Introduction of CXCR4 cDNA into IkappaB-expressing cells restored SDF-1alpha-mediated migration. Electrophoretic mobility shift assays and transient transfection assays revealed that the NF-kappaB subunits p65 and p50 bind directly to sequences within the -66 to +7 region of the CXCR4 promoter and activate transcription." ; prov:wasQuotedFrompubmed:12690099 . sub:_5rdfs:label "Selventa" . sub:assertionprov:hadPrimarySourcepubmed:12690099 ; prov:wasDerivedFrombeldoc: , sub:_4 . }
