ABSTRACT
This study aims to explore the effect of PKC-α gene silencing on the occurrence of ultrafiltration failure (UFF) in peritoneal dialysis (PD) rats. Forty-eight male SD rats were collected to establish 5/6 renal resection uremic and uremic PD rats models. Rats were assigned into control, sham operation, uremia, PD-2 W (peritoneal dialysis for 2 weeks), PD-4 W (peritoneal dialysis for 4 weeks), negative control (NC) (peritoneal dialysis for 4 weeks, and injected 0.1 mg/kg blank plasmid into abdominal cavity) and PKC-α siRNA (peritoneal dialysis for 4 weeks, and injected 0.1 mg/kg PKC-α siRNA into abdominal cavity) groups. CD34 staining was performed to determine microvessel density (MVD) for peritoneal tissues. The mRNA and protein expression of PKC-α in peritoneal tissue were detected by qRT-PCR and Western blot. Compared with the control group, MVD, the mRNA and protein expression of PKC-α were significantly increased in rats of the uremia, PD-2 W, PD-4 W, NC, and PKC-α siRNA groups. Compared with the uremia group, MVD, the mRNA and protein expression of PKC-α were increased, the changes observed in the PD-4 W and NC groups were better obvious than in the PD-2 W group. In comparison with the PD-4 W and NC groups, MVD, the mRNA and protein expression of PKC-α in rats were decreased in the PKC-α siRNA group. PKC-α gene has a high expression in uremic PD rats, and PKC-α gene silencing is able to increase UF while decrease MVD and glucose transport in peritoneal tissues thus reversing UFF in PD rats. J.
