In these studies we have examined the ability of classical GnRH I and the second form of this hormone (GnRH II) to regulate MMP-2, MMP-9, and TIMP-1 mRNA and protein levels in extravillous cytotrophoblasts propagated from explants of first trimester chorionic villi. GnRH I and GnRH II were found to increase MMP-2 and MMP-9 mRNA and protein levels in these primary cell cultures in a dose- and time-dependent manner using quantitative competitive-PCR and ELISA. In contrast, these two hormones decreased trophoblastic TIMP-1 mRNA and protein levels. Cetrorelix, a GnRH receptor antagonist, inhibited the regulatory effects of GnRH I, but not GnRH II, on MMP-2, MMP-9, and TIMP-1 expression in these cells. Collectively, these observations suggest that GnRH I and GnRH II differentially regulate MMP-2, MMP-9, and TIMP-1 expression in human trophoblasts, possibly via distinct receptor-mediated intracellular signaling pathways. ------>tmu_sno=None ------>sno=9465 ------>authors2=Zhu H ------>authors3=MacCalman CD ------>authors4=Leung PC ------>authors5= ------>authors6= ------>authors6_c=None ------>authors=Chou CS ------>delete_flag=0 ------>SCI_JNo=None ------>authors2_c=None ------>publish_area=None ------>updateTitle=Regulatory effects of gonadotropin-releasing hormone (GnRH) I and GnRH II on the levels of matrix metalloproteinase (MMP)-2, MMP-9, and tissue inhibitor of metalloproteinases-1 in primary cultures of human extravillous cytotrophoblasts. ------>language=2 ------>check_flag=None ------>submit_date=None ------>country=None ------>no=10 ------>patent_SDate=None ------>update_bywho=None ------>publish_year=2003 ------>submit_flag=None ------>publish_month=None |
