摘要

Lifestyle and genetic factors contribute to the initiation of oxidative stress and inflammation in diabetes mellitus (DM). Oxidative stress and lipid peroxidation worked in an orchestrated manner and reported to be strongly associated with the formation of the hyperlipidemic condition in DM patients. Isoquercetin, a bioactive constituent isolated from guava leaves has attracted considerable attention because of its antidiabetic activity. The antidiabetic activity of guava leaves may be due to the presence of isoquercetin at a significant level. However, how isoquercetin regulates different pathways in DM is insufficiently studied. We have selected versatile regulators of oxidative stress and inflammatory pathways to fully analyze if isoquercetin effectively modulated the genes of these pathways. At the end of our experimental duration, rats were dissected and analyzed for the oxidative stress, lipid peroxidation, inflammatory and lipid markers. The nuclear factor erythroid 2–related factor 2 (Nrf2) pathway is believed to be the key regulator of expression of various antioxidant enzyme genes and it is directly or indirectly related to nuclear factor Kappa- B (NF-kB) and AMP-activated protein kinase (AMPK) pathways. Therefore, we tend to study the effects of STZ on Nrf2, NF-kB and AMPK pathway and how the isoquercetin treatment performs at a molecular level to overcome the burden of DM. The results of our study provided convincing evidence of significant pharmacological properties of isoquercetin in context of its ability to inhibit the oxidative stress elicited by the STZ through generation of the free radicals and regulation of the expression of Nrf2 pathway-associated proteins and genes and it also reduced the burden of hyperlipidemia and inflammation. By taking the above results into consideration isoquercetin can be studied further to elucidate its antidiabetic effects at various levels.
