UCP1 and mitochondrial uncoupling

The mitochondrial uncoupling protein UCP1: a gated pore.

The uncoupling protein UCP1 is a member of a superfamily of homologous proteins formed by the mitochondrial metabolite transporters. Although they act in vivo as carriers, under specific experimental conditions some of these transporters have been shown to behave as channels. This dual transport operation suggests that these carriers are likely to be formed by two differentiated functional and ...

Circadian Variations of Serum Mitochondrial Uncoupling Protein 1 (UCP1) Levels and Rectal Temperature in Capra Hircus

Background: The daily rhythm of body temperature is an important process to be studied not only to advance knowledge on the temporal variability of thermal homeostasis but also has a means to facilitate the study of biological rhythmicity in general. The aim of the present study was to study the daily rhythm of rectal temperature and the changes in the serum levels of mitochondrial uncoupling p...

Mitochondrial uncoupling prevents cold-induced oxidative stress: a case study using UCP1 knockout mice.

The relationship between metabolism and reactive oxygen species (ROS) production by the mitochondria has often been (wrongly) viewed as straightforward, with increased metabolism leading to higher generation of pro-oxidants. Insights into mitochondrial functioning show that oxygen consumption is principally coupled with either energy conversion as ATP or as heat, depending on whether the ATP-sy...

Overexpression of mitochondrial uncoupling protein 1 (UCP1) induces a hypoxic response in Nicotiana tabacum leaves

Mitochondrial uncoupling protein 1 (UCP1) decreases reactive oxygen species production under stress conditions by uncoupling the electrochemical gradient from ATP synthesis. This study combined transcriptome profiling with experimentally induced hypoxia to mechanistically dissect the impact of Arabidopsis thaliana UCP1 (AtUCP1) overexpression in tobacco. Transcriptomic analysis of AtUCP1-overex...
