Estrogen increases perilipin protein levels in adipocytes, which suppresses basal lipolysis but significantly enhances catecholamine-stimulated lipolysis.
Estrogen helps your fat cells release stored fat more efficiently when stimulated by stress or exercise (catecholamines) by increasing a protective protein called perilipin. This makes your fat cells more responsive to signals that tell them to burn fat.
GoodSupportsHIGH confidence
Adipocytes of OVX-E2 mice contained >3-fold more perilipin protein than adipocytes of pairfed control (OVX) mice, and this difference was associated with enhanced ex vivo lipolytic response to catecholamines
Why this rating
Clear experimental data showing protein levels and functional lipolysis rates.

More from this paper
- Estrogen (E2) reduces adiposity and adipocyte size independently of energy intake by down-regulating lipogenic genes (SREBP-1c, FAS, ACC-1) and up-regulating lipid oxidation pathways (PPAR-alpha, AMPK) in skeletal muscle and adipose tissue.Good
- Estrogen rapidly activates AMP-activated protein kinase (AMPK) in skeletal muscle via non-genomic mechanisms, promoting fat oxidation and down-regulating lipogenesis.Good
