In this study, using looping chromatin immunoprecipitation and chromatin conformation capture assays, we demonstrated that interactions between Runx1 and positive elongation factor b (P-TEFb) appose the silencer and enhancer in CD4-negative thymoma cells and double-negative immature thymocytes. This chromatin loop decoys P-TEFb away from the promoter, thus preventing RNA polymerase II from elongating on the CD4 gene. In the absence of Runx1 on the silencer, P-TEFb interacts with the transcription complex, forming a different chromatin loop between the enhancer and the promoter, which leads to the expression of the CD4 gene in CD4-positive hybridoma cells and double-positive thymocytes. Moreover, the knockdown of CycT1 from P-TEFb abolishes both of these chromatin loops. Finally, the selective removal and restoration of Runx1 causes rapid interchanges between these chromatin loops, which reveals the plasticity of this regulatory circuit. Thus, differential looping and decoying of P-TEFb away from the promoter mediate active repression of the CD4 gene during thymocyte development."xsd:string |
