

Using mouse and human brain tissue studies, the researchers from Rutgers found that without ATM, the levels of a regulatory protein known as EZH2 go up.

Looking through the characteristics of A-T disease in cells in tissue culture and in brain samples from both humans and mice with ATM mutation, they found that the increase in EZH2 was a major contributing factor to the neuromuscular problems caused by A-T.

SALT LAKE CITY, Oct. 28, 2013 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (MYGN) today announced that validation data for the Myriad myPlan Lung Cancer test showed that it significantly predicted patients' risk of death from early-stage lung adenocarcinoma within five years of being diagnosed. A key finding of the validation study is that patients with a high-risk myPlan prognostic score had approximately twice the number of lung cancer related deaths compared to patients with a low-risk score.

Myriad is presenting these results and another myPlan clinical study this week at the International Association for the Study of Lung Cancer (IASLC) 15th World Conference on Lung Cancer in Sydney, Australia. myPlan Lung Cancer is the only prognostic test on the market today that can assess a patient's risk of lung cancer mortality and thereby guide the physician in determining which patients may benefit from post-surgical chemotherapy.

"The Myriad myPlan Lung Cancer test provides new information that can identify people at high risk of lung cancer recurrence and will enable us to offer these patients additional therapy to improve their survival," said Raphael Bueno, M.D., Associate Chief of Thoracic Surgery at Brigham and Women's Hospital and Harvard Medical School. "Once we know a patient's risk profile, we can align our clinical management strategies to achieve better medical outcomes and save more lives."

The two studies being presented at the IASLC annual meeting are:

Validation of a Proliferation-based Expression Signature as Prognostic Marker in Early Stage Lung Adenocarcinoma. [Bueno et al., Poster: Oct. 28, 2013, 3:30 p.m. -- 4:15 p.m. AEDT]

This study evaluated the association of cell cycle progression (CCP) genes with five-year lung cancer mortality in 650 patients diagnosed with stage 1 or 2 lung adenocarcinoma. In this clinical validation study, patients with a high-risk Myriad myPlan Lung Cancer prognostic score had a significantly higher average five-year mortality rate (35 percent) than patients with a low-risk score (18 percent). The prognostic score (CCP + tumor stage) segregated stage 1A to 2B patients with five-year risk estimates ranging from 11 percent to 68 percent. This study demonstrated that the myPlan Lung Cancer prognostic score was statistically significant in predicting five-year lung cancer mortality, and was significantly more predictive than tumor staging information alone. These data strongly support the use of the Myriad myPlan Lung Cancer test to help stratify patients' risk profiles and determine which patients are candidates for conservative management with surgery alone versus more intensive therapy based on a higher personal risk profile.

Integrated Prognosis in Early-Stage Resectable Lung Adenocarcinoma. [Kim et al., Poster: Oct. 30, 2013, 3:30 p.m. -- 4:15 p.m. AEDT]

This study evaluated a prognostic model that combines a cell cycle progression (CCP) score with tumor stage in order to maximize the prognostic utility of both predictive markers. The primary outcome measure was cancer specific death within five years of surgery. The results for this study show that both tumor stage and CCP score are statistically significant independent predictors of lung cancer death. However, the combination of tumor stage and the CCP expression score was a more powerful predictor of post-surgical risk of cancer-specific death than tumor stage alone. Myriad myPlan Lung Cancer is a prognostic test that combines CCP score and tumor stage and offers clinicians a more precise risk assessment of patients with early-stage lung cancer, which may improve medical management of these patients.

CAMBRIDGE, Mass.--(BUSINESS WIRE)--

bluebird bio, Inc. (BLUE) a clinical-stage company committed to developing potentially transformative gene therapies for severe genetic and orphan diseases, today announced that the first subject in its phase 2/3 childhood cerebral adrenoleukodystrophy (CCALD) study, Starbeam (ALD-102) has undergone infusion with bluebird bios Lenti-D drug product in an autologous hematopoietic stem cell transplantation.

Treating our first subject in this study reflects the recent advances in the field of gene therapy and is the culmination of years of collaborative effort between the team at Dana-Farber/Boston Childrens Cancer and Blood Disorders Center and our colleagues at Massachusetts General Hospital, INSERM in Paris, and bluebird bio, stated David A. Williams, MD, Chief of hematology/oncology at Boston Childrens Hospital and Associate Chairman of pediatric oncology at Dana-Farber Cancer Institute. Boys with CCALD face significant risks of mortality and morbidity with allogeneic stem cell transplantation, the current standard of care treatment, if an optimally matched donor cannot be identified. bluebirds autologous Lenti-D drug product has the potential to circumvent this challenge and address an important unmet medical need for patients with this devastating disease.

Successfully initiating treatment in the Starbeam study represents an important step towards improving outcomes for patients with CCALD and is a major milestone for bluebird and its lentiviral gene therapy platform, stated Dave Davidson, MD, bluebird bios Chief Medical Officer.

About the Starbeam study (ALD-102)

The phase 2/3 study is designed to evaluate the safety and efficacy of Lenti-D drug product in the treatment of subjects with childhood cerebral adrenoleukodystrophy, or CCALD, a rare, hereditary neurological disorder affecting young boys that is often fatal. The trial study is planned to enroll up to 15 boys who will be followed for 24 months following a transplant with bluebird bios lentiviral transduced stem cells, Lenti-D. During this 24 month period, patients will be assessed for the onset of major functional disabilities, and other key assessments of disease progression.

For more information please contact clinicaltrials@bluebirdbio.com.

About Childhood Cerebral Adrenoleukodystrophy (CCALD)

Childhood Cerebral Adrenoleukodystrophy is an X-linked disease caused by the aberrant expression of the ABCD1 gene in boys leading to the inability of patients to metabolize very long chain fatty acids in cells of the brain. The disease is characterized by progressive destruction of myelin, leading to severe loss of neurological function and eventual death. The worldwide incidence of adrenoleukodystrophy (ALD) is approximately one in 20,000 newborns. CCALD accounts for about 30-40% of patients diagnosed with ALD.
