Although vascular SMC are known to express the ET(B)-R, its transcriptional regulation has not been studied thus far. Here we demonstrate that the potent inhibitor of nuclear factor kappaB activation, pyrrolidine dithiocarbamate (PDTC; 30-100 microM), induces de novo ET(B)-R expression in rat aortic and mesenteric cultured SMC. Electrophoretic mobility shift analyses revealed that besides inhibition of nuclear factor kappaB, PDTC enhances activator protein-1 (AP-1), CCAAT/enhancer-binding protein (C/EBP), and GATA-2 activity in these cells. Preincubation of PDTC-stimulated cells with appropriate decoy oligodeoxynucleotides confirmed the involvement of these three transcription factors, namely that of AP-1, in ET(B)-R expression. The stimulatory effect of PDTC on ET(B)-R expression was also confirmed functionally by monitoring an enhanced ET-1-induced apoptosis in PDTC-treated cells that was sensitive to the ET(B)-R antagonist, BQ788. Taken together, these findings demonstrate that C/EBP, GATA-2, and in particular AP-1 can control ET(B)-R expression in vascular SMC. They further support the notion that ET(B)-R expression in these cells may play an important role in cardiovascular complications, such as restenosis following angioplasty that in the early phase is characterized by prominent SMC apoptosis."; prov:wasQuotedFrom pubmed:11093771 . sub:_5 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:11093771; prov:wasDerivedFrom beldoc:, sub:_4 . } sub:pubinfo { this: dct:created "2014-07-03T14:31:38.235+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
