Molecular pathways: the metabolic regulator estrogen-related receptor α as a therapeutic target in cancer.

Published

Journal Article

The estrogen-related receptor α (ERRα) is an orphan member of the nuclear receptor superfamily of transcription factors whose activity is regulated by the expression level and/or activity of its obligate coregulators, peroxisome proliferator-activated receptor γ coactivator-1 α and β (PGC-1α or PGC-1β). Under normal physiologic conditions, and in responding to different environmental stimuli, the ERRα/PGC-1 complex is involved in regulating metabolic homeostasis under conditions of high energy demand in brown adipocytes, proliferating T cells, and muscle. Interestingly, increased expression and activity of the ERRα/PGC-1 axis has also been shown to correlate with unfavorable clinical outcomes in both breast and ovarian tumors. The observation that ERRα activity is manifest in all breast tumor subtypes with particularly high activity being evident in ERα-negative, HER2-positive, and triple-negative breast cancers has raised significant interest in targeting this receptor for the treatment of those breast cancers for which therapeutic options are limited.
