Use of Lamprey LH-RH I

Lamprey LH-RH I is a gonadotropin-releasing hormone, elevates plasma steroid levels and stimulates ovulation in the lamprey without biological activity in other animal models[1].

In Vitro	Lamprey LH-RH I has a primary mechanism of transport to the pituitary is simple diffusion from neuronal terminals in the neurohypophysis to the adenohypophysis. An additional route is via secretion into the third ventricle and transport by tanycytes to the adenohypophysis[2].
In Vivo	Lamprey LH-RH I (5-200 μg/kg; i.p.; single dose or twice) elevates plasma steroid levels and stimulates lamprey ovulation[1]. Animal Model: Female sea-run sea lampreys[1] Dosage: 5 μg/kg, 50 μg/kg, 100 μg/kg, 200 μg/kg; dissolved in 0.6% NaCl in distilled water Administration: Intraperitoneal injection; single dose or twice; observed for 30 days Result: Significantly increased estradiol in a dose-related manner. Resulted 80% of the lampreys ovulation at 200 or 100 μg/kg compared in a doserelated manner.
