Abstract:
Objective To investigate the effect of over-expressed Cyr61 on the expression of extracellular matrix of human renal tubular epithelial cells(HKC), and explore the role of Cyr61 in the pathogenesis and development of autosomal dominant polycystic kidney disease(ADPKD). Methods Cyr61 gene cDNA was amplified by RT-PCR. A recombinant plasmid pcDNA3.1+ Cyr61 was constructed by cloning Cyr61 gene into pcDNA3.1. HKC cells were transfected with wild-type Cyr61 plasmid vector (pcDNA3.1+Cyr61). Then the fusion of Cyr61 gene and expression of its protein were detected by RT-PCR and Western blot. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ, and laminin were determined in four groups (the untransfected cells, pcDNA3.1 transfected cells, pcDNA3.1+Cyr61 -transfected cells and cyst-lining epithelial cells) by fluorescence quantum PCR. Results The amount of Cyr61 protein in Cyr61-transfected cells and cyst-lining epithelial cells were much greater than the control. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ and laminin in Cyr61-transfected cells were all amplified significantly, and the level of collagen Ⅳwas much higher than collagen I(P
