MOTIVATION Gene clusters are arrangements of functionally related genes on a chromosome. In bacteria, it is expected that evolutionary pressures would conserve these arrangements due to the functional advantages they provide. Visualization of conserved gene clusters across multiple genomes provides key insights into their evolutionary histories. Therefore,(More)
MOTIVATION It is now well established that microRNAs (miRNAs) play a critical role in regulating gene expression in a sequence-specific manner, and genome-wide efforts are underway to predict known and novel miRNA targets. However, the integrated miRNA-mRNA analysis remains a major computational challenge, requiring powerful informatics systems and(More)
DNA methylation is an epigenetic modification of DNA that adds a methyl group to cytosine. Aberrant DNA methylation in the CpG context is frequently observed in cancer cells and it is known that aberrant DNA methylation silences tumor repressor genes. However, the mechanism of DNA methylation is not well understood. A widely accepted hypothesis is that DNA(More)
A breast cancer subtype classification scheme, PAM50, based on genetic information is widely accepted for clinical applications. On the other hands, experimental cancer biology studies have been successful in revealing the mechanisms of breast cancer and now the hallmarks of cancer have been determined to explain the core mechanisms of tumorigenesis. Thus,(More)
Drought-stress can cause major economic loss and is a serious issue to address in agriculture. Defining the molecular pathways in how a plant responds to drought-stress may prove valuable in developing new drought-resistant plants. In this study, we identified several novel drought-responsive regulatory coding and noncoding transcripts in rice, Oryza sativa(More)
miRNAs are small non-coding RNAs that regulate gene expression by binding to the 3'-UTR of genes. Many recent studies have reported that miRNAs play important biological roles by regulating specific mRNAs or genes. Many sequence-based target prediction algorithms have been developed to predict miRNA targets. However, these methods are not designed for(More)
As more genomic and epigenomic data becomes available, it has become possible to construct biological networks from the omics data. Among the biological networks, understanding gene regulatory mechanisms is a very important research problem that can reveal condition-specific, e.g., disease-specific, gene regulatory mechanisms. In this paper, we review the(More)
This study was designed to investigate at the molecular level how a transgenic version of rice "Nipponbare" obtained a drought-resistant phenotype. Using multi-omics sequencing data, we compared wild-type rice (WT) and a transgenic version (erf71) that had obtained a drought-resistant phenotype by overexpressing OsERF71, a member of the AP2/ERF(More)
