Luteinizing hormone-releasing hormone neurons express Fos protein during the proestrous surge of luteinizing hormone.
The ability of luteinizing hormone-releasing hormone (LHRH) neurons to express the oncogene c-fos was examined during the estrous cycle in rats. The immunocytochemical localization of the c-fos-encoded antigen, Fos, was coupled with the immunocytochemical localization of LHRH. LHRH neurons showed no Fos immunoreactivity during diestrus-1, diestrus-2, estrus, or the morning of proestrus. However...
متن کاملLuteinizing 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 کاملGABA inhibits migration of luteinizing hormone-releasing hormone neurons in embryonic olfactory explants.
During development, a subpopulation of olfactory neurons transiently expresses GABA. The spatiotemporal pattern of GABAergic expression coincides with migration of luteinizing hormone-releasing hormone (LHRH) neurons from the olfactory pit to the CNS. In this investigation, we evaluated the role of GABAergic input on LHRH neuronal migration using olfactory explants, previously shown to exhibit ...
متن کاملHuman malignant melanomas express receptors for luteinizing hormone releasing hormone allowing targeted therapy with cytotoxic luteinizing hormone releasing hormone analogue.
Cytotoxic analogue of luteinizing hormone releasing hormone (LHRH), AN-207, binds with high affinity to LHRH receptors and can be targeted to tumors expressing these receptors. We investigated the expression of LHRH receptors in surgical specimens of human malignant melanoma and evaluated the effects of AN-207 in models of human melanoma. Human melanoma specimens derived from primary tumors or ...
متن کاملPolysialic acid facilitates migration of luteinizing hormone-releasing hormone neurons on vomeronasal axons.
Luteinizing hormone-releasing hormone (LHRH) neurons migrate from the olfactory placode to the forebrain in association with vomeronasal nerves (VNN) that express the polysialic acid-rich form of the neural cell adhesion molecule (PSA-NCAM). Two approaches were used to investigate the role of PSA-NCAM: injection of mouse embryos with endoneuraminidase N, followed by the analysis of LHRH cell po...
