Gonadorelin diacetate BiologicalActivity

Description	Luteinizing Hormone Releasing Hormone (LH-RH), human is hypothalamic neuropeptide which plays a key role in the control of reproductive functions.

In Vitro	Luteinizing Hormone Releasing Hormone (LH-RH), also called gonadotropin-releasing hormone (GnRH), is the primary link between the brain, the pituitary and gonadal function, and has a key role in vertebrate reproduction. The endocrine actions of Luteinizing Hormone Releasing Hormone (LH-RH) and its analogs are mediated by high-affinity membrane receptors for LHRH on pituitary gonadotrophs[1]. LHRH is expressed,together with its receptors,in hormonerelated tumors such as prostate cancer,to act as a local autocrine/paracrine growth inhibitory factor. In prostate cancer cells,the LHRH receptor is coupled to the Gi-cAMP pathway to inhibit cell proliferation[3].
In Vivo	Luteinizing Hormone Releasing Hormone treatment advances the timing of vaginal opening by 5 days, which is used as an initial indicator for the time of puberty[2].
Animal Admin	Rats[2] Immature female Sprague-Dawley rats receive either 50 ng Luteinizing Hormone Releasing Hormone (LH-RH)/kg BW or 20 mg NMA/kg BW in a 10% dextrose, 0.9% NaCl solution, while controls receive only vehicle. After completion of the treatment, rats are examined daily for vaginal opening[2].
