Abstract

BACKGROUND: Hyperglycaemia is a causative factor in the pathogenesis of diabetic nephropathy, known to induce chemokines in the kidney. Macrophage inflammatory protein-3 alpha (MIP-3 alpha) is a CC chemokine that has been reported to attract memory T lymphocytes. Our previous microarray study showed significant increased level of MIP-3 alpha in high glucose-induced transcriptional profile in renal proximal tubule cells. Transforming growth factor-beta1 (TGF-beta1) is a key regulator in inflammation and fibrosis in diabetes mellitus setting. METHODS: This study aimed to determine the role of TGF beta 1 in high glucose-induced MIP-3 alpha expression. An in vitro model of human proximal tubular..
