Insulin receptor is the target gene of miR-497, and elevated miR-497 might induce hepatic insulin resistance in HFD-MetS E3 Rats through inhibiting the expression of insulin receptor and confining the activation of IRS-1/PI3K/Akt/GSK-3β/GS pathway to insulin.
To evaluate whether hyperglycaemia in two lean patients with primary severe insulin resistance due to insulin receptor (IR) mutations and diabetes mellitus could be reduced by supplement of rosiglitazone for 180 days and secondary, to evaluate the effects on plasma NEFA, TG, Apo B, PAI-1 and serum insulin.
