Effects of altered hepatic lipid metabolism on regulation of hepatic iNOS

An altered hepatic lipid metabolism involves multifactorial pathologies such as hepatic inflammation, insulin resistance and oxidative stress. Immunity has an essential role in the regulation of glucose and lipid metabolism in the liver. Inducible nitric oxide (NO) synthase (iNOS) has been proposed as an important factor that interplays between immunity and energy metabolism and also in the pathogenesis of obesity-linked insulin resistance. In the liver, locally produced NO plays a protective role during inflammation, and the balance of NO protective and cytotoxic effects is very important. This review is focused on understanding the molecular mechanisms of iNOS regulation in the state of altered hepatic lipid metabolism, which is critical for developing new strategies for treatment of hepatic disorders
