Abstract

Background:Digestive system is the most common type of cancer in Iran with 38 percent of the cases.The risk of this cancer is influenced by both environmental and genetic factors. Curcumin is kind of phytochemicals which is important in chemoprevention strategy, in order to slow, block, or reverse the process of carcinogenesis.Researchhave shown that the possible role of curcumin to prevent or delay the diagnosis of colorectal cancer. In this research the effect of curcumin on proliferation of HT_29 cancerous cells were assayed. Materials and Methods:In this experimental research HT_29 cell line were cultured in DMEM medium containing 10% FBS (Fetal Bovine Serum, Gibco, Invitrogen) and 100 U/ml penicillin and 100mg/ml streptomycin. Different concentrations of curcumin on the growth of HT_29 cells were determined by MTT assay and the type of death induced was assessed by DAPI staining method.All experiments were done three times and data were analyzed byone –way ANOVA test and Instate 3 software. Results:The cell growth-inhibiting rate was about 53% at 50μM curcumin concentration after 24h of treatment(IC50). Vacuolation and significant decrease of cells were observed after 72h of treatment. Moreover, induction of apoptosis was observed with the DAPI staining method. Conclusion:According to molecular mechanisms of cell proliferation and curcumin ability in the induction of pro_apoptotic proteins and the inhibition of anti_apoptotic proteins as well as inhibition of as survival pathways,like NF_KB and AKT, this predisposition makes curcumin a good anticancer drug. Keywords:Curcumin,Colon cancer,HT_29 cancer cell line, Proliferation.
