Abstract
This study was designed to investigate the pro-inflammatory cytokines and their involvement in the cytotoxic potential of fluoride (F) in HeLa cells. HeLa cells were cultured with varying F concentrations (1–50 mg/L) for 48 h, and treatment effects were analyzed. The viability of HeLa cells was determined with a colorimetric method. The concentrations of IL-1β, IL-2, IL-6, and TNF-a in culture supernatant were measured through enzyme linked immunosorbent assay (ELISA). The mRNA expression levels of IL-1β, IL-2, IL-6 and TNF-a were subjected to transcript analysis and quantified through reverse transcription real-time PCR. Results showed that 10, 20 and 50 mg/L F significantly decreased the viability of HeLa cells incubated for 24 and 48 h. With their cytotoxic effect, the concentrations of IL-1β, IL-2, IL-6, and TNF-a decreased significantly in response to F, especially at 20 and 50 mg/L for 48 h. The mRNA expression levels of IL-1β, IL-2, IL-6, and TNF-a were downregulated at 50 mg/L F for 48 h. Therefore, F inhibited HeLa cell growth; as such, F could be used to alleviate the inhibition of pro-inflammatory cytokine expression.
