Gene Information

human ... GNRHR(2798)

Application

Cetrorelix, a luteinizing hormone releasing hormone receptor (LHRHR) antagonist, was used to study its safety, mechanism of action, metabolism, and efficacy as a therapeutic agent for the treatment of blood cancers such as multiple myeloma (MM). Cetrorelix is used to evaluate its effects on a wide range of physiological processes and malignancies that involve luteinizing hormone releasing hormone receptor signaling pathways involving processes such as steroidogenesis.

Biochem/physiol Actions

Cetrorelix acetate is a luteinizing hormone releasing hormone receptor antagonist. It causes prepubertal reduction in bone modeling, bone density and bone strength comparable to post-menopausal bone loss.
