Adrenalectomy alters the sensitivity of the central nervous system melanocortin system [PDF]

, 2003
Removal of adrenal steroids by adrenalectomy (ADX) reduces food intake and body weight in rodents and prevents excessive weight gain in many genetic and dietary models of obesity. Thus, glucocorticoids appear to play a key role to promote positive energy

Melanocortin Pathways: Suppressed and Stimulated Melanocortin-4 Receptor (MC4R)

Physiological Research, 2020
Leptin-melanocortin pathway plays an essential role in the body weight regulation. Enhanced melanocortin signaling in the hypothalamus results in both decreased food intake and increased energy expenditure. The discovery of monogenic obesities with dysfunction of melanocortin-4 receptor (MC4R) greatly contributed to understanding of energy balance ...

Ring finger protein 11 inhibits melanocortin 3 and 4 receptor signaling

Frontiers in Endocrinology, 2016
Intact melanocortin signaling via the G protein-coupled receptors (GPCRs) melanocortin receptor 4 (MC4R) and melanocortin receptor 3 (MC3R) is crucial for body weight maintenance.

Melanocortin 1 receptor targeted imaging of melanoma with gold nanocages and positron emission tomography [PDF]

, 2018
Purpose: Melanoma is a lethal skin cancer with unmet clinical needs for targeted imaging and therapy. Nanoscale materials conjugated with targeting components have shown great potential to improve tumor delivery efficiency while minimizing undesirable ...

Inhibitory effect of the melanocortin receptor agonist melanotan-II (MTII) on feeding depends on dietary fat content and not obesity in rats on free-choice diets

Frontiers in Behavioral Neuroscience, 2015
Introduction: Conflicting data exist on sensitivity changes of the melanocortin system during diet-induced obesity. We hypothesized that melanocortin sensitivity depends on diet composition, in particular on the fat content rather than the level of ...

Modulation of social behavior by the agouti pigmentation gene [PDF]

, 2014
Agouti is a secreted neuropeptide that acts as an endogenous antagonist of melanocortin receptors. Mice and rats lacking agouti (called non-agouti) have dark fur due to a disinhibition of melanocortin signaling and pigment deposition in the hair follicle.

Observations on the evolution of the melanocortin receptor gene family: distinctive features of the melanocortin-2 receptor

Frontiers in Neuroscience, 2013
The melanocortin receptors are a gene family in the rhodopsin class of G protein-coupled receptors. Based on the analysis of several metazoan genome databases it appears that the melanocortin receptors are only found in chordates.

Understanding pseudo-albinism in sole (Solea senegalensis): a transcriptomics and metagenomics approach [PDF]

, 2019
Pseudo-albinism is a pigmentation disorder observed in flatfish aquaculture with a complex, multi-factor aetiology. We tested the hypothesis that pigmentation abnormalities are an overt signal of more generalised modifications in tissue structure and ...

Melanocortin-4 Receptors (MC4R)

AVERROUS: Jurnal Kedokteran dan Kesehatan Malikussaleh, 2023
Melanocortin 4 Receptors (MC4R) merupakan turunan senyawa G protein coupled-receptors (GPCRs). MC4R berperan dalam homeostasis energi, fungsi kardiovaskular, dan sistem reproduksi. Gen MC4R ini menyandi sekitar 332 asam amino dan terkespresi pada hipotalamus. MC4R salah satu protein transmembran dengan memiliki tujuh subtipe protein.

Development of a genetically encoded melanocortin sensor for high sensitivity in vivo imaging

Molecular Metabolism
Objective: The central melanocortin system, composed of peptides derived from pro-opiomelanocortin (POMC) such as the melanocyte-stimulating hormones (α-, β-, γ-MSH) and melanocortin 4 receptors (MC4R), along with the agouti-related protein (AgRP), plays
