ABSTRACT
Aim To establish insulin resistant HepG2 cell model induced by high concentration insulin in vitro culture and evaluate the effects of pioglitazone on insulin sensitivity and glucose metabolism in the cell model.Methods HepG2 cells were incubated with 5?10~(-7)mol?L~(-1) insulin for 16 h and insulin-stimulated()~3H-D glucose incorporation was determined.Then,insulin-stimulated glucose incorporation rate which was used to estimate insulin sensitivity of HepG2 cell,and glucose consumption,the amountsof glucose disappeared from the culture medium of HepG2 cells within 24 hours was determined.The insulin resistance cells were incubated with pioglitazone 1?10~(-5) mol?L~(-1).Results It was demonstrated that the incorporation rate of()~3H-D-glucose in insulin-resistant HepG2 cells was decreased significantly than that in the control cells.Insulin-resistant HepG2 cells were free from stimulation for 48 h by insulin,but the incorporation rate of()~3H-D-glucose was lower than that in control cells.Incubation of insulin resistance cells with pioglitazone significantly increased glucose uptake and glucose consumption by the cells compared with that of the control cells(P
