What was done
This narrative review synthesized literature on estrogen receptor signaling (ERα, ERβ, and GPR30), downstream metabolic pathways (including mTOR signaling, autophagy, and adipogenesis), and epigenetic mechanisms (DNA methylation and histone modifications) in subcutaneous and visceral adipocytes.
What was found
The abstract reports no numerical data or quantitative effect sizes. It describes that estrogen promotes gynoid rather than visceral fat distribution, hormone-replacement therapy reduces central adiposity in postmenopausal women, and mouse studies show estrogen protects against adipose inflammation and fibrosis prior to obesity onset. The review highlights that estrogen mediates epigenetic remodeling of adipogenic genes, though depot-specific mapping across adipocyte subtypes remains incomplete.
Why it matters
It outlines the transcriptional and epigenetic pathways through which estrogen governs adipose tissue function, providing mechanistic context for sex differences in fat distribution and metabolic disease risk.
Limits
As a narrative review, it lacks systematic search methodology, quality assessment, and pooled quantitative data. Much of the cited mechanistic evidence derives from mouse models and in vitro adipocyte systems, and epigenetic effects across specific human adipose depots are not yet fully mapped.
