Kisspeptins (including kisspeptin-54 (KP-54), formerly known as metastin) are proteins encoded by the KISS1 gene in humans. Kisspeptins are ligands of the G-protein coupled receptor, GPR54. Kiss1 was originally identified as a human metastasis suppressor gene that has the ability to suppress melanoma and breast cancer metastasis. Kisspeptin-GPR54 signaling has an important role i… Web30 sep. 2024 · We discovered that Kiss1 expression in mouse Leydig cells was induced by LH through the cAMP/PKA pathway. Based on the presence of kisspeptin receptors on spermatids, we inferred that kisspeptin and development-related factors have synergistic effects on spermatogenesis.
Web1 okt. 2024 · Published data on the biological role of kisspeptin in thyroid cancer are sparse. Ringel et al ( Ringel et al., 2002b) found increased expression of kisspeptin receptor in papillary thyroid cancer, as compared to the adjacent normal tissue, suggesting a potential involvement of kisspeptin in modulating the biological behavior of thyroid cancer. WebAbstract. Kisspeptins, derived from the Kiss1 gene play a central role in activation of the hypothalamo-pituitary gonadal (HPG) axis via stimulation of GnRH neurons. Both Kiss1 and Kiss1R (receptor) mRNA levels are found to be low in pre-pubertal rats, but whether an increase in kisspeptin and/or its receptor is the primary component in the ...
WebThe KiSS1-derived peptide receptor (also known as GPR54 or the Kisspeptin receptor) is a Gq-coupled receptor which binds the peptide hormone kisspeptin (metastin). The KiSS1 gene inhibits metastatic activity of melanoma and other tumor cell lines, and clinical evidence supports a role for KiSS1 in inhibition of metastasis in human cancer. WebKISS1R mutants are responsible for the nCHH phenotype in only a small minority of cases and were less prevalent than GnRH Receptor (GNRHR) mutations. What is known …
