| Research Abstract |
Human intestinal CYP3A4 and ABCB1 mRNA expression levels showed large inter-individual differences and a significant association between them. The CpG island located in the region between CYP3A4and ABCB1 genes locus were analyzed by bisulfite sequencing method. Some CG sites (No. 14-18) were partially demethylated in human intestinal samples. Since these regions include CTCF binding regions, demethylation in the CG sites (No. 14-18) are suggested to be important for cohesion mediating transcriptional insulationin CYP3A4 and ABCB1 gene locus.
