Class I HDACs specifically regulate E-cadherin expression in human renal epithelial cells.

ABSTRACT: Epithelial-mesenchymal transition (EMT) and renal fibrosis are closely involved in chronic kidney disease. Inhibition of histone deacetylase (HDAC) has an anti-fibrotic effect in various diseases. However, the pathophysiological role of isoform-specific HDACs or class-selective HDACs in renal fibrosis remains unknown. Here, we investigated EMT markers and extracellular matrix (ECM) proteins in a human proximal tubular cell line (HK-2) by using HDAC inhibitors or by knockdown of class I HDACs (HDAC1, 2, 3 and 8). Trichostatin A (TSA), MS275, PCI34051 and LMK235 inhibited ECM proteins such as collagen type I or fibronectin in transforming growth factor β1 (TGF-β1)-induced HK2 cells. However, restoration of TGF-β1-induced E-cadherin down-regulation was only seen in HK-2 cells treated with TSA
