ERRα: a metabolic function for the oldest orphan

Open access
Villena, Josep A., Kralli, Anastasia·2008·Trends in Endocrinology & Metabolism

Abstract

Estrogen receptor related receptor (ERR)alpha was one of the first identified (1988) orphan nuclear receptors. Many of the orphan receptors identified after ERRalpha were deorphanized in a timely manner and appreciated as key transcriptional regulators of metabolic pathways. ERRalpha, however, remains an orphan. Nevertheless, recent studies have defined regulatory mechanisms and transcriptional targets of ERRalpha, allowing this receptor to join ranks with other nuclear receptors that control metabolism. Notably, mice lacking ERRalpha show defects when challenged with stressors that require a 'shift of gears' in energy metabolism, such as exposure to cold, cardiac overload or infection. These findings establish the importance of ERRalpha for adaptive energy metabolism, and suggest that strategies targeting ERRalpha may be useful in fighting metabolic diseases.

  • HIF-1α is a key factor in suppressing mitochondrial biogenesis and PGC-1α expression through negative regulation of MYC and MYC-dependent transcription factors (PPARs and ERRs) that activate the PGC-1α gene.

    “HIF-1α is also a key factor in suppressing mitochondrial biogenesis and PGC-1α expression through mechanisms of negative regulation of the transcription factor MYC and the MYC-dependent transcription factors (PPARs and ERRs) that activate the PGC-1α gene [14,86,87].”

    From Protective Effects of PGC-1α Activators on Ischemic Stroke in a Rat Model of Photochemically Induced Thrombosis (2021) · cites this paper as [14]

    The sections on regulation and cellular function of ERRα (page not specified) link PGC-1α and ERRα to mitochondrial biogenesis. They do not establish the attributed mechanism: HIF-1α suppressing MYC, MYC-dependent PPARs or ERRs activating the PGC-1α gene, or the resulting suppression of PGC-1α expression. The paper instead describes PGC-1α as regulating ERRα expression and ERRα as a downstream effector of PGC-1α. (LLM, conf=0.78)

  • Improvement of microcirculation and penumbral tissue oxygenation mediated by Mexidol and Semax may be crucial to reverse the HIF-1α-dependent blockade of PGC-1α expression.

    “Improvement of microcirculation and penumbral tissue oxygenation mediated by the drugs Mexidol and Semax may be crucial to reverse the HIF-1α-dependent blockade of PGC-1α expression [14,86,87].”

    From Protective Effects of PGC-1α Activators on Ischemic Stroke in a Rat Model of Photochemically Induced Thrombosis (2021) · cites this paper as [14]

    The section ‘Regulation of ERRα: the roles of PGC-1α and PGC-1β’ discusses PGC-1α in energy metabolism, but does not address HIF-1α-dependent suppression of its expression. Searches for HIF-1α, hypoxia, oxygenation, Mexidol, Semax, and penumbral microcirculation found no passage supporting the proposed mechanism; page numbers were unavailable in our copy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
