Protein levels from rat kidney cortex homogenates and from cell lysates were quantitated using immunoblotting as described by us previously73 (link)74 (link)75 (link)76 (link)77 (link)78 (link)79 (link)80 (link). The antibodies against HDACs (Cell signalling technology, MA USA), E-cadherin, Fibronectin, Collagen, RAGE (Santa Cruz Biotechnology, USA), TGF-beta, Histone H3, acetyl Histone H3 (Abcam MA USA) and anti-acetyl Histone H4 (Millipore) and, anti-β-actin (Cell signalling technology, MA USA) were used and signals were detected using a chemi-luminiscence-based detection system (Amersham). The levels of protein expression were quatitated using the Quantity one (BioRad) software.
