TLDR
An increase in the number of fast‐oxidative‐glycolytic (type IIA) fibers in the pectoralis muscle, which contains exclusively type IIB fibers in control chickens, was observed in cold‐acclimated chickens, providing novel information about possible regulatory pathways in avian skeletal muscle during thermogenesis.

Metabolic characteristics and oxidative damage to skeletal muscle in broiler chickens exposed to chronic heat stress.

TL;DR: It is suggested that chronic heat exposure decreases metabolic oxidation capacity in skeletal muscle of broiler chickens, possibly due to a decrease in metabolic oxidation Capacity or due to the self-propagating scavenging system, though the system was not fully activated.

Acute Heat Stress Induces Oxidative Stress and Decreases Adaptation in Young White Leghorn Cockerels by Downregulation of Avian Uncoupling Protein

TL;DR: Results suggest that exposure of young cockerels to heat stress stimulates mitochondrial superoxide production, possibly via downregulation of avUCP, and can be assumed that appropriate expression ofAvUCP may alleviate overproduction of mitochondrialsuperoxide and could help birds adapt to oxidative stress resulting from acute heat stress.

Sequential changes in superoxide production, anion carriers and substrate oxidation in skeletal muscle mitochondria of heat-stressed chickens.

TL;DR: The results suggest that overproduction of mitochondrial ROS in chicken skeletal muscle under the heat stress might result from enhanced substrate oxidation and downregulation of avUCP in a time‐dependent manner.

Endothermy in birds: underlying molecular mechanisms

TL;DR: The relationship between oxidative capacity and uncoupling indicates that there is a continuum of phenotypes that fall between the extremes of selection for increased heat production and increased aerobic activity, whereas increased cellular ATP demand is a prerequisite for increased oxidative capacity.
Journal ArticleDOI

Responses to temperature variation: integration of thermoregulation and metabolism in vertebrates.

TL;DR: Endothermic adaptive thermogenesis may result from the same regulatory pathways as ectothermic metabolic acclimation, and both could be considered as adaptive metabolic responses to temperature variation.

Molecular Cloning: A Laboratory Manual

TL;DR: Molecular Cloning has served as the foundation of technical expertise in labs worldwide for 30 years as mentioned in this paper and has been so popular, or so influential, that no other manual has been more widely used and influential.

Mechanisms Controlling Mitochondrial Biogenesis and Respiration through the Thermogenic Coactivator PGC-1

TL;DR: PGC-1, a cold-inducible coactivator of nuclear receptors, stimulates mitochondrial biogenesis and respiration in muscle cells through an induction of uncoupling protein 2 (UCP-2) and through regulation of the nuclear respiratory factors (NRFs).

A cold-inducible coactivator of nuclear receptors linked to adaptive thermogenesis.

TL;DR: Results indicate that PGC-1 plays a key role in linking nuclear receptors to the transcriptional program of adaptive thermogenesis.

Transcriptional co-activator PGC-1α drives the formation of slow-twitch muscle fibres

TL;DR: Using fibre-type-specific promoters, it is shown in cultured muscle cells that PGC-1α activates transcription in cooperation with Mef2 proteins and serves as a target for calcineurin signalling, which has been implicated in slow fibre gene expression.
