    Although histone acetylation, an epigenetic modification, has been reported to be related to the progression of various diseases, its involvement in nephrosclerosis is unclear.. Dahl salt-sensitive rats were used as a model of nephrosclerosis in this study. The rats were divided into three groups: (i) normal-salt diet group, (ii) high-salt diet group (HS), and (iii) HS administered daily with curcumin, a histone acetyltransferase inhibitor (HS+C). At 6 weeks after the treatment, the kidneys were dissected. Morphologic changes were assessed by Masson's trichrome staining. The number of macrophages, fibroblasts and the cells expressing acetylated histone H3 at Lys 9 (H3K9) were assessed by immunohistochemistry.. Although both HS and HS+C rats revealed a marked increase in systolic blood pressure, serum creatinine was increased only in HS rats at 6 weeks. In the HS rats, nephrosclerosis was induced, accompanying a significant accumulation of macrophages and fibroblasts. The inflammation and fibrosis was markedly suppressed in the HS+C group. The level of histone acetylation at Lys 9 was enhanced in the HS rats, whereas curcumin administration suppressed the histone acetylation. Moreover, in the HS rats, interleukin-6 gene expression was associated with acetylated H3K9, as revealed by chromatin immunoprecipitation assay.. Our results suggested that curcumin ameliorates nephrosclerosis via suppression of histone acetylation, independently of hypertension.
