MiRaGE method + miRNA expression successfully pick up biologically important miRNAs. Further (wet) experiments which supress miRNA expression with tiny LNA is now planed.

If it is successful, our method can find miRNAs which control tumor formation.

miRNA is short non­coding RNA which regulate many biological processes ranging from cancer formation to differentiation.We have proposed a new method, MiRaGE, MiRNA Ranking by Gene Expression, which assists to discriminate which miRNA really regulate target genes.Since there are some technical method which suppress miRNA machinery, it can also be a drug candidates related to several biological processes.
