The Impact of Skeletal Muscle ERα on Mitochondrial Function and Metabolic Health.

Summary of "The Impact of Skeletal Muscle ERα on Mitochondrial Function and Metabolic Health."

The incidence of chronic disease is elevated in women after menopause. Increased expression of ESR1 (the gene that encodes the estrogen receptor alpha, ERα) in muscle is highly associated with metabolic health and insulin sensitivity. Moreover, reduced muscle expression levels of ESR1 are observed in women, men, and animals presenting clinical features of the metabolic syndrome (MetSyn). Considering that metabolic dysfunction elevates chronic disease risk, including type 2 diabetes, heart disease, and certain cancers, treatment strategies to combat metabolic dysfunction and associated pathologies are desperately needed. This review will provide published work supporting a critical and protective role for skeletal muscle ERα in the regulation of mitochondrial function, metabolic homeostasis, and insulin action. We will provide evidence that muscle-selective targeting of ERα may be effective for the preservation of mitochondrial and metabolic health. Collectively published findings support a compelling role for ERα in the control of muscle metabolism via its regulation of mitochondrial function and quality control. Studies identifying ERα-regulated pathways essential for disease prevention will lay the important foundation for the design of novel therapeutics to improve metabolic health of women while limiting secondary complications that have historically plagued traditional hormone replacement interventions.

Medical and Biotech [MESH] Definitions

A subtype of mitochondrial ADP, ATP translocase found primarily in heart muscle (MYOCARDIUM) and skeletal muscle (MUSCLE, SKELETAL).

A mitochondrial uncoupling protein that is expressed in many tissues and exhibits the greatest expression in SKELETAL MUSCLE. It regulates mitochondrial ATP production and the generation of REACTIVE OXYGEN SPECIES.

Large, multinucleate single cells, either cylindrical or prismatic in shape, that form the basic unit of SKELETAL MUSCLE. They consist of MYOFIBRILS enclosed within and attached to the SARCOLEMMA. They are derived from the fusion of skeletal myoblasts (MYOBLASTS, SKELETAL) into a syncytium, followed by differentiation.

Skeletal muscle structures that function as the mechanoreceptors responsible for the stretch or myotactic reflex (REFLEX, STRETCH). They are composed of a bundle of encapsulated SKELETAL MUSCLE FIBERS, i.e., the intrafusal fibers (nuclear bag1 fibers, nuclear bag2 fibers, and nuclear chain fibers) innervated by sensory neurons.

A perilipin that functions in LIPOGENESIS; LIPOLYSIS; and fatty acid oxidation in BROWN ADIPOSE TISSUE; heart, liver, and skeletal muscle. It recruits MITOCHONDRIA to the surface of LIPID DROPLETS where it functions in both the storage of fatty acids as TRIGLYCERIDES, and their release for mitochondrial fatty acid oxidation in response to metabolic needs.
