Signal Transduction and Pathogenic Modifications at the Melanocortin-4 Receptor: A Structural Perspective [PDF]

, 2019
The melanocortin-4 receptor (MC4R) can be endogenously activated by binding of melanocyte-stimulating hormones (MSH), which mediates anorexigenic effects. In contrast, the agouti-related peptide (AgRP) acts as an endogenous inverse agonist and suppresses

Decreased RYR2 Cluster Size and Abnormal SR Ca2+ Release Contribute to Arrhythmogenesis in TMEM43‐Related ARVC

Advanced Science, EarlyView.
The TMEM43 ‐ P386S mutation causes arrhythmogenic right ventricular cardiomyopathy (ARVC) by mislocalizing itself from nuclear envelope (NE) to cytoplasm, disrupting lamin B2 (a novel TMEM43 interactor) localization, NE integrity and chromatin accessibility, causing hyper ‐ phosphorylation and reduced expression/clustering of ryanodine receptor type 2 (

Aripiprazole induced priapism: A case report

Archives of Mental Health, 2015
Background: Priapism is a urologic emergency representing a true disorder of penile erection that persists beyond or is unrelated to sexual interest or stimulation. Variety of drugs is known to produce priapism, including psychotropics. Case description:

Aging and aerobic fitness affect the contribution of noradrenergic sympathetic nerves to the rapid cutaneous vasodilator response to local heating [PDF]

, 2011
Sedentary aging results in a diminished rapid cutaneous vasodilator response to local heating. We investigated whether this diminished response was due to altered contributions of noradrenergic sympathetic nerves; assessing 1) the age-related decline and,

Combining Adipose‐Derived Stromal Cell Spheroids and Melt Electrowritten Scaffolds for a 3D Adipose Model Mimicking Structure and Function of Fat Tissue

Advanced NanoBiomed Research, EarlyView.
A 3D adipose tissue model is fabricated by combining melt electrowritten scaffolds with multicellular adipose‐derived stromal cell spheroids. The resulting constructs are characterized by a coherent, tissue‐like matrix. The lipid droplet size is tunable by oleic acid supplementation, reaching native‐like diameters.

Histamine stimulates the proliferation of small and large cholangiocytes by activation of both IP3/Ca2+ and cAMP-dependent signaling mechanisms [PDF]

, 2012
Although large cholangiocytes exert their functions by activation of cyclic adenosine 3',5'-monophosphate (cAMP), Ca(2+)-dependent signaling regulates the function of small cholangiocytes. Histamine interacts with four receptors, H1-H4HRs.

Trends in first‐line monotherapy and combination therapy for hypertension in UK primary care

British Journal of Clinical Pharmacology, EarlyView.
Aims Debate remains about the optimal initial treatment strategy for hypertension. Most guidelines recommend first‐line combination therapy for most patients. However, the UK's National Institute for Health and Care Excellence recommends first‐line monotherapy for all patients.

The Role of Alpha-adrenergic Receptor Mechanism in Ejaculation

The Tohoku Journal of Experimental Medicine, 1972
The effects of autonomic drugs on seminal emission and ejaculation were investigated in mongrel dogs. Changes in the posterior urethral pressure (posterior urethrogram) and the volume of seminal emission during continuous hypogastric nerve stimulation were measured in test animals.

The Allosteric Mechanism of G‐Protein‐Coupled Receptors is Induced Fit, Not Conformational Selection

BioEssays, EarlyView.
Allosteric signaling of G‐protein‐coupled receptors (GPCRs) involves a population shift from inactive to active receptor conformations upon binding of ligand agonists. Kinetic and structural data indicate that this population shift is induced by ligand binding to inactive receptor conformations prior to the conformational change from inactive to active.

The heartbreak of depression: 'Psycho-cardiac' coupling in myocardial infarction [PDF]

, 2017
Ample evidence identifies strong links between major depressive disorder (MDD) and both risk of ischemic or coronary heart disease (CHD) and resultant morbidity and mortality. The molecular mechanistic bases of these linkages are poorly defined. Systemic
