Abstract:

OBJECTIVE: To explore the effects of curcumin on apoptosis-related gene expression in HaCaT cells. METHODS:Immunocytochemistry and Western blot were used to detect the effects of curcumin on apoptosis-related protein expression. RESULTS:Immunocytochemistry staining results showed that the expression levels of  P53,Bax,Fas were upregulated significatntly while the products of Bcl-2 proteins were downregulated significantly in cells treated with 7.5 μg/mL curcumin. Western blot analysis confirmed the same results. CONCLUSION:Curcumin induced apoptosis of HaCaT cells by inhibiting expression of  Bcl- 2 gene and promoting the apoptosis genes p53,Bax and Fas activation.  Curcumin could induce apoptosis by regulation of a variety of apoptosis-related genes to activate the apoptosis signaling pathway.
