Objective:To study the relationship between the expression of TGF-β 1 and the formation and progression of experimental uric acid granulomas in rats.Methods:The formation and progression of granulomas in 30 cases of uric acid nephropathy
the expressions of protein and mRNA of TGF-β 1
moreover PCNA
α-SMA and collagen Ⅲ were investigated with ABC immunohistochemical staining and in situ hybridization techniques.Results:The mononuclear cells in granulomas and the injured renal tubular cells expressed TGF-β 1mRNA
and synthesized protein of TGF-β 1 and PCNA.In the late stage
the degree of the expression of TGF β 1 and the deposition of collagen Ⅲ were in coincidence in granulomas.Conclusion:TGF-β 1 promotes the forming of granulomas by stimulating the proliferation in situ of mononuclear cells through autocrine and paracrine
and plays important roles in fibrosis of granulomas.
