HIGH INCIDENCE OF RECEPTORS FOR LUTEINIZING HORMONE-RELEASING HORMONE (LHRH) AND LHRH RECEPTOR GENE EXPRESSION IN HUMAN PROSTATE CANCERS

Journal of Urology, 2000
Agonistic analogs of luteinizing hormone-releasing hormone (LHRH) are widely used for therapy of advanced prostate cancer based upon their ability to suppress testosterone secretion in patients. Various studies also indicate that LHRH analogs might have direct inhibitory effects on prostate tumors mediated by specific LHRH receptors.

Enhanced Anti-Tumoral Activity of Methotrexate-Human Serum Albumin Conjugated Nanoparticles by Targeting with Luteinizing Hormone-Releasing Hormone (LHRH) Peptide [PDF]

International Journal of Molecular Sciences, 2011
Active targeting could increase the efficacy of anticancer drugs. Methotrexate-human serum albumin (MTX-HSA) conjugates, functionalized by luteinizing hormone-releasing hormone (LHRH) as targeting moieties, with the aim of specifically targeting the ...

Characterization and autoradiographic localization of LHRH receptors in the rat brain

Synapse, 1987
AbstractLuteinizing hormone‐releasing hormone (LHRH) is distributed in several extrahypothalamic areas, suggesting that it might act as a neurotransmitter or neuromodulator in the central nervous system. This study was undertaken to characterize and localize LHRH receptors in the rat brain by using slide‐mounted frozen sections.

LHRH Receptor Targeted Therapy for Breast Cancer

2008
Breast cancer remains the most common cancer among women, with an estimated 212,920 new cases and 40,970 deaths in the United States in 2006. The present work extends the studies of nanoparticles targeted to the luteinizing hormone-releasing hormone (LHRH) receptor which is overexpressed in breast, ovarian, endometrial and prostate cancer cells.

Modulation of hippocampal LHRH receptors by sex steroids in the rat

Peptides, 1988
The modulation of brain LHRH receptors by sex steroids was assessed in the female rat hippocampus using in vitro autoradiography and iodinated [D-Ser (TBU)6, des-Gly-NH2(10)]LHRH ethylamide as the radioligand. As evaluated by optical densitometry, the density of hippocampal LHRH receptors was increased by castration.

LHRH receptor expression in sarcomas of bone and soft tissue

Hormone Molecular Biology and Clinical Investigation, 2016
Abstract Aim: Luteinizing hormone releasing hormone (LHRH) is a neurohormone, secreted by the hypothalamus, which regulates the secretion of gonadotropins, luteinizing hormone (LH) and follicle stimulating hormone (FSH) from the pituitary.

Receptor-mediated internalization of LHRH antagonists by pituitary cells

Molecular and Cellular Endocrinology, 1983
A fluorescently labeled antagonist of luteinizing hormone releasing hormone (LHRH), D-pGlu-D-Phe-D-Trp-Ser-Tyr-D-Lys6-(tetramethylrhodamine)-Leu-Arg-Pro-Gly-NH2, was prepared. This peptide retained high-affinity binding to the LHRH receptor of pituitary plasma membrane preparations.

Effects of an LHRH agonist and gonadotropins on testicular prolactin receptors

Peptides, 1982
Effects of administration of the LHRH agonist D-Leu6-LHRH ethylamide (LHRH-A), gonadotropin (PMS), and their interaction on testicular prolactin (PRL) receptor levels were investigated in rats. LHRH-A (2 micrograms/100 g body wt.) or saline was injected SC daily, and PMS (5 IU) injected every other day.

Opposite Changes of Pituitary and Ovarian Receptors for LHRH in Ageing Rats: Further Evidence for a Direct Neural Control of Ovarian LHRH Receptor Activity

Neuroendocrinology, 2008
Hypophyseal and ovarian receptors for the neurohormone LHRH (LHRH-R) have been measured in young (3–4 months), middle-aged (8–11 months), constant estrous (CE, 10–14 months) and pseudopregnant (PR, 16–18 months) rats in order to study whether changes in hypothalamic and/or peripheral LHRH-like peptide production might precede and/or accompany the onset

Abstract 5476: LHRH receptor targeting as mechanism of anti-tumor activity for cytotoxic conjugates of Disorazol Z with the LHRH receptor agonistic peptide D-Lys6-LHRH.

Cancer Research, 2013
Abstract Background For drug-targeting aimed at the treatment of LHRH receptor overexpressing cancers the LHRH receptor agonistic peptide D-Lys6-LHRH has been conjugated to the novel highly cytotoxic natural compound Disorazol Z.
