INS and Insulin resistance: TZDs could stimulate glucose transporter expressionand other proteins in the insulin pathway (cf [21]).Moreover, a decrease in the insulin resistance by TZDs could beexplained by a redistribution of the triglycerides circulating orcontent in liver and skeletal muscle into the adipose tissue.These modifications are associated with a decrease in plasma freefatty acid and triglyceride concentrations [22, 68].
