| Research Abstract |
In order to explore functional non-coding sequences hidden in the higher eukaryotic genomes, we conducted bioinformatic analyses of whole genomic sequences of human and other major model animals. First, we conducted comparative genomics analyses of human and other mammalian species, and created a new database of genomic sequence alignments named as G-compass (http://www.jbirc.aist.go.jp/g-compass/). While creating the genomic alignments, we discovered 82 human genomic regions that were completely conserved between human and mouse. Some of these conserved regions overlapped with known genes, but others were suggested to contain unidentified functional elements in the human genome. These results were reported in a paper by Fujii et al. (2005). Furthermore, we compared whole genomic sequences of human, chimpanzee, mouse and rat, and found that only 16.4% of the human genome is conserved in all these four species. This result was reported in a paper by Sakate et al. (2006). Next, we explored functional non-coding elements in the human genome. By sequence analyses of human genome and human transcripts, we predicted many new candidates of human microRNAs and their potential target (regulated) genes. A part of these results was applied for patents. In conclusion, we developed methods for identifying functional non-coding elements in the genomes, and succeeded in identifying some of them.
