生物活性
Kisspeptin-10, human TFA is a potent vasoconstrictor and inhibitor of angiogenesis, it acts as a tumor metastasis suppressor via its receptor GPR54. Kisspeptin-10/GPR54 signaling induces osteoblast differentiation via NFATc4-mediated BMP2 expression. Kisspeptin-10 (KP-10) and its receptor GPR54 are key components in the regulation of GnRH secretion in humans and other mammals. Kisspeptin-10 protein binds to GPR54. Activation of Kisspeptin-10 suppresses pulmonary human melanoma and Kisspeptin-10 is a metastasis suppressor in breast cancer cells.
In vivo, intravenous infusion of kisspeptin-10 (7.5, 35, and 100 nM) induces a dose-dependent increase in LH secretion. The stimulatory effect of kisspeptin-10 (100 n nM) on LH secretion is blocked by the GnRH antagonist cetrorelix, precluding a singular action on gonadotropes. Kisspeptin-10 inhibits angiogenesis in vivo. Kp-10 inhibits tumor growth in SCID mice xenografted with human prostate cancer cells (PC-3) through inhibiting tumor angiogenesis.
