Abstract
AIM: To investigate the effect of curcumin on proliferation and apoptosis of cholangiocarcinoma cells and whether curcumin shows a therapeutic effect on cholangicarcinoma in vivo.
METHODS: CCK-8 assay was employed to investigate the effect of curcumin on cell proliferation in cholangiocarcinoma cell lines QBC939, RBE and TFK-1. Flow cytometry was employed to assess the effect of curcumin on cell apoptosis in cholangiocarcinoma cell lines. A nude mouse model of orthotopic transplantation of cholangiocarcinoma was developed to investigate the effect of curcumin on weight gain and survival state of mice.
RESULTS: Curcumin inhibited the proliferation of QBC939, RBE and TFK-1 cells (P < 0.05) in a dose- and time-dependent manner. Curcumin significantly induced apoptosis of cholangiocinoma cells. When curcumin concentrations were 0, 0.1, 1, 5 and 10 μmol/L, the corresponding apoptosis rates were 8.41% ± 1.22%, 21.49% ± 2.58%, 48.53% ± 2.41%, 69.75% ± 1.46% and 87.59% ± 3.25%, respectively (P < 0.05). In vivo experimental results show that curcumin significantly prolonged the survival time of tumor-bearing mice (P < 0.05) and significantly improved their survival state (P < 0.05).
CONCLUSION: Curcumin inhibits cell proliferation and induces apoptosis in cholangiocarcinoma cell lines in vitro, and prolongs the survival time of cholangiocarcinoma bearing mice and improve their survival status in vivo.
