Genistein and 17β-Estradiol Protect Hepatocytes from Fatty Degeneration by Mechanisms Involving Mitochondria, Inflammasome and Kinases Activation

Oxidative stress and mitochondria dysfunction could be involved in the onset of non-alcoholic fatty liver disease (NAFLD) and in its progression to non-alcoholic steatohepatitis (NASH). Estrogens/phytoestrogens could counteract liver fat deposition with beneficial effects against NAFLD by unclear mechanisms. We aimed to analyze the protective effects elicited by genistein/estradiol in hepatocytes cultured in NAFLD-like medium on cell viability, triglycerides accumulation, mitochondrial function and oxidative stress and the role of NLRP3 inflammasome, toll like receptors 4 (TLR4), Akt and 5' AMP-activated protein kinase (AMPK)α1/2.
