ABSTRACT Aim Glucagon is a key regulator of glucose and energy metabolism, yet the dose–response effects of glucagon on markers of metabolism in humans are not fully characterised. We investigated the dose‐dependent effects of glucagon on glucose metabolism, β‐cell secretion and markers of hepatic metabolism in healthy adults.

ATHENA: A Phase 3, Open-Label Study Of The Safety And Effectiveness Of Oliceridine (TRV130), A G-Protein Selective Agonist At The µ-Opioid Receptor, In Patients With Moderate To Severe Acute Pain Requiring Parenteral Opioid Therapy. [PDF]
Background:Pain management with conventional opioids can be challenging due to dose-limiting adverse events (AEs), some of which may be related to the simultaneous activation of β-arrestin (a signaling pathway associated with opioid-related AEs) and G ...

Lock, relax, load, and shoot: a molecular perspective on Nedd4 regulation
Structural basis of inactive and active states of the Nedd4 HECT E3 ligase subfamily, following a ‘lock, relax, load, and shoot’ mechanism. In the locked, autoinhibited state, intramolecular domain interactions restrain the HECT domain. Relaxation releases these restraints, allowing loading of ubiquitin onto the catalytic cysteine, followed by the ...

Concepts of GPCR-controlled navigation in the immune system
G-protein-coupled receptor (GPCR) signaling is essential for the spatiotemporal control of leukocyte dynamics during immune responses. For efficient navigation through mammalian tissues, most leukocyte types express more than one GPCR on their surface ...

Spatiotemporal dynamics of β‐arrestin‐mediated Src activation in 5‐HT7 receptor signaling pathway
GPCRs induce distinct cellular responses via G protein‐ or β‐arrestin‐mediated signaling pathways. This study revealed that β‐arrestin‐biased 5‐HT7R ligand induces slow, sustained Src activation, contrasting with transient G protein‐mediated activation.

Innovations in Obesity Treatment: Beyond Adipose Tissue Dysfunction
Obesity drives chronic inflammation, insulin resistance, type 2 diabetes, and cancer development through adipocyte dysfunction. Addressing this multisystemic disorder requires integrated strategies beyond diet and exercise, such as thermogenesis activation via menthol or capsinoids and appetite control through GLP‐1/GIP agonists and neuromodulation to ...

β-arrestin 1 regulates β2-adrenergic receptor-mediated skeletal muscle hypertrophy and contractility
Background β2-adrenergic receptors (β2ARs) are the target of catecholamines and play fundamental roles in cardiovascular, pulmonary, and skeletal muscle physiology.

ABSTRACT Equine melanocytic neoplasms (EMN) are aggressive tumours characterised by high metastatic potential and limited therapeutic options available. However, the molecular mechanisms underlying their progression remain poorly understood. This study therefore presents the integrative phosphoproteomic analysis of EMN tissue, with the aim of ...

Troglitazone stimulates beta-arrestin-dependent cardiomyocyte contractility via the angiotensin II type 1A receptor. [PDF]
Peroxisome proliferator-activated receptor gamma (PPAR gamma) agonists are commonly used to treat cardiovascular diseases, and are reported to have several effects on cardiovascular function that may be due to PPAR gamma-independent signaling events ...

Evidence for a Two‐Step Model for Activation of GPR25 by the Chemoattractant CXCL17
ABSTRACT CXCL17 was recently reported to activate GPR25, a receptor expressed by T‐regulatory cells. Although classified as a chemokine, the activity of CXCL17 is ablated by minor C‐terminal truncation, suggesting a novel mode of receptor activation. We set out to test this hypothesis by mutagenesis. GPR25 was expressed in the murine pre‐B cell line L1.
