General description

Neuromedin B (NMB) belongs to the bombesin (BN)-like peptide family in mammals. It is located in the gastrointestinal tract and central nervous system.

Application

Neuromedin B (NMB) has been used as a bombesin (BN)-like peptide:
  • for injection in mice to understand energy expenditure and oxygen consumption and CO2 production
  • to study its effects on the thyrotropin (TSH) and prolactin (PRL) release in vitro
  • to analyze its effects on angiogenesis through the activation of extracellular signal-regulated kinase (ERK) and protein kinase B (Akt) in endothelial cells

Biochem/physiol Actions

Neuromedin B (NMB) exhibits its effects by binding to the cell surface receptors. It facilitates its action on several contractile organs including, the stomach, intestine, esophagus, gall bladder, urinary bladder, and uterus. It also plays a role in food intake, hypothermia, and thermoregulation. NMB is involved in exocrine and endocrine secretion of gastrin, insulin, cholecystokinin, enteroglucagon, and gastric inhibitory peptide. It also acts as an autocrine growth factor in non-small cell lung cancer.

Repeated exposure to stressors was reported to increase the expression of arginine-vasopressin (AVP), especially in corticotropin-releasing hormone (CRH) neurons co-expressing AVP, within the hypothalamus. This may increase the potential for subsequent stressor-elicited enhancement of hypothalamic-pituitary-adrenal (HPA) functioning as these peptides...
