New Knowledge of Genes Driving Bladder Cancer Points to Targeted Treatments

September 15, 2014 1:08 pm | News | Comments

The story of cancer care seems so simple: find the mutated gene that causes cancer and turn it off or fix it. But rarely does a single gene cause cancer. More often, many genes are altered together to drive the disease. So the challenge becomes sorting out which altered genes are the most to blame in which cancers. A new study takes an important step toward answering this question in bladder cancer.

Schizophrenia is Actually 8 Genetic Disorders

September 15, 2014 12:41 pm | News | Comments

New research shows that schizophrenia isn’t a single disease but a group of eight genetically distinct disorders, each with its own set of symptoms.                             

Study Links Genetic Mutation to Melanoma Progression

September 11, 2014 3:45 pm | News | Comments

Researchers have found that the genetic mutation BRAFV600E , frequently found in metastatic melanoma, not only secretes a protein that promotes the growth of melanoma tumor cells, but can also modify the network of normal cells around the tumor to support the disease's progression.

Mice and Men Share a Diabetes Gene

September 11, 2014 3:31 pm | News | Comments

A new study has identified a pathological process that takes place in both mice and humans towards one of the most common diseases that people face in the industrialized world: type 2 diabetes.                 

23andMe Navigates Health Regulation

September 11, 2014 10:35 am | by Matthew Perrone - AP Health Writer - Associated Press | News | Comments

Last November, the Food and Drug Administration ordered the company to stop marketing its personalized health reports, which purported to tell customers if they were genetically predisposed to more than 250 diseases and medical conditions. Now, 23andMe is working to win FDA clearance for its health tests one at a time.

Team Finds Ovarian Cancer Oncogene in 'Junk DNA'

September 9, 2014 3:43 pm | News | Comments

Over the years researchers have made tremendous strides in the understanding and treatment of cancer by searching genomes for links between genetic alterations and disease. Now, a team of researchers has mined "junk DNA" sequences to identify a non-protein-coding RNA whose expression is linked to ovarian cancer.
