Pathophysiology of melanocortin receptors and their accessory proteins. [PDF]

open access: yes, 2018
The melanocortin receptors (MCRs) and their accessory proteins (MRAPs) are involved in regulation of a diverse range of endocrine pathways. Genetic variants of these components result in phenotypic variation and disease. The MC1R is expressed in skin and

Noradrenergic inhibition of definitive POMC neurons through direct and indirect mechanisms

open access: yesJournal 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 ...

Posttranslational modifications of proopiomelanocortin in vertebrates and their biological significance

open access: yesFrontiers in Endocrinology, 2013
Proopiomelanocortin (POMC) is the precursor of several peptide hormones generated in the pituitary gland. After biosynthesis, POMC undergoes several posttranslational modifications, including proteolytic cleavage, acetylation, amidation, phosphorylation,

Prenatal programming of postnatal obesity: fetal nutrition and the regulation of leptin synthesis and secretion before birth [PDF]

open access: yes, 2004
Exposure to either an increased or decreased level of intrauterine nutrition can result in an increase in adiposity and in circulating leptin concentrations in later life.

The Double‐Edged Sword of Gestational Insulin Resistance: Navigating Maternal Adaptation and Its Risks for Pregnancy and Offspring Health

open access: yesObesity Reviews, Volume 27, Issue 4, April 2026.
ABSTRACT Although much research focuses on the effects of hyperglycemia during pregnancy on maternal and offspring health, this narrative review specifically centers on the role of insulin resistance (IR) in pregnancy complications and offspring long‐term health.

Differential expression of POMC-processing genes in corticotroph tumors

open access: yesEndocrine Oncology
Objective: Corticotroph tumors (CTs) derive from the TBX19 lineage and are functioning (FCTs) or nonfunctioning (NFCTs). In FCTs, the main pathogenic variants are found in USP8, enhancing proopiomelanocortin (POMC) transcription through epidermal growth ...

Relative number and distribution of murine hypothalamic proopiomelanocortin neurons innervating distinct target sites. [PDF]

open access: yesPLoS ONE, 2011
Proopiomelanocortin (POMC) neurons send projections widely throughout the brain consistent with their role in regulating numerous homeostatic processes and mediating analgesia and reward.

Expression of genes related to the hypothalamic-pituitary-adrenal axis in murine fetal lungs in late gestation [PDF]

open access: yes, 2010
Background Lung maturation is modulated by several factors, including glucocorticoids. Expression of hypothalamic-pituitary-adrenal (HPA) axis-related components, with proposed or described local regulatory systems analogous to the HPA axis, was reported

The role of agomelatine in appetite regulation and body weight in rats

open access: yesExperimental Physiology, Volume 111, Issue 4, Page 1808-1818, 1 April 2026.
Abstract The hypothalamic nuclei play a central role in the synthesis of anorexigenic and orexigenic neuropeptides, which are regulated by peripheral hormones, like leptin and ghrelin. Melatonergic receptors (MT1/MT2) are prominently expressed in the arcuate nucleus of the hypothalamus – an essential hub for appetite control – and in peripheral ...

Proopiomelanocortin Expression in both GABA and Glutamate Neurons [PDF]

open access: yesThe Journal of Neuroscience, 2009
Proopiomelanocortin (POMC) neurons have been intensively studied because of their essential role in regulating energy balance and body weight. Many effects of POMC neurons can be attributed to their release of cognate neuropeptides from secretory granules in axon terminals.
