Abstract:
Aim To study the effect of cobra venom nerve growth factor ( NGF) on inducing the apoptosis of LX2 cells, the key cells of hepatic fibrosis , through Akt signaling pathway and its underlying mechanism .Methods CCK-8 method was used to detect the pro-liferation of LX2 cells at different concentrations of NGF and LY294002 .Flow cytometry was applied to detect the effect of NGF on the apoptosis of LX 2 cells. Western blot was used to study the effects of NGF and LY294002 respectively , and their combination on the p-Akt protein level .Results NGF could decrease the survival rate of LX2 cells, and the minimum effective concentration was 1mg· L-1; it increased the apopto-sis rate of LX2 cells within the rise of concentration un-der a certain of range and decreased the expression level of p-Akt, but it had no significant effect on the ex-pression of Akt .Conclusions NGF may promote the apoptosis of LX2 cells by inhibiting the activation of PI3K/Akt signaling pathway in a concentration-de-pendent manner .The study of the pathogenesis of liver fibrosis is significant for the clinical treatment of liver fibrosis.
