Outline of Final Research Achievements

We have shown that transcription factor Kruppel-like factor 4 (KLF4) modulates podocyte epigenome and attenuates proteinuria(Hayashi, et al. J Clin Invest. 2014). Moreover, we demonstrated that renin-angiotensin system (RAS) blockade reset podocyte epigenome through KLF4 in part(Hayashi, et al. Kidney Int. 2015). These results provide a new concept that RAS blockade can exert therapeutic effects through epigenetic modulation of the kidney gene expression, and suggest a novel therapeutic approach for treatment of proteinuric kidney diseases.
