Abstract:
Objective To investigate the effect of curcumin on the expression of nuclear transcription factor (NF-kappa B) and its inhibitory protein (Iκ-Bα) in liver cancer cells (Hepg-2) induced by TNF-α, and explore its effect on non-alcoholic steatohepatitis. Methods The cells were divided into normal group, TNF-alpha group, and different concentrations of curcumin treatment group. MTT and Western blotting were used to assay curcumin’s effect on Hepg-2 proliferation activity and changes of NF-κB and Iκ-Bα’s in Hepg-2. Results Compared with the normal group, TNF-αgroup enhanced NF-κB and Iκ-Bαexpression, but the increase of Iκ-Bα had no statistical significance (P>0.05). Curcumin treatment group’s NF-κB expression was significantly weakened than TNF-α group, while Iκ-Bα was significantly enhanced than that of TNF-α group. Conclusion Curcumin can antagonize NF-κB inflammatory signaling pathway activation induced by TNF-α, thus reduce the inflammatory injury of the liver cells.
