Yan et al. (11) found that compared with the model group, fasting blood glucose (FBG), serum fasting insulin (FINS), insulin sensitivity index (HOMA-IS) and insulin resistance index (HOMA-IR) of rats in the extract-treated groups were significantly decreased, while high density lipoprotein (HDL) was significantly increased (p < 0.05). This evidence concerns the gene INS and Insulin resistance.
