Motivational dysregulation with melanocortin 4 receptor haploinsufficiency. [PDF]

NeuroImmune Pharm Ther, 2022
AbstractObesity, by any standard, is a global health crisis. Both genetic and dietary contributions to the development and maintenance of obesity were integral factors of our experimental design. As mutations of the melanocortin 4 receptors (MC4R) are the leading monogenetic cause of obesity, MC4R haploinsufficient rats were fed a range of dietary fat (

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.

The complicated clinical course in a case of atypical lipodystrophy after development of neutralizing antibody to metreleptin: treatment with setmelanotide

Endocrinology, Diabetes & Metabolism Case Reports, 2020
A patient with atypical partial lipodystrophy who had a transient initial response to metreleptin experienced acute worsening of her metabolic state when neutralizing antibodies against metreleptin appeared.

Differential Signaling Profiles of MC4R Mutations with Three Different Ligands [PDF]

, 2020
The melanocortin 4 receptor (MC4R) is a key player in hypothalamic weight regulation and energy expenditure as part of the leptin-melanocortin pathway. Mutations in this G protein coupled receptor (GPCR) are the most common cause for monogenetic obesity,

Melanocortin-4 receptor–regulated energy homeostasis [PDF]

Nature Neuroscience, 2016
The melanocortin system provides a conceptual blueprint for the central control of energetic state. Defined by four principal molecular components--two antagonistically acting ligands and two cognate receptors--this phylogenetically conserved system serves as a prototype for hierarchical energy balance regulation.

The Melanocortin-4 Receptor Integrates Circadian Light Cues and Metabolism [PDF]

, 2015
The melanocortin system directs diverse physiological functions from coat color to body weight homoeostasis. A commonality among melanocortin-mediated processes is that many animals modulate similar processes on a circannual basis in response to longer ...

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 ...

Promiscuity among the MRAPs. [PDF]

, 2017
The melanocortin 2 receptor accessory protein (MRAP) was originally discovered to be an essential co-receptor for the ACTH receptor/melanocortin 2 receptor, and it physically interacts with this receptor and is required for receptor trafficking and ...

Melanocortin 4 Receptor Becomes an ACTH Receptor by Coexpression of Melanocortin Receptor Accessory Protein 2 [PDF]

Molecular Endocrinology, 2013
Melanocortin 2 receptor (MC2R) is the only canonical ACTH receptor. Its functional expression requires the presence of an accessory protein, known as melanocortin receptor 2 accessory protein 1 (MRAP1). The vertebrate genome exhibits a paralogue gene called MRAP2, which is duplicated in zebrafish (MRAP2a and MRAP2b), although its function remains ...

The melanocortin pathway and energy homeostasis: From discovery to obesity therapy

Molecular Metabolism, 2021
Background: Over the past 20 years, insights from human and mouse genetics have illuminated the central role of the brain leptin-melanocortin pathway in controlling mammalian food intake, with genetic disruption resulting in extreme obesity, and more ...
