Stem cells improve visual function in blind mice

An experimental treatment for blindness, developed from a patient's skin cells, improved the vision of blind mice in a study conducted by Columbia ophthalmologists and stem cell researchers.

Gene mutation can allow proteins to gather, spark tumor growth

Prostate cancer is generally treated as if it's a single disease. But researchers have discovered a new type of the cancer that appears to affect 15 percent of patients, a finding that paves the way for better diagnosis and ...

Scientists unravel role of fusion gene in prostate cancer

Up to half of all prostate cancer cells have a chromosomal rearrangement that results in a new "fusion" gene and formation of its unique protein -- but no one has known how that alteration promotes cancer growth. Now, Weill ...

Study identifies target for diabetes drug

New research from the University of Cincinnati (UC) points to the naturally produced protein apolipoprotein A-IV (apoA-IV) as a potential target for a new diabetes therapeutic.

Genetics

Distinct molecular subtype of prostate cancer identified

A collaborative expedition into the deep genetics of prostate cancer has uncovered a distinct subtype of the disease, one that appears to account for up to 15 percent of all cases, say researchers at Weill Cornell Medical ...

Sensing self and non-self: New research into immune tolerance

At the most basic level, the immune system must distinguish self from non-self, that is, it must discriminate between the molecular signatures of invading pathogens (non-self antigens) and cellular constituents that usually ...
