Abstract
AIM: To observe the effect of Chunyangzhengqi capsules on the growth of gastric cancer MGC-803 cells.
METHODS: MGC-803 cells were treated with Chunyangzhengqi capsules at a concentration of 200, 400, 800 or 1600 μg/mL. Cell morphological changes were observed under an inverted microscope. Cell cycle was examined by flow cytometry (FCM). Apoptosis was analyzed by Hoechest-33258 staining. The spectrometry was used to detect Caspase3 activity.
RESULTS: Chunyangzhengqi capsules inhibited the proliferation of MGC-803 cells in a dose- and time-dependent manner. The IC50 values of Chunyangzhengqi capsules at 24, 48 and 72 h were 1734, 1534 and 1094 μg/mL, respectively. After treatment, cells exhibited apoptosis in morphology. Chunyangzhengqi capsules could induce apoptosis of MGC-803 cells and block cells at S phase. The activity of Caspase3 was significantly increased in cells treated with Chunyangzhengqi capsules at a concentration of 1600 μg/mL for 16 h.
CONCLUSION: Chunyangzhengqi capsules inhibit cell proliferation and induce apoptosis in human gastric cancer cell line MGC-803.
