| Objective: To investigate the course of tubular cell senescence and expressions of p53, p21, and Rb during the late phase of ischemia/reperfusion (IRI) in the kidney, and assess the effects of the p53-Rb pathway on tubular cell senescence. Methods: Experimental models of unilateral renal IRI were used in p53(+/+) and p53(-/-) mice. Histological changes at the tubular level, progress of cell senescence, and the expression of Rb, p21, and/or p53 proteins in tubular cells were studied at different moments in time after IRI. Results: Chronic tubulointerstitial fibrosis was much more severe and widely distributed in IRI kidneys of p53(+/+) mice in later stages than in earlier stages. Senescent tubular cells were significantly increased at 3 and 6 months after... |
