Abstract:
Objective This study was to observe the biological effects of eprenone on proliferation ,migration and apoptosis in human gastric epithelial cell line .Methods Human gastric epithelial cells GES‐1 were cultured in vitro .MTT assay were used to e‐valuate the proliferation of GES‐1 cells in different concentrations of teprenone and ensure the appropriate drug concentration .T ran‐swell test and scratch test were used to detect the migration ability of GES‐1 cells treated with appropriate concentration of eprenone .Flow cytometry analysis were used to detect the apoptosis of GES‐1 cells treated by the appropriate concentration of eprenone .Results Treated with eprenone for 24 h ,the proliferation of GES‐1 cells were increased as the concentration of teprenone from 10 to 80 μmol/L ,but from 80 to 320 μmol/L ,the promoting effect showed no staticall significant changes .So the appropriate drug concentration was determined to be 80 μmol/L .Treated with teprenone (80 μmol/L) for 24 h ,the transwell test showed that the migration rate of the teprenone group was 3 .338 ± 0 .293 and the control group was 1 .328 ± 0 .208 .So the number of staining blue cells in eprenone group were more than in control group obviously under membrane of transwell chambers (P<0 .01) .Scratch test showed that the migration rate of the eprenone group was 1 .00 ± 0 .18 and the control group was 0 .72 ± 0 .08 .Similarly ,the migration rate of eprenone group was higher than the control group(P<0 .05) .Treated with teprenone (80 μmol/L) for 48 h ,the apoptosis rate of the teprenone group was (11 .90 ± 1 .53)% and the control group was (25 .61 ± 0 .15)% ,the cellular apoptosis of eprenone group was lower than the control group (P<0 .01) .Conclusion Teprenone can promote the proliferation and migration , inhibit the apoptosis of GES‐1 cells .
