Proopiomelanocortin (POMC), the ACTH/melanocortin precursor, is secreted by human epidermal keratinocytes and melanocytes and stimulates melanogenesis.
Proopiomelanocortin (POMC) can be processed to ACTH and melanocortin peptides. However, processing is incomplete in some tissues, leading to POMC precursor release from cells. This study examined POMC processing in human skin and the effect of POMC on the melanocortin-1 receptor (MC-1R) and melanocyte regulation. POMC was secreted by both human epidermal keratinocytes (from 5 healthy donors) an...
متن کاملHypothalamic proopiomelanocortin (POMC) neurons have a cholinergic phenotype.
Neuronal networks originating in the hypothalamic arcuate nucleus play fundamental roles in the control of energy balance. Neuropeptide Y (NPY)-producing neurons in the arcuate nucleus stimulate food intake, whereas arcuate nucleus neurons that release the proopiomelanocortin (POMC)-derived peptide alpha-melanocyte-stimulating hormone (alpha-MSH) potently reduce food intake. Relatively little a...
متن کاملThe role of proopiomelanocortin (POMC) neurones in feeding behaviour
The precursor protein, proopiomelanocortin (POMC), produces many biologically active peptides via a series of enzymatic steps in a tissue-specific manner, yielding the melanocyte-stimulating hormones (MSHs), corticotrophin (ACTH) and beta-endorphin. The MSHs and ACTH bind to the extracellular G-protein coupled melanocortin receptors (MCRs) of which there are five subtypes. The MC3R and MC4R sho...
متن کامل60 YEARS OF POMC: POMC: an evolutionary perspective.
Proopiomelanocortin (POMC) is a complex precursor that comprises several peptidic hormones, including melanocyte-stimulating hormones (MSHs), adrenocorticotropic hormone (ACTH), and β-endorphin. POMC belongs to the opioid/orphanin gene family, whose precursors include either opioid (YGGF) or the orphanin/nociceptin core sequences (FGGF). This gene family diversified during early tetraploidizati...
متن کاملIn situ expression of corticotropin-releasing hormone (CRH) and proopiomelanocortin (POMC) genes in human skin.
Systemic stresses induce corticotropin-releasing hormone (CRH) expression in hypothalamus. CRH is released to the pituitary gland, where it stimulates proopiomelanocortin (POMC) production acting via the CRH receptor (CRH-R). CRH and POMC peptides are also detected in sites outside of the central nervous system (CNS), such as the skin. However, it has not been elucidated whether these peptides ...
