ABSTRACT
Objective To discuss the effect of microRNA -27a on U251 glioma cells.Methods Over-expression or inhibition of miR -27a in U251 glioma cells were done by transient transfection of miR -27a mim-ics or AMO-27a in vitro.Cell viability was detected by MTT assay .Invasion ability of U251 was detected by tr-answell invasion assay.The level of miR-27a and PPARγwere detected by real -time PCR.Results Under in-hibition of miR-27a condition,the proliferation and invasiveness of U 251 glioma cells were decreased .The level of PPARγwas significantly increased ,whereas the level of miR-27 a was decreased .Overexpression of miR-27 a increased the proliferation and invasiveness of U 251 glioma cells and decreased the level of PPARγ.Conclusion Inhibition of miR-27a is benefit for inhibiting the proliferation and invasiveness of U 251 glioma cells.
