Hypermethylation leads to the loss of HOXA5, resulting in JAG1 expression and NOTCH signaling for renal fibrosis
Ontology highlight
ABSTRACT: DNA methylation has been implicated in renal fibrosis. In this study, we demonstrated the induction of DNA methyltransferases and global DNA methylation in fibrotic kidneys, and further proved the beneficial effects of their inhibitor 5-Aza in renal fibrosis. HOXA5 was shown to be down-regulated in fibrotic kidneys through hypermethylation, and this down-regulation led to JAG1 expression and consequent activation of NOTCH signaling for renal fibrogenesis. These findings unveil DNA methylation and related genes, such as HOXA5, as potential therapeutic targets in renal fibrotic disease.
