Obesity treatments falter, but researchers announce gene links

The Wall Street Journal: "An international research consortium says it has identified 18 new gene sites linked to obesity and 13 others associated with how fat is distributed in the body, advances that shed new light on the complex biology underlying one of the world's most pressing public-health problems. The findings are based on studies involving nearly 250,000 people, making the effort the largest so far to unravel the genetic basis of common human traits, researchers said.

Geron commences GRNOPC1 hESC-based cell therapy in patients with spinal cord injury

Geron Corporation today announced the enrollment of the first patient in the company's clinical trial of human embryonic stem cell (hESC)-derived oligodendrocyte progenitor cells, GRNOPC1. The primary objective of this Phase I study is to assess the safety and tolerability of GRNOPC1 in patients with "complete" American Spinal Injury Association (ASIA) Impairment Scale grade A thoracic spinal cord injuries. Participants in the study must be newly injured and receive GRNOPC1 within 14 days of the injury.

Novel hormonal treatments may help ER-negative breast cancer patients: Study

Women who have estrogen (ER) negative breast cancer may have more drug treatment options than previously thought, a Creighton (pronounced Cray-ton) University study suggests. The study is reported in the Oct. 11 online version of the journal Oncogene.

Part of brain reorganizes to enhance visual abilities in deaf cats

Deaf or blind people often report enhanced abilities in their remaining senses, but up until now, no one has explained how and why that could be. Researchers at The University of Western Ontario, led by Stephen Lomber of The Centre for Brain and Mind have discovered there is a causal link between enhanced visual abilities and reorganization of the part of the brain that usually handles auditory input in congenitally deaf cats. The findings, published online in Nature Neuroscience, provide insight into the plasticity that may occur in the brains of deaf people.

New natural dietary components inhibit breast cancer cells

Researchers at Indiana University and Methodist Research Institute have published the dramatic effects of a natural formula against breast cancer. The impressive results are found in the most recent publication of Integrative Cancer Therapies. Lead investigator Dr. Daniel Sliva says, The formula we studied inhibits growth of highly metastatic human breast cancer cells, and suppresses metastatic potential of these cells.

Researchers develop new approach to treat inflammatory bowel disease

Researchers at the Georgia Institute of Technology and Emory University have developed a novel approach for delivering small bits of genetic material into the body to improve the treatment of inflammatory bowel diseases. Delivering short strands of RNA into cells has become a popular research area because of its potential therapeutic applications, but how to deliver them into targeted cells in a living organism has been an obstacle.

Study to uncover genetic basis of obesity

An international consortium has made significant inroads into uncovering the genetic basis of obesity by identifying 18 new gene sites associated with overall obesity and 13 that affect fat distribution. The studies include data from nearly a quarter of a million participants, the largest genetic investigation of human traits to date.

VBI researchers receive grant to study immune responses to gut pathogens

The National Institute of Allergy and Infectious Diseases, part of the National Institutes of Health, has awarded a $10.6 million grant to researchers at the Virginia Bioinformatics Institute (VBI) and collaborators to determine how the human immune system responds to infection by pathogens of the gut. The funding will be used to apply mathematical modeling to the study of immune responses to gut pathogens.

DTC genetic tests require innovative approach to enter global market

Direct-to-consumer (DTC) genetic tests available from retailers and the Internet let people learn about their genomes without going to a doctor, but they raise the question of who is responsible for oversight and regulation of these tests. Critics worry about safety risks if consumers base important lifestyle or medical decisions on inaccurate or misunderstood test results.
