Change in post-translational modifications of histone H3, heat-shock protein-27 and MAP kinase p38 expression by curcumin in streptozotocin-induced type I diabetic nephropathy

Abstract

Curcumin has been used to treat cancer, diabetes and other pathologies. However, little is known regarding its role in altering post-translational modifications of histone H3. A recent report suggests that acute hyperglycaemia induces a global down-regulation of gene expression in human tissues and epigenetic regulation of gene expression could be a novel mechanism underlying the pathological processes of hyperglycaemia. The present study was undertaken to examine changes in histone modification by curcumin treatment which prevents development of type I diabetic nephropathy.
