Folding, misfolding, and regulation of intracellular traffic of G protein‐coupled receptors involved in the hypothalamic–pituitary–gonadal axis

Andrology, EarlyView.
Abstract Background G protein‐coupled receptors are a large and functionally diverse family of membrane receptors involved in a number of biological processes. Like other proteins, G protein‐coupled receptors need to be properly folded in order to traffic to the plasma membrane and interact with agonist.

A multi‐omics investigation of sarcopenia and frailty: Integrating genomic, epigenomic and telomere length data

Experimental Physiology, EarlyView.
Abstract Sarcopenia and frailty are complex geriatric syndromes influenced by a combination of genetic and environmental factors. Recent studies suggest that specific genetic variants, DNA methylation patterns and shortened telomeres are associated with age‐related diseases and might contribute to the development of both sarcopenia and frailty. In this

Tonic ubiquitination of the central body weight regulator melanocortin receptor 4 (MC4R) promotes its constitutive exit from cilia.

PLoS Biology
The G protein-coupled receptor (GPCR) melanocortin receptor 4 (MC4R) is an essential regulator of body weight homeostasis. MC4R is unusual among GPCRs in that its activity is regulated by 2 opposing physiological ligands, the agonist ⍺-MSH and the ...

Joint TOS/OMA/OAC Expert Guidance Statement on the Pharmacological Management of United States Adults With Overweight or Obesity Using the GRADE Approach

Obesity, Volume 34, Issue 4, Page 851-870, April 2026.
Guidance recommendations by TOS/OMA/OAC for the use of obesity medications to treat obesity and its complications. ABSTRACT Background Obesity affects over 40% of US adults, with severe obesity on the rise. Despite recognition of obesity as a chronic disease, it remains underdiagnosed and undertreated.

Activation of melanocortin receptor 4 with RO27-3225 attenuates neuroinflammation through AMPK/JNK/p38 MAPK pathway after intracerebral hemorrhage in mice

Journal of Neuroinflammation, 2018
Background Neuroinflammation plays an important role in the pathogenesis of intracerebral hemorrhage (ICH)-induced secondary brain injury. Activation of melanocortin receptor 4 (MC4R) has been shown to elicit anti-inflammatory effects in many diseases ...

Investigation of a genome wide association signal for obesity: synthetic association and haplotype analyses at the melanocortin 4 receptor gene locus. [PDF]

PLoS ONE, 2010
BACKGROUND: Independent genome-wide association studies (GWAS) showed an obesogenic effect of two single nucleotide polymorphisms (SNP; rs12970134 and rs17782313) more than 150 kb downstream of the melanocortin 4 receptor gene (MC4R).

New mutations at the imprinted Gnas cluster show gene dosage effects of Gsα in postnatal growth and implicate XLαs in bone and fat metabolism, but not in suckling [PDF]

, 2012
The imprinted Gnas cluster is involved in obesity, energy metabolism, feeding behavior, and viability. Relative contribution of paternally expressed proteins XLαs, XLN1, and ALEX or a double dose of maternally expressed Gsα to phenotype has not been ...

Noradrenergic inhibition of definitive POMC neurons through direct and indirect mechanisms

Journal of Neuroendocrinology, Volume 38, Issue 4, April 2026.
Norepinephrine and the α2‐adrenoceptor agonist UK 14,304 robustly inhibit definitive arcuate POMC neurons. Direct inhibition is mediated by ADRA2A‐dependent activation of potassium conductances, while additional indirect mechanisms also contribute. In vivo, inducible POMC‐specific Adra2a deletion minimally affects energy balance and modestly impairs ...

A novel mutation Thr162Arg of the melanocortin 4 receptor gene in a Spanish children and adolescent population [PDF]

, 2007
Objective  The melanocortin 4 receptor gene (MC4R) is involved in body weight regulation. While many studies associated MC4R mutations with childhood obesity, information on MC4R mutations in Spanish children and adolescents is lacking. Our objective was

Dysfunctional TRIM31 of POMC Neurons Provokes Hypothalamic Injury and Peripheral Metabolic Disorder under Long‐Term Fine Particulate Matter Exposure

Advanced Science, Volume 13, Issue 14, 9 March 2026.
Particulate matter ≤2.5 µm (PM2.5) elevates risks of neurological and chronic metabolic diseases, but the underlying mechanisms linking PM2.5‐induced central nervous system (CNS) injury to metabolic dysfunction remain unclear. Hypothalamic pro‐opiomelanocortin‐expressing (POMC+) neurons regulate systemic metabolic homeostasis, and tripartite motif ...
