Since its discovery, this form of LHRH (LHRH-I) has been shown to be one of many structural variants with a variety of roles in both the brain and peripheral tissues. Enormous interest has been focused on LHRH-I, LHRH-II, and their cognate receptors as targets for designing therapies to treat cancers of the reproductive system. LHRH-I is processed by a zinc metalloendopeptidase EC 3.4.24.15 (EP24.15) that cleaves the hormone at the Tyr(5)-Gly(6) bond. We have previously reported that the autoregulation of LHRH gene expression can also be mediated by its processed peptide, LHRH-(1-5). Given its importance in the brain, we have investigated the role of the specific processed peptide of LHRH-I, LHRH-(1-5), within Ishikawa cells, a human endometrial cell line. Using real-time polymerase chain reaction, we observed that LHRH-(1-5) upregulates LHRH-II mRNA expression in Ishikawa cells but does not exert any influence on LHRH-I mRNA levels. This is in contrast to the effects of LHRH-I, which affects the expression of LHRH-I mRNA. Our findings support a potential role for LHRH-(1-5) as a processed metabolite in the endometrium. Further investigations are needed to determine the role of this processed metabolite and to identify specific pathways involved in LHRH-(1-5) signaling. ------>tmu_sno=None ------>sno=20794 ------>authors2=Marcelin K ------>authors3=Hsu MI ------>authors4=Chang CM ------>authors5=Hoffman G ------>authors6=Roberts JL ------>authors6_c=Roberts JL ------>authors=Dong KW ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=Marcelin K ------>publish_area=0 ------>updateTitle=Regulation of type II luteinizing hormone-releasing hormone (LHRH-II) gene expression by the processed peptide of LHRH-I, LHRH-(1-5) in endometrial cells. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=5 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=1998 ------>submit_flag=None ------>publish_month=9 |
