Abstract

Abstract: Adipocytes play an essential role in the maintenance of whole-body energy homeostasis. White adipocytes regulate energy storage, whereas brown and beige adipocytes regulate energy expenditure and heat production. De novo production of adipocytes ( i.e. adipogenesis) and their functions are dynamically controlled by environmental cues. Environmental changes ( e.g. temperature, nutrients, hormones, cytokines) are transmitted via intracellular signaling to facilitate short-term responses and long-term adaptation in adipocytes; however, the molecular mechanisms that link the environment and epigenome are poorly understood. Our recent studies have demonstrated that environmental cues dynamically regulate interactions between transcription factors and epigenomic chromatin regulators, which together trigger combinatorial changes in chromatin structure to influence gene expression in adipocytes. Thus, environmental sensing by the concerted action of multiple chromatin-associated protein complexes is a key determinant of the epigenetic regulation of adipocyte functions. Graphical Abstract:
