Diosgenin glucoside protects against myocardial injury in diabetic mice by inhibiting RIP140 signaling.

Myocardial injury is often observed during diabetes, but the nature physiological association is unclear. Here, we investigated the protective effective of diosgenin glucoside (DG), a pharmacologically active saponin extracted from , against myocardial injury in type 2 diabetic (db/db) mice and its molecular mechanism of action. Levels of serum and myocardial tissues, blood glucose and inflammatory cytokines, as well as cardiac function indicators, of db/db mice were measured, and DG's mechanism of action was evaluated by immunohistochemistry and Western blotting.
