Abstract (original English)
Premenopausal women preferentially store fat in subcutaneous depots, which provides protection against cardiometabolic disease. Their white adipose tissue also exhibits a more thermogenic, brown-like profile compared with that of men, yet the mechanisms underlying this sex-specific benefit remain unclear. Here, we show that Nuclear Receptor Coactivator 1 is highly expressed in human subcutaneous fat, with further induction during the conversion of white to beige adipocytes and in response to caloric restriction. Loss of Nuclear Receptor Coactivator 1 in subcutaneous adipocytes revealed a cell-autonomous role in promoting beiging by directly regulating the thermogenic factor Uncoupling Protein 1 and sex-dependent mitochondrial gene networks activated by cold and adrenergic stimulation. Acting together with GATA binding protein 3, it establishes elevated basal thermogenic tone in female subcutaneous fat. Female mice lacking this coregulator progressively developed obesity and glucose intolerance, and a male-like fat distribution, with increased visceral fat and reduced beige adipocytes. These findings identify Nuclear Receptor Coactivator 1 as a sex-specific determinant of adipose tissue remodelling and female metabolic resilience.
