BackgroundThese studies were designed to investigate chronologic changes of transforming growth factor-β1 (TGF-β1) expression during the evolution of glomerulosclerosis in rats after partial nephrectomy.MethodsThe time course of TGF-β1 expression and its localization at the renal cortex was examined immunohistochemically in thirty-six 5/6 nephrectomized (Nx) and 30 sham-operated Wistar rats serially at 3 days and at 1,2,4,8 and 12 weeks after surgery. The extent of glomerulosclerosis was assessed by using the sclerosis index (index range, 0 to 4). Monocyte/macrophage infiltration and type IV collagen were immunohistochemically identified using the monoclonal antibody ED1 and monoclonal anti-type IV collagen antibody, respectively.ResultsAt 12 weeks, the sclerosis index was 1.64±0.20 and 0.06±0.01 (P<0.0001, analysis of variance) in 5/6 nephrectomized and sham-operated rats, respectively. In the nephrectomized rats, the area of positive-TGF-β1 staining increased time-dependently, concomitant with positive results for ED1 and type IV collagen stainings. There was a strong topologic relationship among TGF-β1, ED1, and type IV collagen expression. Northern blot analysis of TGF-β1 messenger ribonucleic acid (mRNA) showed time-dependently augmented expression in nephrectomized, but not in shamoperated, rats (0.8-, 2.2-, 1.6,- and 3.4-fold at 1, 4, 8 and 12 weeks, respectively).ConclusionTGF-β1 plays a pivotal role in the progression of glomerulosclerosis in nephrectomized rats, in association with infiltration of monocytes/macrophages.
