Outline of Final Research Achievements |
BNP is secreted from the heart and is a cardioprotective peptide, but its precursor proBNP is present in the blood and its biological activity is extremely weak compared to BNP. However, the secretion mechanism of this proBNP was unknown. In this study, we suggested that miR-30, a microRNA abundant in the heart, regulates the gene expression of the O-linked glycosyltransferases, GALNT1 and GALNT2, in a repressive manner, thereby regulating the glycosylation of proBNP by GALNT1 and GANT2, and that miR-30-GALNT pathway is involved in the glycosylation-dependent regulation of the processing and secretion of proBNP.

Academic Significance and Societal Importance of the Research Achievements |
本研究により、低活性のproBNP分泌メカニズムの一端が明らかとなり、これらの分子メカニズムを修飾することで、心不全の新たな診断法や、活性の強いBNPの分泌が促進されるような新たな心不全治療の開発につながる可能性が有る意義のある研究成果が得られたと考える。
