Peptide/protein hormones could be stored as non-toxic amyloid-like structures in pituitary secretory granules. ACTH and β-endorphin are two of the important peptide hormones that get co-stored in the pituitary secretory granules. Here, we study molecular interactions between ACTH and β-endorphin and their colocalization in the form of amyloid aggregates. Although ACTH is known to be a part of A...

Obesity is the main cause of premature death in the UK. Worldwide its prevalence is accelerating. It has been hypothesized that a gut nutriment sensor signals to appetite centres in the brain to reduce food intake after meals. Gut hormones have been identified as an important mechanism for this. Ghrelin stimulates, and glucagon like peptide-1, oxyntomodulin, peptide YY (PYY), cholecystokinin an...

Obesity is one of the major challenges to human health worldwide; however, there are currently no effective pharmacological interventions for obesity. Recent studies have improved our understanding of energy homeostasis by identifying sophisticated neurohumoral networks which convey signals between the brain and gut in order to control food intake. The hypothalamus is a key region which possess...

The structures of three polypeptide hormones (glucagon, a 25-residue analogue of adrenocorticotropin, and parathyroid hormone) which contain enough residues to permit organization have been evaluated in aqueous solution by fluorescence and circular dichroism. The effects of pH, temperature, and guanidine on both tyrosyl and tryptophanyl emission have been measured. None of the fluorescence para...

Obesity is an escalating health problem in developing countries. One to ten children worldwide are overweight a report showed by the International Task Force. Ghrelin, orexigenic peptide, has 28 amino acids, it considered greatest remarkable promotion last two decades for understanding physiological changes of action regu­lating food intake and hunger. Obestatin 23-amino acid peptide nearly con...

The regulation of appetite is regulated by complex mechanism involving brain-gut axis and hormonal and non-hormonal factors acting through the activity of satiety and hunger centers located in the hypothalamus [Wren & Bloom, 2007]. Among hormones controlling appetite are gastrointestinal hormones such as cholecystokinin, PYY, pancreatic polypeptide, glucagon-like peptide 1, oxyntomedulin, the e...

BACKGROUND Natriuretic peptide concentrations in adults require age- and sex-specific reference intervals for optimal interpretation. Females have higher natriuretic peptide concentrations, and hypotheses suggest that estrogen may be responsible. This study sought to determine the influence of hormone modulation on N-terminal probrain natriuretic peptide (NT-proBNP) by using a pediatric cohort....
