Genome-wide analysis revealed that DZNep reduces tubulointerstitial fibrosis via down-regulation of pro-fibrotic genes.

ABSTRACT: Tubulointerstitial fibrosis has been recently reported to be caused by the collapse of the epigenetic regulation of kidney diseases. We examined whether pharmacological inhibition of histone modification is effective against renal fibrosis. DZNep (3-deazaneplanocin A) was originally developed as an anti-cancer drug to inhibit the repressive histone mark, H3K27me3. We used a model of chronic tubulointerstitial fibrosis induced by unilateral ischaemia/reperfusion and administered DZNep intravenously to the mice for 8 weeks. We found DZNep contributes to the reduction of tubulointerstitial fibrosis. We selected only tubular cells from in vivo samples using laser-capture microdissection because epigenetic regulation is specific to the cell types, and we focused on the changes in the tubular ce
