Abstract: To observe the effect of curcumin(CCM)on the growth of gastric cancer cell BGC23. Methods:Humangastric cancer cell BGC23 was cultured with various concentrations of CCM(0,306090 and 120 p,mol/L)for 24 hours and 48hours. The proliferation of BGC23 cell was measured by MTT colorimetric assayand the cell cycle distribution was examined by11owcytometry. Cell apoptosis was determined by TUNEL. Results:The cell's pseudopodia was retracted after CCM treatment the cellsbecame small and round tumor giant cells were reduced or no tumor giant cells. MTT assay showed that CCM was significantly inhibitedthe growth of gastric cancer cells. FCM results suggested CCM alfected gastric. ancer cell cyclethe cells were arrested in G=/M phaseTUNEL results showed that CCM induced gastric cancer cell apoptosis(p0. OS-p0. O1)Conclusions:Curoumin inhibits the
