Abstract:
Objective:To investigate the effect of kaempferol on proliferation, migration, and invasion of cervical cancer SiHa cells by regulating circFBXW7.Methods:SiHa cells were treated with kaempferol at low, medium, and high doses (15, 30, and 60 μmol/L) for 24 h. Untreated SiHa cells were used as the control group. CCK-8 was used to detect the effect of kaempferol on the proliferation of SiHa cells. Transwell was used to detect the effect of kaempferol on the migration and invasion of SiHa cells. Real-time fluorescence quantitative polymerase chain reaction was used to detect the expression of circFBXW7 in SiHa cells. pcDNA and pcDNA-circFBXW7 were transfected into SiHa cells, respectively, and si-NC and si-circFBXW7 were transfected into SiHa cells after adding 60 μmol/L kaempferol treatment for 24 h. The effects of circFBXW7 and its knockdown, circFBXW7, on the proliferation, migration, and invasion of SiHa cells were investigated, and the effects of E-cadherin and N-cadherin protein expression levels were detected by Western Blot. Results:Compared with the control group, the cell value-added, migration, and invasion abilities of the low, medium, and high dose groups were decreased (all P < 0.05) and were dose-related, and the expression of circFBXW7 was increased ( P < 0.05). After transfection with pcDNA-circFBXW7, the expression of circFBXW7 increased ( P < 0.05), while promoting the proliferation, cell migration, and invasion of kaempferol on SiHa cells (all P < 0.05). After transfection with si-circFBXW7, the expression of circFBXW7 decreased ( P < 0.05), while inhibiting the proliferation, cell migration, and invasion of kaempferol on SiHa cells (all P < 0.05). That indicated that the transfection of si-circFBXW7 could attenuate the inhibitory effects of kaempferol on the above oncogenic phenotypes of SiHa cells. Compared with the control group, E-cadherin expression was upregulated, and N-cadherin expression was downregulated in the low, medium, and high dose groups (all P < 0.05) in a dose-related manner. After transfection of pcDNA-circFBXW7 with SiHa cells, the expression of E-cadherin was increased, and the expression of N-cadherin was decreased (all P < 0.05). After transfection of si-circFBXW7 with SiHa cells, the expression of E-cadherin decreased, and the expression of N-cadherin increased (all P < 0.05). Conclusions:Kaempferol can reduce the proliferation, migration, and invasion abilities of SiHa cells by promoting circFBXW7 expression.
