Novel Agouti-Related-Protein-Based Melanocortin-1 Receptor Antagonist
The melanocortin receptors are G-protein coupled receptors (GPCRs) that activate the cAMP signal transduction pathway and are stimulated by the melanocortin agonist α-melanocyte stimulating hormone (α-MSH).

Neuroendocrine and Molecular Interactions in Eating Disorders [PDF]
There are three basic pillars for the development of eating disorders: genetic predisposition, neuro-endocrine-molecular changes in the brain and metabolic response to it.

Plasma Levels of Agouti-Related Protein Are Increased in Obese Men [PDF]
To investigate the relationship between peripheral blood levels of agouti-related protein (AGRP) and various parameters of obesity, we measured the plasma level of AGRP in 15 obese and 15 nonobese men and evaluated its relationship with body mass index (BMI), body fat weight, and visceral, sc, and total fat areas measured by computed tomography ...

Agouti signal protein regulation in human melanoma cells
Production of the pigment eumelanin is controlled by alpha-melanocyte stimulating hormone (alpha-MSH) stimulation of melanocortin 1 receptor (Mc1r), whereas production of pheomelanin results from agouti antagonism of alpha-MSH signalling through Mc1r ...

Transcriptional Regulation of Agouti-Related Protein (Agrp) in Transgenic Mice [PDF]
AbstractAgouti-related protein (Agrp) encodes a hypothalamic neuropeptide that promotes positive energy balance by stimulating food intake and reducing energy expenditure. Agrp expression in the brain is restricted to neurons within the arcuate nucleus of the hypothalamus, and expression levels are elevated as a consequence of food deprivation.

Circadian rhythm disruption impairs metabolic regulation, appetite control, and vascular function, promoting obesity and cardiovascular diseases. Evidence highlights a bidirectional relationship where metabolic disorders further disturb circadian timing.

The role of agouti-related protein in regulating body weight
Defects in signaling by leptin, a hormone produced primarily by adipose tissue that informs the brain of the body's energy reserves, result in obesity in mice and humans. However, the majority of obese humans do not have abnormalities in leptin or its receptor but instead exhibit leptin resistance that could result from defects in downstream mediators ...

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.
