MicroRNA-302/367 cluster governs hESC self-renewal by dually regulating cell cycle and apoptosis pathways.

Zhang Z, Hong Y, Xiang D, Zhu P, Wu E, Li W, Mosenson J, Wu WS - Stem Cell Reports (2015)

Bottom Line: We demonstrate that in addition to its role in cell cycle regulation, miR-302/367 cluster conquers apoptosis by downregulating BNIP3L/Nix (a BH3-only proapoptotic factor) and upregulating BCL-xL expression.Furthermore, we show that butyrate, a natural compound, upregulates miR-302/367 cluster expression and alleviates hESCs from apoptosis induced by knockdown of miR-302/367 cluster.In summary, our findings provide new insights in molecular mechanisms of how miR-302/367 cluster regulates hESCs.
