Glucose Intake during the Neonatal Period Modulates the Central Melanocortin System with Breed-Specific Differences

The Journal of Poultry Science
Glucose is the primary substrate for cellular energy production, and its blood concentration is tightly regulated. This study investigated the effect of glucose supplementation during the first three days post-hatching on growth performance and ...

Alpha‐Synuclein Promotes Anterograde Vesicle Transport in Melanocytes and Melanoma Cells: A Pro‐Survival Function

Journal of the Chinese Chemical Society, EarlyView.
Model for how α‐syn modulates the positioning of endolysosomes in melanoma cells. (a) α‐syn tethers endolysosomes to the plasma membrane, a last step in anterograde transport. (b) Loss of α‐syn expression causes the loss of the tethering function, which leads to perinuclear vesicle clustering. Reproduced from the open access article.

Cutaneous Pigmentary Changes During Setmelanotide Therapy: Dermoscopic and Confocal Findings in Two Patients

JEADV Clinical Practice, EarlyView.
ABSTRACT Setmelanotide is a melanocortin‐4 receptor agonist approved for the treatment of rare forms of genetic obesity. Through off‐target activation of the melanocortin‐1 receptor, it may induce cutaneous pigmentation changes; however, data regarding its effects on melanocytic nevi remain limited.

Effectiveness and Safety of Setmelanotide in a Patient With a Heterozygous PCSK1 Deficiency

Obesity, EarlyView.
ABSTRACT Setmelanotide, a melanocortin 4 receptor (MC4R) agonist, is a promising pharmacological treatment option for people with rare monogenic obesity conditions affecting the leptin‐melanocortin signaling pathway, including proprotein convertase subtilisin/kexin type 1 (PCSK1) gene mutations.

MRAP2 regulates energy homeostasis by promoting primary cilia localization of MC4R

JCI Insight, 2023
The G protein–coupled receptor melanocortin-4 receptor (MC4R) and its associated protein melanocortin receptor–associated protein 2 (MRAP2) are essential for the regulation of food intake and body weight in humans.

Vascular effects of deletion of melanocortin-4 receptors in rats [PDF]

Physiological Reports, 2013
Obesity is a major cause of hypertension, but links between the obese and hypertensive states remain incompletely understood. A major component of cardiovascular function in obese individuals is a state of sympathoactivation. A postulated mechanism of this sympathoactivation is the activation of specific classes of neurons commonly associated with ...

Musculoskeletal Outcomes of Glucagon‐Like Peptide‐1 Receptor Agonists Versus Other Antiobesity Agents in Nondiabetic Adults

Obesity, EarlyView.
ABSTRACT Objective This study aimed to evaluate the association of glucagon‐like peptide‐1 receptor agonists (GLP‐1 RAs) with risks of osteoporosis, major osteoporotic fractures, and degenerative musculoskeletal disorders in nondiabetic adults with obesity compared with other obesity medications.

SURMOUNT‐REAL UK: A Pragmatic Randomized Clinical Trial to Assess the Effectiveness of Tirzepatide in Adults With Obesity

Obesity, EarlyView.
ABSTRACT Objective SURMOUNT‐REAL UK will evaluate the effectiveness of tirzepatide when offered in addition to standard‐of‐care (SoC) in adults with Class I obesity (BMI ≥ 30 and ≤ 34.9 kg/m2) and without diabetes in a UK primary care setting. Methods A 5‐year, phase 4, multicenter, open‐label, pragmatic randomized clinical trial is enabled through ...

Monogenic and syndromic obesity in children: Clinical recognition, genetics, and precision management

Pediatric Investigation, EarlyView.
Monogenic and syndromic obesity in children often arises from defects in the leptin–melanocortin pathway. Understanding these rare genetic causes not only clarifies mechanisms of appetite regulation but also enables precision therapies, offering hope beyond lifestyle interventions.

Fine‐scale spatial variation in eastern grey squirrel melanism across a complex urban landscape

Journal of Animal Ecology, EarlyView.
By sampling 197 parks, the study demonstrates how natural geography creates divergence within cities. The findings reveal that the St. Lawrence River and its tributaries act as barriers, disrupting urban melanism clines in grey squirrels. Ultimately, the research indicates that natural features still dictate evolutionary rules in anthropogenic ...
