miR-199a2, which targets HIF-1α mRNA, is localized in an intron of DNM3os. Transcription factor, PPARα, which regulates DNM3os transcription concordantly regulates miR-199a2 expression as miR-199a2 is located in the DNM3os transcription unit. In the schematic, Fenofibrate, a PPARα agonist, augments the transcription of DNM3os and miR-199a2. As a result of increased expression of miR-199a2, there is a decrease in HIF-1α levels and concomitantly of ET-1, indicating therapeutic potential of Fenofibrate in PH. Adapted and modified (73).
