Figure 4. Altered expression of miR-25, miR-92a and preproinsulin in diabetic rat pancreas. Total RNA was isolated from pancreatic tissue of diabetic rat model. Expression of miR-25, miR-92a, and insulin I was measured by qPCR relative to healthy control rats. Data are presented as mean ± SEM with n = 6. Statistically significant differences are tested using t-test at *p < 0.05 significance.
