Chemogenetic Excitation of Ventromedial Hypothalamic Steroidogenic Factor 1 (SF1) Neurons Increases Muscle Thermogenesis in Mice

Biomolecules
Allostatic adaptations to a perceived threat are crucial for survival and may tap into mechanisms serving the homeostatic control of energy balance. We previously established that exposure to predator odor (PO) in rats significantly increases skeletal ...

Nested Selves: Self‐Organization and Shared Markov Blankets in Prenatal Development in Humans

Topics in Cognitive Science, EarlyView., 2023
Abstract The immune system is a central component of organismic function in humans. This paper addresses self‐organization of biological systems in relation to—and nested within—other biological systems in pregnancy. Pregnancy constitutes a fundamental state for human embodiment and a key step in the evolution and conservation of our species. While not

SIRT7 suppresses energy expenditure and thermogenesis by regulating brown adipose tissue functions in mice

Nature Communications, 2022
Sirtuins have been reported to positively regulate brown adipose tissue thermogenesis. Here the authors report that brown adipocytic SIRT7 suppresses whole-body energy expenditure and thermogenesis in mice, potentially by attenuating batokine gene ...

The Liver as a Hub in Thermogenesis [PDF]

Cell Metabolism, 2017
Manipulating thermogenesis could increase energy expenditure and improve metabolism. Brown fat is a major site of nonshivering thermogenesis, but other tissues, notably muscle and liver, can contribute to cold adaptation. In this issue, Simcox et al.

Gsα deficiency in the dorsomedial hypothalamus leads to obesity, hyperphagia, and reduced thermogenesis associated with impaired leptin signaling

Molecular Metabolism, 2019
Objective: Gsα couples multiple receptors, including the melanocortin 4 receptor (MC4R), to intracellular cAMP generation. Germline inactivating Gsα mutations lead to obesity in humans and mice.

MFSD7C switches mitochondrial ATP synthesis to thermogenesis in response to heme

Nature Communications, 2020
Mitochondria maintain a balance between thermogenesis and ATP synthesis, but how this is coordinated is largely unknown. Here, the authors show that MFSD7C coordinates ATP synthesis and thermogenesis in response to heme by directly binding to electron ...

microRNA-33 maintains adaptive thermogenesis via enhanced sympathetic nerve activity

Nature Communications, 2021
Adaptive thermogenesis is regulated by central neuronal circuits. Here, the authors show that microRNA-33 in the brain contributes to the maintenance of brown adipose tissue thermogenesis and whole-body energy balance via enhanced sympathetic nerve tone,

PexRAP inhibits PRDM16-mediated thermogenic gene expression [PDF]

, 2017
How the nuclear receptor PPARγ regulates the development of two functionally distinct types of adipose tissue, brown and white fat, as well as the browning of white fat, remains unclear.

Is thermogenesis really needed for brown adipose tissue–mediated metabolic benefit?

The Journal of Clinical Investigation, 2022
Brown adipose tissue (BAT) dissipates energy in the form of heat and functions as a metabolic sink for lipids, glucose, and branched-chain amino acids. Enhanced BAT thermogenesis is thought to tightly couple with beneficial energy metabolism. However, in

A Third Variable in Obesity: The Effects of Brown Adipose Tissue on Thermogenesis

, 1981
Approaches to weight management which consider only energy intake and/or expenditure do not consistently lead to favorable outcomes. A third variable, thermogenesis, must also be considered in a comprehensive understanding of obesity· Three types of ...
