MedPage -- BIRMINGHAM, Ala., Sept. 30 -- The risk of colorectal cancer may be reduced by the presence of a genetic variation that also lowers adiponectin hormone secretion by fat cells, researchers found.

Medical News Today -- Experiments on lab cultured cells and mice suggested that high amounts of vitamin C derivative at the cellular level, as results from taking supplements, may actually reduce the effect of anti-cancer drugs by helping the cancer cells live longer.

EurekAlert -- Researchers have identified two new genes and confirmed the role of a third gene associated with increased risk of higher levels of uric acid in the blood, which can lead to gout, a common, painful form of arthritis. Combined, the three genetic variations were associated with up to a 40-fold increased risk in developing gout. The findings suggest that genetic testing could one day...
