				        	Objective To investigate the effect of LY294002 on proliferation of cultured human glomerular mesan-gial cells, and to study on the mechanism underlying this proliferation. Methods Different concentrations of LY294002 (0.02,0.2,2,20,100 mg/L) were administrated to the cultured human glomerular mesangial cells. The effects of mesangial cell proliferation were measured using CCK-8 colorimetric assay. Under appropriate concentrations, proliferation of cultured mesangial cells were measured using CCK-8 at 0.5, 1, 24, 48 hours of drug administration time. Results LY294002(0.02 mg/L)didn’t obviously inhibited the growth of mesangial cells(P>0.05), the inhibition rate was 5.05%. The effect of LY294002 on the cells decreased with rising concentration (0.2 to 20 mg/L) in a dose-dependent manner (P<0.05). Mesan-gial cells would stop growing with the increasing concentration. LY294002 didn’t obviously inhibited the growth of mesan-gial cells at 2 mg/L during 0 to 1 h(P>0.05), but inhibited proliferation gradually from 1 to 48 h (P<0.05). Conclu-sion Within the certain range of concentration and time, the LY294002 inhibits the proliferation of human glomerular me-sangial cells, and PI3K/Akt/mTOR signaling pathway may regulate the proliferation of human mesangial cell.
