ABSTRACT
Objective To investigate the effects of HO-1 on renal allografts after HO-1 gene transfection in rat chronic allograft nephropathy model. Methods Twenty F344 and twenty-six Lewis rats were included in this experiment. They were divided into 3 groups at random. Six Lewis rats were in pseudo-operation group, 10 Lewis were in empty carrier group (transfected with adenovirus) and 10 Lewis were in the gene transfection group (transfected with Ad-HO-1 adenovirus). The expression of HO-1 protein was detected by WB at the 1st ,2nd,3rd and 4th week. The content of creatinine in blood was assayed at the 4th,8th, 12th and the 16th week. The weight of rat, the value of patholiogical changes and the expression of ?-SMA,TGF-?1 and PDGF-B were analysized at the 16th week. Results The weight of rats in 3 groups had not any changes at 16th week. The content of creatinine in blood of gene transfection group were lower than those in the empty carrier group. The expression of HO-1 protein were very high in the 1st and 2nd week and decreased at 3rd and 4th week. The Banff value of kidney in the gene transfer group was better than that of the empty carrier group at the 16th week. The level of ?-SMA, TGF-?1 and PDGF-B in the gene transfection group were significantly lower than those in the empty carrier group. Conclusions Ad-HO-1 could efficiently transfer HO-1 gene into rat donor kidney. The prevention of chronic allograft nephropathy may have relationship with the decreasing expression of ?-SMA, TGF-?and PDGF-B.
