MicroRNA-770 affects proliferation and cell cycle transition by directly targeting CDK8 in glioma

miR-770 is downregulated in glioma tissues and cell lines. a miR-770 expression was remarkably decreased in glioma tissues compared with that in adjacent normal tissues. b MiR-770 expression was significantly reduced in glioma cell lines (SNB19, LN229, U87 and U251) compared with that in normal human astrocyte (NHA) cells. *p？<？0.0
