Physiological functions of the mitochondrial uncoupling proteins UCP2 and UCP3

Abstract

Evidence for the physiological functions of UCP2 and UCP3 is critically reviewed. They do not mediate adaptive thermogenesis, but they may be significantly thermogenic under specific pharmacological conditions. There is strong evidence that the mild regulated uncoupling they cause attenuates mitochondrial ROS production, protects against cellular damage, and diminishes insulin secretion. Evidence that they export fatty acids physiologically is weak. UCP2 and UCP3 are important potential targets for treatment of aging, degenerative diseases, diabetes, and perhaps obesity.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • UCP2 and 3 actions are upregulated in response to oxidant stress caused by nutrient deprivation, glucose sensing, fatty acid metabolism, or other metabolic changes in order to lessen mitochondrial ROS production.

    “UCP1 plays a role in adaptive thermogenesis in mammalian brown adipose tissue to produce heat (314), whereas the actions of UCP2 and 3 are upregulated in response to oxidant stress caused by nutrient deprivation, glucose sensing, fatty acid metabolism, or other metabolic changes in order to lessen mitochondrial ROS production (49).”

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.
