Serum levels of miR-421 in diabetic patients and healthy controls. (A) miR-421 was significantly reduced in diabetic patients compared to healthy controls. (B) Declines in miR-421 levels were significant in diabetic patients with the presence and absence of complications. (C) miR-421 was significantly reduced in female diabetic patients compared to female healthy controls. (D) miR-421 levels were significantly altered in the different categories of healthy controls and diabetic patients depending on BMI. * indicates p < 0.05.
