Abstract

Native LDL, in low concentrations, promotes proliferation of cultured human glomerular mesangial cells. LDL stimulated [(3)H]-thymidine incorporation into DNA of human glomerular mesangial cells. Increased concentrations of LDL led to increased [(3)H]-thymidine incorporation. When LDL concentrations were 5, 10 and 50 microg ml(-1), [(3)H]-thymidine incorporation was 919.5+/-216, 1106+/-132, and 1200+/-210, respectively. When Cordyceps sinensis 100, 200, 300, 400 microg ml(-1) plus LDL 10 microg ml(-1) were added, [(3)H]-thymidine incorporation was 99+/-19 and 53+/-8, respectively, P<0.01 compared with controls. With Cordyceps militaris at similar concentrations plus LDL 10 microg ml(-1), [(3)H]-thymidine incorporation was respectively 192+/-75, 168+/-66, 145+/-53 and 72+/-16, P<0.01 compared with controls. The data suggest that LDL may play a critical role in mediating mesangial cell hypertrophy or proliferation involved in the development of glomerulosclerosis. Cordyceps sinensis and Cordyceps militaris inhibited, to a certain degree, proliferation of cultured human glomerular mesangial cell induced by LDL.
