CTCF was found to interact with XL9 by in vivo (chromatin immunoprecipitation [ChIP]) and in vitro (electrophoretic mobility shift assay) assays (14) (15). To test the hypothesis that CTCF plays a role in the regulation of the flanking MHC genes HLA-DRB1 and HLA-DQA1, siRNAs were used to knockdown the expression of CTCF.Assessment of HLA-DRB1 and HLA-DQA1 mRNA expression during the knockdown time course assays showed a marked reduction in steady-state mRNA levels of both HLA-DRB1 and HLA-DQA1 when siRNAs to CTCF but not GFP were used (Fig. 1 C).
