GHRF, rat

GHRF, rat (Growth Hormone-Releasing Factor, rat) is a high-purity synthetic peptide corresponding to the 44-amino acid sequence of rat growth hormone-releasing hormone (GHRH). This bioactive peptide functions as a potent and specific agonist for GHRH receptors, stimulating growth hormone secretion from pituitary somatotrophs. With HPLC-verified purity and comprehensive analytical documentation, it provides researchers with a reliable tool for studying growth axis regulation, endocrine physiology, and metabolic processes. Ideal for both in vitro and in vivo applications in rat models, this peptide ensures consistent performance in growth hormone research, drug discovery, and endocrine disorder studies.

1.MECHANISM OF ACTION

GHRF, rat binds with high affinity to GHRH receptors on pituitary somatotroph cells, activating G-protein coupled signaling pathways. This binding stimulates adenylate cyclase activity, increasing intracellular cAMP levels and activating protein kinase A (PKA). The downstream effects include phosphorylation of transcription factors (such as CREB), enhanced growth hormone gene expression, and stimulation of growth hormone synthesis and secretion. The peptide exhibits species specificity for rat GHRH receptors, making it particularly valuable for rat-based research models of growth and endocrine function.
