Core Tip

Core Tip: It is widely accepted that adipocyte hypertrophy arises from an increase in lipogenesis and/or a reduction in lipolysis. Our findings reveal that despite the presence of adipocyte hypertrophy and visceral adiposity, the expression of genes related to both fatty acid biosynthesis and oxidation in visceral adipose tissue was significantly reduced following ovariectomy (OVX) in mice fed a high-fat diet, suggesting a comprehensive decline in metabolic activity. Remarkably, estrogen treatment fully reversed the disrupted expression patterns of lipid metabolic genes in OVX mice, correcting their disordered metabolic phenotype. This study unveils a novel mechanism underlying visceral adiposity and highlights estrogen's protective role against visceral obesity.
