Advances in regulation of hypoxia on adipocyte development and lipid metabolism

Abstract

The growth, differentiation and proliferation of adipose cells run through the whole life process. Dysregulation of lipid metabolism in adipose cells affects adipose tissue immunity and systemic energy metabolism. Increasingly available data suggest that lipid metabolism is involved in regulating the occurrence and development of various diseases, such as hyperlipidemia, nonalcoholic fatty liver disease, diabetes and cancer, which pose a major threat to human and animal health. Hypoxia inducible factor (HIF) is a major transcription factor mediating oxygen receptors in tissues and organs. HIF can induce disease by regulating lipid synthesis, fatty acid metabolism and lipid droplet formation. However, due to the difference of hypoxia degree, time and mode of action, there is no conclusive conclusion whether it has harmful or beneficial effects on the development of adipocytes and lipid metabolism. This article summarizes the regulation of hypoxia stress mediated transcription regulators and regulation of adipocyte development and lipid metabolism, aiming to reveal the potential mechanism of hypoxia induced changes in adipocyte metabolism pathways.
