A role for rev-erbα ligands in regulation of adipogenesis

Area of Science:

• Molecular Biology
• Endocrinology
• Chronobiology

Background:

• Rev-erbs are nuclear receptors (NRs) involved in circadian rhythm regulation.
• They are widely expressed, with high prevalence in liver, adipose tissue, skeletal muscle, and brain.
• Rev-erbs exhibit circadian expression patterns.

Purpose of the Study:

• To review the discovery of Rev-erbs as ligand-regulated receptors.
• To explore the role of natural and synthetic Rev-erb ligands in adipogenesis.
• To highlight the potential of pharmacological modulation of Rev-erbs for metabolic diseases.

Main Methods:

• Literature review of studies on Rev-erb function and ligand interactions.
• Analysis of research on heme and synthetic ligands (e.g., GSK4112/SR6452).
• Examination of data concerning Rev-erb activity in adipogenesis.

Main Results:

• Rev-erbs' repressive activity is modulated by the endogenous ligand heme.
• The first synthetic Rev-erb ligand, GSK4112/SR6452, has been reported.
• Both natural and synthetic ligands impact adipogenesis.

Conclusions:

• Rev-erbs are confirmed as ligand-regulated receptors.
• Pharmacological targeting of Rev-erbs holds promise for metabolic disease therapies.
• Ligand-mediated modulation of Rev-erbs is a viable strategy for influencing adipogenesis.
