TGen and USC researchers find genetic markers to help fight diabetes

...ensitivity. TZDs are a class of insulin-sensitizing drugs used to treat type 2 diabetes mellitus (T2DM). TZDs are agonists for the nuclear receptor peroxisome proliferator-activated receptor-g (PPARG). Although the exact mechanism by which TZDs act is not yet known, data indicate that TZDs improve insulin se...
