OBJECTIVE The hypothalamus plays a crucial role in the regulation of feeding behavior. The anorexigenic neuropeptide alpha-melanocyte-stimulating hormone (α-MSH) and the orexigenic neuropeptide agouti-related protein (AgRP) are among the major peptides produced in the hypothalamus. This study investigated the plasma concentrations of α-MSH and AgRP in underweight and obese children and their he...
OBJECTIVE Central melanocortin pathways are well-established regulators of energy balance. However, scant data exist about the role of systemic melanocortin peptides. We set out to determine if peripheral α-melanocyte stimulating hormone (α-MSH) plays a role in glucose homeostasis and tested the hypothesis that the pituitary is able to sense a physiological increase in circulating glucose and r...
Maxillary sinus hypoplasia (MSH) is an uncommon abnormality of paranasal sinuses noted in clinical practice. Computed tomography (CT) scan helps in diagnosing the anomaly along with any anatomical variation that may be associated with it. MSH is usually associated with other anomalies like uncinate process hypoplasia. Three types of MSH have been described. Type 1 MSH shows mild maxillary sinus...
The present communication is concerned with two substances possessing melanocyte-stimulating hormone (MSH) activity, ar-MSH and /3-MSH, found in hog pituitary gland. The main component, o(-MSH, was isolated by a four-step process consisting of solvent extraction and fractional precipitation, oxycellulose adsorption, counter-current distribution, and paper electrophoresis. a-MSH has been found t...
Melanophore-stimulating hormone (MSH) release from the pars intermedia of the pituitary gland is probably regulated by multiple factors of hypothalamic origin. We have examined a number of potential regulatory factors for their effects on MSH release from the amphibian Xenopus laevis. Serotonin and acetylcholine have no effect on MSH release. Both adrenaline and noradrenaline inhibit release of...
Mycothiol (MSH) is the major low-molecular-mass thiol in mycobacteria and is associated with the protection of Mycobacterium tuberculosis from toxic oxidants and antibiotics. The biosynthesis of MSH is a multistep process, with the enzymatic reaction designated MshC being the ligase step in MSH production. A targeted disruption of the native mshC gene in M. tuberculosis Erdman produced no viabl...
Mismatch repair genes are important in maintaining the fidelity of DNA replication. To determine the function of the Caenorhabditis elegans homologue of the MSH2 mismatch repair gene (msh-2), we isolated a strain of C. elegans with an insertion of the transposable element Tc1 within msh-2. Early-passage msh-2 mutants were similar to wild-type worms with regard to lifespan and meiotic chromosome...
Melanocortin-1 (MC1) receptor is an attractive melanoma-specific target over-expressed on the surface of melanoma cells. Alpha-melanocyte stimulating hormone (alpha-MSH) peptide analogues can specifically bind MC1 receptors with nanomolar binding affinities, making alpha-MSH peptide analogues very promising candidates for developing effective melanoma-specific imaging probes. This review highli...
Abstract Several approaches have been used to reduce the accumulation of heavy metals in aqueous solutions, including adsorption surface agricultural waste. Batch studies performed this study explore Fe 2+ , Mn on olive pomace (OP), and moringa seed husk (MSH). Fourier transform infrared scanning electron microscopy also characterized prepared adsorbent. were performed, effects adsorbent chemic...
Two melanotropic peptides, melanin concentration hormone (MCH) and alpha-melanocyte stimulating hormone (alpha-MSH), exert opposing actions on melanosome (melanin granule) movements within teleost pigment cells, melanocytes (melanophores). MCH stimulates melanosome aggregation to the cell center whereas alpha-MSH stimulates pigment organelle dispersion out into the dendritic processes of the me...
