Figure 2: Circulating levels of miR-15a, miR-223, and miR-126 in plasma samples of normal, T2DM-susceptible individuals, and diagnosed T2DM patients. qRT-PCR was performed with RNA extracted from plasma samples from 3 groups. (a) The heat-map depicts the expression of the 3 miRNAs in the 90 plasma samples. (b) The graph showed that relative plasma miRNAs.
