To study the luteinizing hormone-releasing hormone (LH-RH; luliberin) receptors in the rat anterior pituitary gland and ovary, 125I-labeled [D-Ser(TBU)6des-Gly-NH2(10)]LH-RH ethylamide was used as a labeled ligand. The binding characteristics were assessed by Scatchard analysis of labeled ligand binding and by potency displacement with unlabeled peptides. Similar Kd values, ranging from 0.1 to ...

Recent evidence suggests that neurokinin B (NKB), a member of the neurokinin (tachykinin) peptide family, plays a pivotal role in gonadotropin-releasing hormone (GnRH) pulse generation. Three types of neurokinin receptors (NKRs), NK1R, NK2R and NK3R, are found in the brain. Although NKB preferentially binds to NK3R, other NKRs are possibly also involved in NKB action. The present study examined...

Androgen deprivation therapy (ADT) is one of the main treatments for patients with locally advanced and metastatic prostate cancer. ADT decreases level testosterone. Despite development new effective drugs in recent years, luteinizing gonadotropin-releasing hormone agonists are frequently administered as ADT. One most commonly used first-line triptorelin (Diferelin®). In Russia, usually receive...
