In collaboration with the Department of Surgery, Osaka University (Profs. Masaki Mori and Yuichiro Doki), Konno et al. found a unique role of the embryonic miR-369- HNRNPA2B1 axis in controlling metabolic enzyme function. The data suggest a novel pathway linking epigenetic, transcriptional, and metabolic control in cell reprogramming, and may be useful for the novel diagnostic approaches and therapies in regenerative medicine and cancer research.
