Effects of RSF-1 on proliferation and apoptosis of breast cancer cells.

Effects of RSF-1 on proliferation and apoptosis of breast cancer cells. Oncol Lett. 2018 Oct;16(4):4279-4284 Authors: Liu Y, Gai J, Fu L, Zhang X, Wang E, Li Q Abstract Effect of interference with chromatin remodeling and spacing factor-1 (RSF-1) on proliferation and apoptosis of breast cancer cells was investigated. MCF-7 and SKBR-3 cells were cultured in vitro and were divided into 3 groups: control group, negative siRNA control group (NC) and RSF-1 siRNA group. Western blot analysis was used to detect the expression of RSF protein after interference. Cell Counting Kit-8 (CCK-8) method was used to detect the effect of RSF-1 siRNA on cell proliferation. Plate cloning assay was used to detect the effect of RSF-1 siRNA on cell clone formation ability. Annexin V/PI double staining method was used to detect the effect of RSF-1 siRNA on cell apoptosis. Effect of RSF-1 siRNA on nuclear factor-κB (NF-κB) and its downstream signaling pathway were detected by western blot analysis. Western blot analysis showed that RSF-1 siRNA significantly downregulated the expression of RSF-1 protein in MCF-7 and SKBR-3 cells at 72 h after transfection (P<0.01). Cell proliferation assay showed that RSF-1 siRNA significantly reduced the proliferation ability and clone formation ability of MCF-7 and SKBR-3 cells compared with the control group (P<0.01). Annexin V/PI double staining assay results showed that compared with the control group, RSF-1 siRN...
