Supporting Information - Supplemental Experimental Procedure : Muscle nonshivering thermogenesis in a feral mammal

, 2019
Muscle nonshivering thermogenesis (NST) was recently suggested to play an important role in thermoregulation of species lacking brown adipose tissue (BAT). The mechanism, which is independent of muscle contractions, produces heat based on the activity of

The impact of thermogenesis on the origin of insect pollination

Thermogenesis in plants is the ability to raise their temperature above that of the surrounding air through metabolic processes, and is especially detected in reproductive organs.

Accumulation of succinate controls activation of adipose tissue thermogenesis. [PDF]

, 2018
Thermogenesis by brown and beige adipose tissue, which requires activation by external stimuli, can counter metabolic disease1. Thermogenic respiration is initiated by adipocyte lipolysis through cyclic AMP-protein kinase A signalling; this pathway has ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Blubber Thickening Driven by UCP1 Inactivation: Insights from a Cetacean‐Like Transgenic Mouse Model

Integrative Zoology, EarlyView.
UCP1 inactivation of cetaceans in mice drives BAT whitening and iWAT hyperplasia, promoting fat accumulation for aquatic adaptation. Abstract Cetaceans possess thick blubber, a specialized adipose tissue essential for thermal insulation, a streamlined body form, energy storage, and buoyancy. However, the mechanisms that underpin this adaptation are not

Loss of histone methyltransferase Smyd3 triggers WAT browning and adaptive thermogenesis via enhancing PPARγ expression in a H4K20me3-dependent manner

Journal of Translational Medicine
Adaptive thermogenesis driven by brown/beige adipose tissue has gained attention as a promising strategy for combating obesity. Histone methyltransferase SET and MYND Domain Containing 3 (Smyd3) is strongly associated with metabolic and cardiovascular ...

Genomic Investigations Unveil the Genetic Underpinnings of Environmental Adaptation in African Goat Populations

Integrative Zoology, EarlyView.
This study integrates genomics and landscape genetics to analyze African goat environmental adaptation. Analyzing 1591 samples, it finds population structure differentiates geographically into four groups, with gene flow between wild Yura goats and North Africans.

Gut Microbiota of Gray Snub‐Nosed Monkeys: Adaptation to Seasonal Variations Through Energy Compensation and Thermogenesis

Integrative Zoology, EarlyView.
Based on metagenome‐assembled genomes (MAGs), the gut microbiota of the gray snub‐nosed monkeys recovered 1229 non‐redundant MAGs. The gut microbiota showed an enhanced capacity to produce energy substrates with increased conversion activity of these substrates during winter.

Food choice phenotypes : causes and consequences of habitual food selection [PDF]

, 2003
The primary aim of this thesis was to investigate the characteristics of individuals defined by their contrasting habitual selection of high fat and low fat foods. Previous studies have applied the term phenotype to this classification.

Sympathetic nerve innervation is required for beigeing in white fat

Physiological Reports, 2019
It is increasingly recognized that activation of beige adipocyte thermogenesis by pharmacological or genetic approaches increases energy expenditure and alleviates obesity.
