Luteinizing hormone-releasing hormone antagonists.
BACKGROUND Luteinizing hormone-releasing hormone (LH-RH) plays a central role in the vertebrate reproduction by regulating gonadal activity. Based on its binding to pituitary LH-RH receptors, as well as to LH-RH receptors expressed on cancer cells, LH-RH agonists and antagonists have been developed for different therapeutic applications. OBJECTIVE/METHOD Here we give an overview of the most r...
متن کاملQuick release of FSH stimulated by repeated applications of synthetic luteinizing hormone-releasing hormone (LH-RH) in immature male rats.
Serum FSH and LH levels were estimated by radioimmunoassay following single subcutaneous administration, and repeated subcutaneous administration at various intervals in immature male rats. Single injection of LH-RH induced slight increase in FSH levels in comparison with considerable increase in LH. By two successive injections, the release of FSH was markedly stimulated when the time interval...
متن کاملEffect of manganese on luteinizing hormone-releasing hormone secretion in adult male rats.
Recently studies have demonstrated that low doses of (Mn(+2)) in the form of manganese chloride can stimulate specific puberty-related hormones and advance signs of pubertal development in immature female and male rats. In the present study, we used an in vitro system to evaluate the ability of 0, 50, 250, and 500 microM doses of Mn(+2) to stimulate luteinizing hormone-releasing hormone (LHRH) ...
متن کاملThe response to luteinizing hormone-releasing hormone in normal men.
Synthetic luteinizing hormone-releasing hormone (LH-RH) was given in doses of 11-100 Vg to normal men. Doses of 50 and 100 t±g caused a twoto ten-fold rise in serum LH in all subjects, but in only 40% was the serum follicle-stimulating hormone (FSH) elevated. A significantly higher LH response to LHRH was seen in subjects in whom a rise in serum FSH could be detected. Although there was a wide ...
متن کاملA luteinizing hormone-releasing hormone agonist decreases biological activity and modifies chromatographic behavior of luteinizing hormone in man.
The effect of the luteinizing hormone-releasing hormone (LHRH) agonist, [D-Trp6,Pro9-NEth]LHRH (LHRHA), on luteinizing hormone (LH) bioactivity was assessed with a rat interstitial cell assay in four men during a 14-d treatment period. Biologic/immunologic (B/I) ratios were unchanged initially with treatment but by day 12 had fallen to levels lower than basal values. Frequent sampling on day 12...
