FIGURE 3.
Three transcription factors EGR1, NFκB and STAT3 regulate miRNAs related to all four hyperlipidemia-related diseases. (A) Based on miRNAs found in Figure 2, experimentally verified transcription factors increasing their expression were collected and those regulating more than one miRNA gene from each single and co-morbid disease cluster are shown. The diagram shows EGR1, NFκB, and STAT3 regulate miRNAs in all four disease clusters. NAFLD, non-alcoholic fatty liver disease. T2DM/IR, type 2 diabetes mellitus/insulin resistance. (B) STAT3 and NFκB are key miR-155 and miR-221-regulating transcription factors. Manual publication search and database mining approach show that pro-inflammatory transcription factors, STAT3 and NFκB, positively regulate the expression of miR-155 and miR-221.
