MicroRNA-145 Promotes Human Endometrial Adenocarcinoma Cells Differentiation by Repressing OCT4

MicroRNA-145 (miR-145) has been reported to be a tumor-suppressing agent in several studies. It can repress pluripotency and control human embryonic stem cell differentiation by regulating the core pluripotency factor OCT4. However, it is not known whether miR-145 can play a role in inducing tumor cell differentiation and repressing growth of tumors. the established human endometrial cancer cells, Ishikawa cells, were treated with miR-145 mimics, inhibitor, or small interfering RNA OCT4. miR-145 levels were assayed using TaqMan microRNA assays, and the messenger RNA levels of OCT4 and the differentiation marker…
