Abstract:

Non-alcoholic fatty liver disease (NAFLD) is now a public health issue worldwide, but no drug has yet received approval. Genistein, an isoflavonoid derived from soybean, ameliorates high-fat-diet-induced NAFLD in mice, but the molecular underpinnings remain largely elusive. Arachidonic acid (AA) is a major ingredient of animal fats, and the AA cascade has been implicated in chronic inflammation. In this study, we investigated whether genistein was against NAFLD by targeting the AA cascade. Using a mouse model, we showed that genistein supplementation improved high-fat-diet-induced NAFLD by normalizing hepatomegaly, liver steatosis, aminotransferase abnormalities, and glucose tolerance. The thromboxane A(TXA) pathway was aberrantly active in NAFLD, evidenced by an elevation of circulating TXAand hepatic thromboxane Areceptor expression. Mechanistically, we found that genistein directly targeted cyclooxygenase-1 activity as well as its downstream TXAbiosynthesis, while the TXApathway might mediate NAFLD progression by impairing insulin sensitivity. Taken together, our study revealed a crucial pathophysiological role of the TXApathway in NAFLD and provided an explanation as to how genistein was against NAFLD progression.
