MiR-21 antagomir improves insulin resistance and lipid metabolism disorder in streptozotocin-induced type 2 diabetes mellitus rats.

Background: Type 2 diabetes mellitus (T2DM) is a major cause of death with an increasing incidence at an epidemic rate. The existing treatments for T2DM lack long-term effective blood glucose control. In this study, the effects of miR-21 antagomir on T2DM and the related mechanism were investigated using streptozotocin (STZ)-induced T2DM rats.
