Figure 1. Hyperglycemia induced excessive miR-133a expression in ischemic muscle tissue and endothelial cells under simulated ischemia.
(A) Higher levels of miR-133a protein were expressed in day 7 postischemic gastrocnemius anterior (GA) muscle tissues from mice with type 1 DM compared with day 7 postischemic GA tissues from nondiabetic mice. (B) Cultured endothelial cells (HUVEC) exposed to high glucose culture (D25) showed higher level of miR-133a compared with HUVECs exposed to normal glucose (D5) 24 h under hypoxia and serum starvation conditions. Data = mean ± SEM; C56BL6, nondiabetic C57BL6 mice; DM, type 1 DM; **P<0.01.
