Los Angeles, California - National guidelines recommend that men with low- and intermediate-risk prostate cancer who have life expectancies of fewer than 10 years should not be treated with radiation or surgery, since they are unlikely to live long enough to benefit from treatment. Yet a new study by UCLA researchers found that more than half of such men are receiving these aggressive treatments putting them at risk for potentially debilitating side effects.

Los Angeles, California - A team of scientists that included researchers from UCLA has discovered a novel mechanism of RNA regulation in embryonic stem cells. The findings are strong evidence that a specific chemical modification, or “tag,” on RNA plays a key role in determining the ability of embryonic stem cells to adopt different cellular identities.

Los Angeles, California - In a study led by Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research member Dr. Julian Martinez-Agosto, UCLA scientists have shown that two genes not previously known to be involved with the immune system play a crucial role in how progenitor stem cells are activated to fight infection.

Imperial, California - People who know that certain foods are bad for them still respond positively when confronted by a picture of a burger, fries and soda, according to a University of California, Davis, study.

Davis, California - High-tech genomics and traditional Chinese medicine come together as researchers identify the genes responsible for the intense bitter taste of wild cucumbers. Taming this bitterness made cucumber, pumpkin and their relatives into popular foods, but the same compounds also have potential to treat cancer and diabetes.
