RT-qPCR revealed that compared with healthy control, MAPK3 mRNA expression was obviously augmented in the peripheral blood of T2DM patients (Figure 6(a)), whereas miR-92a-2-5p expression was potently diminished (Figure 6(b)) and negatively correlated with MAPK3 expression (Figure 6(c)). This evidence concerns the gene MAPK3 and type 2 diabetes mellitus.
