Research Abstract

We performed genome-wide analysis of novel-sized (50-100nt) small RNAs that is originally discovered in the gene loci producing endogenous antisense RNA, based on the custom-made microarrays. The expression validation was analyzed by Northern hybridization. We developed a structural screening method by the in NMR tube transcription for the structural analysis of small RNA. We also performed a trial expression analysis of small RNAs using the next generation sequencers and structural clustering of the RNA sequences.
