Abstract:
Objective:To investigate the effect of perfluorooctane sulfonate (PFOS) on inflammatory factors in human placental trophoblast (HTR-8/Svneo) cells.Methods:HTR-8/Svneo cells were exposed to different concentrations of PFOS (0, 0.01, 0.1, 1.0 mg/L) for 24 h, and the cell survival rates were measured by CCK8. Secretion levels of interleukin-6 (IL-6) , tumor necrosis factor-alpha (TNF-α) and interleukin-10 (IL-10) were detected by ELISA. The mRNA expressions of IL-6, TNF-α and IL-10 were detected by fluorescence quantitative PCR. One-way ANOVA was used to analyse the expressions of inflammatory factors.Results:Compared with the control group, the survival rates of 0.1 and 1.0 mg/L PFOS groups were significantly decreased ( P<0.05) . Compared with the control group, the secretion levels of IL-6 were decreased in the 0.01, 0.1 and 1.0 mg/L PFOS groups ( P<0.05) , the concentrations of TNF-α were increased in the 0.01 and 1.0 mg/L PFOS groups ( P<0.05) , and the concentrations of IL-10 were increased in the 0.1 and 1.0 mg/L PFOS groups ( P<0.05) . Compared with the control group, the expressions of IL-6 mRNA were increased in the 0.1 and 1.0 mg/L PFOS groups ( P<0.05) , and the expressions of IL-10 mRNA were decreased in the 0.01 mg/L, 0.1 mg/L and 1.0 mg/L PFOS groups ( P<0.05) . Conclusion:PFOS can induce changes in the secretion levels of inflammatory cytokines in HTR-8/Svneo cells, resulting in decreased activity of placental trophoblast cells and abnomal placental function.
