Previous studies of the regulation of human ABO gene transcription have focused mainly on the 5' region, including the core promoter and the region proximal to it. However, as the involvement of the 3' flanking region in transcriptional regulation has not yet been examined, we focused on this issue. The 3' region approximately 2.2kb downstream of the ABO gene was PCR-amplified and inserted into a cloning vector, followed by sequence determination and preparation of luciferase reporter vectors. Transient transfections into KATOIII and K562 cells were performed using various reporter plasmids containing the 3' region. The 3' region of the ABO gene, which was characterized by a high degree of sequence repetition, was effectively cloned by a single-copy cloning method. Transfections in KATOIII and K562 cells showed that negative elements were demonstrable within the 3' region. These observations suggest that negative regulatory elements seem to be present in the 3' region of ABO in both epithelial and erythroid lineages. As we had observed a negative region just upstream of the ABO promoter, transcription from ABO could be negatively regulated by repressive regions just upstream of the promoter and downstream of the gene. Further studies of the enhancer will be required for elucidating the molecular basis of ABO gene expression."xsd:string |
