Loss of MyoD Promotes Fate Transdifferentiation of Myoblasts Into Brown Adipocytes

EBioMedicine, 2017
Brown adipose tissue (BAT) represents a promising agent to ameliorate obesity and other metabolic disorders. However, the abundance of BAT decreases with age and BAT paucity is a common feature of obese subjects. As brown adipocytes and myoblasts share a

Adipocyte Myoglobin Is a Determinant of Energy Expenditure and a Potential Target to Limit Obesity

Advanced Science, EarlyView.
Myoglobin, known as a muscle oxygen‐carrying protein, is shown to play a key role in fat cells that burn energy. Loss of myoglobin reduces the body's ability to generate heat and increases obesity risk, while restoring it improves metabolism. The study identifies myoglobin as a regulator of fat burning and a potential target to enhance energy ...

Longitudinal Single‐Axon‐Resolution Imaging of Peripheral Nerve Injury Response in Mice Using an Optical Window Implant

Advanced Science, EarlyView.
A minimally invasive optical window enables stable, long‐term imaging of peripheral nerves in vivo at single‐axon resolution. Dynamic processes of degeneration, regeneration, and cellular remodeling are visualized across multiple time scales within the same nerve region, providing a unique platform to study a variety of anatomical and molecular events ...

Transcriptomic signatures of cold acclimated adipocytes reveal CXCL12 as a Brown autocrine and paracrine chemokine

Molecular Metabolism
Besides its thermogenic capacity, brown adipose tissue (BAT) performs important secretory functions that regulate metabolism. However, the BAT microenvironment and factors involved in BAT homeostasis and adaptation to cold remain poorly characterized. We

Regulation of white and brown adipocyte differentiation by RhoGAP DLC1. [PDF]

PLoS ONE, 2017
Adipose tissues constitute an important component of metabolism, the dysfunction of which can cause obesity and type II diabetes. Here we show that differentiation of white and brown adipocytes requires Deleted in Liver Cancer 1 (DLC1), a Rho GTPase ...

Recent insights into the molecular mechanisms of simultaneous fatty acid oxidation and synthesis in brown adipocytes

Frontiers in Endocrinology, 2023
Brown adipocytes is a specialized fat cell that dissipates nutrient-derived chemical energy in the form of heat, instead of ATP synthesis. This unique feature provides a marked capacity for brown adipocyte mitochondria to oxidize substrates independent ...

A Second Pathogenic Protein, PolyGN2C‐iso2, Reveals a Dual‐Protein Pathology in Neuronal Intranuclear Inclusion Disease

Advanced Science, EarlyView.
This study reveals that NOTCH2NLC transcript variant 2 generates PolyGN2C‐iso2, an aggregating protein present within intranuclear inclusions of NIID patient tissues. A novel mouse model expressing PolyGN2C‐iso2 recapitulates white matter abnormalities and cognitive deficits, mechanistically linked to mitochondrial dysfunction. These findings support a

Berardinelli–Seip congenital lipodystrophy 2/SEIPIN determines brown adipose tissue maintenance and thermogenic programing

Molecular Metabolism, 2020
Objective: Understanding the mechanisms that control brown adipose tissue (BAT) mass and functionality is crucial for our understanding of how the disruption of energy homeostasis leads to obesity. Bernerdinali Seip Congenital Lipodystrophy (BSCL) type 2

Adaptive thermogenesis in brown adipose tissue involves activation of pannexin-1 channels

Molecular Metabolism, 2021
Objective: Brown adipose tissue (BAT) is specialized in thermogenesis. The conversion of energy into heat in brown adipocytes proceeds via stimulation of β-adrenergic receptor (βAR)-dependent signaling and activation of mitochondrial uncoupling protein 1

SnRNA‐seq reveals cellular heterogeneity and proliferation mechanisms in limb venous malformations

Animal Models and Experimental Medicine, EarlyView.
To dissect the cellular heterogeneity and invasive mechanisms of limb venous malformations (VMs), this study first obtained tissue samples from four patients with VMs and four normal controls (NC). Single‐nucleus suspension was prepared, followed by transcriptome library construction and sequencing. After pretreatment, quality control, standardization,
