Histone demethylase JMJD1A coordinates acute and chronic adaptation to cold stress via thermogenic phospho-switch

open access: yesNature Communications, 2018
JMJD1A is essential for thermogenic gene induction in brown adipose tissue. Here the authors show that white adipose tissue beige-ing requires both β-adrenergic-dependent phosphorylation of S265 and demethylation activity of JMJD1A while brown adipose ...

Adipocytes and Stromal Cells Regulate Brown Adipogenesis Through Secretory Factors During the Postnatal White-to-Brown Conversion of Adipose Tissue in Syrian Hamsters

open access: yesFrontiers in Cell and Developmental Biology, 2021
Brown adipose tissue (BAT) is a specialized tissue that regulates non-shivering thermogenesis. In Syrian hamsters, interscapular adipose tissue is composed primarily of white adipocytes at birth, which is converted to BAT through the proliferation and ...

Gut Microbiota Colonization in Early Life Influences Susceptibility to Adulthood Hepatic Lipid Accumulation in High‐Fat‐Diet‐Fed Mice

open access: yesAdvanced Science, EarlyView.
This study indicates that perinatal antibiotic exposure elevates susceptibility to high‐fat‐diet‐induced hepatic lipid accumulation via disrupting early‐life gut microbiota colonization. The decreased Lactobacillus colonization inhibits primary‐to‐secondary bile acid conversion, lowering secondary bile acids, enhancing adulthood intestinal lipid ...

Multiple regulatory steps are involved in the control of lipoprotein lipase activity in brown adipose tissue.

open access: yesJournal of Lipid Research, 1996
Lipoprotein lipase (LPL) supplies brown adipose tissue with fatty acids for nonshivering thermogenesis. In brown adipose tissue of the Djungarian hamster we studied i) the molecular mechanisms involved in cold-induced stimulation of LPL activity, ii) the

Asprosin‐FABP5 Interaction Modulates Mitochondrial Fatty Acid Oxidation through PPARα Contributing to MASLD Development

open access: yesAdvanced Science, EarlyView.
Aided by FABP5, abnormally elevated asprosin in hepatocytes enters the nucleus, targets and inhibits PPARα binding to the CPT1A promoter, thereby suppressing FAO. Circulating asprosin exacerbates insulin resistance, collectively driving MASLD progression.

Triiodothyronine (T3) promotes brown fat hyperplasia via thyroid hormone receptor α mediated adipocyte progenitor cell proliferation

open access: yesNature Communications, 2022
Thyroid hormone (TH) action regulates brown adipose tissue thermogenic capacity through incompletely understood mechanisms. Here the authors report that T3, the active form of TH, increases thermogenic capacity via thyroid hormone receptor α-mediated ...

Ortho-positronium Lifetime For Soft-tissue Classification [PDF]

open access: yesScientific Reports 14.1 (2024): 21155
The objective of this work is to showcase the ortho-positronium lifetime as a probe for soft-tissue characterization. We employed positron annihilation lifetime spectroscopy to experimentally measure the three components of the positron annihilation lifetime para-positronium (p-Ps), positron, and ortho-positronium (o-Ps) for three types of porcine, non-

Inhibition of Ferroptosis Delays Aging and Extends Healthspan Across Multiple Species

open access: yesAdvanced Science, EarlyView.
This study identifies ferroptosis as a key driver of cellular senescence, with its inhibition delaying aging and extending healthspan across species. During senescence, ferroptosis worsens, increasing oxidative stress and lipid peroxidation, which accelerate aging.

MTCH2 Suppresses Thermogenesis by Regulating Autophagy in Adipose Tissue

open access: yesAdvanced Science, EarlyView.
This study demonstrates that MTCH2 acts as an evolutionarily conserved regulator of energy homeostasis across Drosophila, rodents, and humans. Adipose‐specific MTCH2 ablation enhances brown/beige adipose thermogenesis through Bcl‐2‐dependent autophagy, promoting energy expenditure and counteracting obesity‐associated metabolic disorders. These findings

Activation of brown adipose tissue in hypothyroidism [PDF]

open access: yesAnnals of Medicine, 2015
Brown adipose tissue (BAT) attracts growing interest as a potential therapeutic target for obesity and diabetes. Hyperthyroidism is well-known to increase BAT activity, but the role of hypothyroidism is controversial. We aimed to investigate the association between different thyroid hormone (TH) states and BAT activity.FDG-PET studies were ...
