Objective To discuss the effects of hUHRF1 gene on proliferation and apoptosis effects of human ovarian cancer cell line SKOV-3. Methods Small interfering RNA (siRNA) for hUHRF1 gene sequence was transfected into SKOV-3 cells, Real-time quantitative polymerase chain reaction (RT- qPCR) and Western blotting assays were used to detect the mRNA and protein expression levels of hU- HRF1 respectively before and after siRNA transfection. Cell counting Kit-8 ( CCK-8 ) assay was used to in- vestigate proliferation. Flow cytometry was used to measure apoptosis. Results mRNA expression of hU- HRF1 was significantly decreased in SKOV-3 cells after the transfection of siRNA ( P 〈 O. O1 ). Relative expression of hUHRF1 protein in transfection group, negative control group and blank group was O. 72 ± 0.42, 1.66 ± O. 27 and 1.62 ± 0. 29 respectively. The proliferation of SKOV-3 cells was inhibited after transfection. Apoptosis rate of SKOV-3 cells in transfection group, negative control group and blank group was (42. 320 ± 4. 174 ) %, ( 17. 740 ± 1. 786 ) % and ( 15.440 ± 1. 233 ) %, respectively. Conclusion Using the siRNA gene silencing techniques, the expression of hUHRF1 is significantly inhibited after gene silencin.g in SKOV-3 cells, which can effectively inhibited SKOV-3 cell proliferation and induced apoptosis.
