According to the figure, several miRs induce apoptosis in granulosa cells by targeting different molecules and signaling pathways. miR-146a activates apoptosis by targeting TRAF 6. Downstream signaling of TRAF6 leads to the production of anti-apoptotic molecules such as survivin, XIAP, and cIAPs which are inhibitors of caspase 3 and 7. In another way, miR-146b can induce apoptosis by inhibiting DIAB2 expression. Mir23a by targeting SIRT1 leads to the activation of caspase 3 and apoptosis. miR-144 by targeting PTEN leads to the activation of MDM2 and FOXO, and apoptosis occurs. miR-15 leads to apoptosis by inhibiting SMAD4
