MicorRNA (miRNA) is a small noncoding RNA and a miRNA is the gene. The identification of the human miRNA gene and its application have been performed and then it has been proceeding to explain about functioning of miRNAs in miRNA-messenger RNA targeting, profiling of miRNAs for diseases, transduction of the miRNA gene expression, production of human-induced pluripotent stem (iPS) cells by miRNA, embryonic stem (ES) cells and cancer development upon miRNA. The RNA information supplied by the miRNA gene, and the RNA gene information could expand to intracellular, intercellular, intraorgan, interorgan, intraspecies and interspecies. Therefore, the implantation of ES and iPS cells from donors would deliver xenotropic miRNAs to the acceptor. The therapeutic efficacy for treatment of iPS-derived cell implantation is the most important for clinical development of the stem cell researches but the xenotropic miRNA gene assessment with iPS-derived cells should substantially be completed for a safe and an exact application of the stem cell researches. 展开更多

Comparative analyses of genome structure and sequence of closely related species have yielded insights into the evolution and function of plant genomes. A total of 103,844 BAC end sequences delegated -73.8 Mb of O. officinalis that belongs to the CC genome type of the rice genus Oryza were obtained and compared with the genome sequences office cultivar, O. sativa ssp.japonica cv. Nipponbare. We found that more than 45% of O. officinalis genome consists of repeat sequences, which is higher than that of Nipponbare cultivar. To further investigate the evolutionary divergence of AA and CC genomes, two BAC-contigs of O. officinalis were compared with the collinear genomic regions of Nipponbare. Of 57 genes predicted in the AA genome orthologous regions, 39 had orthologs in the regions of the CC genome. Alignment of the orthologous regions indicated that the CC genome has undergone expansion in both genic and intergenic regions through primarily retroelement insertion. Particularly, the density of RNA transposable elements was 17.95% and 1.78% in O. officinalis and O. sativa, respectively. This explains why the orthologous region is about 100 kb longer in the CC genome in comparison to the AA genome. 展开更多
