Research Abstract

We analyzed the characteristic gene regulation mechanism in terminally differentiating neuronal cells by identifying the genomic region targeted by DNA topoisomerase IIbeta (topo IIb) and its partner protein SP120/hnRNP U through massive sequencing on new generation sequencers. Results are summarized as follows: 1) Topo IIb regulates the transcription of groups of genes in both directions (up- and down-regulation). 2) Genes controlled by topo IIb are positioned non-randomly on the genome. 3) Analysis of the topo IIb action sites (toposites) suggested that the toposite enriched in intergenic regions (termed Ts3) has an important role in the gene expression of terminal differentiation. 4) The SP120-binding sites overlapping with Ts3 toposites appear to be the target of topo IIb-SP120 complex, which was also demonstrated by cytological methods as nuclear colocalization spots. 5) Ts3 toposites represent the topo IIb-mediated distant interaction sites involved.
