Abstract: Objective The aim of this study was to investigate the expression of microRNA-150(miR-150)in human epithelial ovarian cancer cells and its effect on proliferation,apoptosis,invasion and metastasis of human epithelial ovarian cancer cells.Methods The expression level of miR-150 in cells from each treatment group was detected by Real-Time PCR(qRT-PCR);effects of proliferation,apoptosis,invasion and metastasis of epithelial ovarian cancer cells was investigated by MTT,flow cytometry,and transwell assays.Results Compared with normal ovarian epithelial cells(T29),the expression of miR-150 was significantly decreased in epithelial ovarian cancer cells(A2780 and OVCAR3)(P<0.01); After transfection miR-150 mimic,the expression of miR-150 in A2780 and OVCAR3 cells was significantly increased(P<0.01);After 3 d of transfection,the OD values of the miR-150 mimic group(A2780:1.12±0.03;OVCAR3:1.91±0.03)were lower than that in the blank group(A2780:2.35±0.09;OVCAR3:2.63±0.07)and the miR-150 NC group(A2780:2.18±0.07;OVCAR3:2.43±0.11)(P<0.01);The apoptotic rate in the miR-150 mimic group(A2780:16.10±0.58%;OVCAR3:15.16±1.30%) were significantly increased when compared to the blank group(A2780:10.07±0.66%;OVCAR3:3.81±0.24%) and the miR-150 NC group(A2780:10.36±1.08%;OVCAR3:4.89±0.07%)(P<0.01);The number of transmembrane cells in the miR-150 mimic group(A2780:38.67±2.03;OVCAR3:28.67±2.03)was higher than that in the blank group(A2780:76.30±7.45;OVCAR3:55.67±3.18)and the miR-150 NC group(A2780:74.33±5.78;OVCAR3:56.33±3.84)(P<0.01).Conclusion The decreased expression of miR-150 in epithelial cancer cells may be one of the mechanisms of proliferation,invasion and metastasis of epithelial ovarian cancer.Up-regulation of miR-150 may inhibit the proliferation of epithelial ovarian cancer cells and promote apoptosis to reduce the abilities of invasion and metastasis in epithelial ovarian cancer cells.
