Phosphorylation of Beta-3 adrenergic receptor at serine 247 by ERK MAP kinase drives lipolysis in obese adipocytes

Molecular Metabolism, 2018
Objective: The inappropriate release of free fatty acids from obese adipose tissue stores has detrimental effects on metabolism, but key molecular mechanisms controlling FFA release from adipocytes remain undefined.

EH Domain-Containing 2 Deficiency Restricts Adipose Tissue Expansion and Impairs Lipolysis in Primary Inguinal Adipocytes

Frontiers in Physiology, 2021
Lipid uptake can be facilitated via caveolae, specific plasma membrane invaginations abundantly expressed in adipocytes. The dynamin-related protein EH domain-containing 2 (EHD2) stabilizes caveolae at the cell surface.

Opposing Actions of Adrenocorticotropic Hormone and Glucocorticoids on UCP1-Mediated Respiration in Brown Adipocytes

Frontiers in Physiology, 2019
Brown fat is a potential target in the treatment of metabolic disorders as recruitment and activation of this thermogenic organ increases energy expenditure and promotes satiation.

Counter effects of Asiaticosids-D through putative neurotransmission on rotenone induced cerebral ganglionic injury in Lumbricus terrestris

IBRO Reports, 2019
Asiaticoside-D (AD) was shown to efficacy of ganglionic degenerated Lumbricus terrestris as a pioneering observation in our earlier research. Though, extract molecular mechanisms of AD for degenerative diseases (DDs) remains largely unknown.

Norepinephrine Regulation of Adrenergic Receptor Expression, 5’ AMP-Activated Protein Kinase Activity, and Glycogen Metabolism and Mass in Male Versus Female Hypothalamic Primary Astrocyte Cultures

ASN Neuro, 2020
Norepinephrine (NE) control of hypothalamic gluco-regulation involves astrocyte-derived energy fuel supply. In male rats, exogenous NE regulates astrocyte glycogen metabolic enzyme expression in vivo through 5’-AMP-activated protein kinase (AMPK ...

Molecular determinants of signal transduction in tropomyosin receptor kinases

FEBS Open Bio, EarlyView.
Tropomyosin receptor kinases control critical neuronal functions, but how do the same receptors produce diverse cellular responses? This review explores the structural mechanisms behind Trk signaling diversity, focusing on allosteric modulation and ligand bias.

Norepinephrine Induces Sertoli Cell Ferroptosis via Receptors Desensitization Causing Stress‐Related Male Reproductive Dysfunction

Advanced Science, EarlyView.
Psychological stress activates the sympathetic–adrenal axis, elevating norepinephrine (NE) and suppressing reproductive hormones, thereby impairing male reproduction. Excess NE overactivates and desensitizes β‐adrenergic receptors (β‐ARs), triggering Sertoli cell ferroptosis and disrupting spermatogenesis.

Preservation of ALYREF Phase Separation Mitigates Doxorubicin‐Induced Cardiomyocyte DNA Damage and Cardiotoxicity

Advanced Science, EarlyView.
Binding of Doxorubicin to ALYREF disrupts its phase‐separated condensate and induces DNA damage and apoptosis in cardiomyocytes Abstract The clinical utility of the anticancer agent doxorubicin (DOX) is limited by its dose‐dependent cardiotoxicity.

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

Advanced Science, EarlyView.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...
