Renal denervation reduces renal senescence and the expression of proinflammatory cytokines after kidney injury. Renal denervation (DNx) or sham operation was performed 2 days before the UUO or UIRI model in the left kidneys of mice. (A, B) Representative Western blot of senescence-related proteins p53, p21, and γ-H2AX in sham-operated, UUO/UIRI, and DNx+UUO/UIRI kidneys with densitometry analysis (C, D). (E, F) mRNA expressions of senescence-related markers p53, p21, p16, HMGA2, H2AX, and senescence-associated secretory phenotype (SASP) TGF-β1, IL-6, IL-8, and IL-1β in the kidney tissue of sham-operated, UUO/UIRI mice, and DNx+UUO/UIRI mice as shown by qRT-PCR analysis. n=3–10 in each group. *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001. Bars represented means ± SEM.
