Apobec-1重组腺病毒治疗肾性高脂血症的实验研究
Experimental study of Apobec-1 recombinant adenovirus in treatment of renal hyperlipemia
摘要
Abstract
Objective To explore the effect of the liver acquired expression of apolipoprotein B editing catalytic polypeptide-1 (Apobec-1) on hyperlipidemia of renal disease. Methods Thirty healthy ordinary level male New Zealand rabbits were randomly divided into three groups: sham operation group, nephropathy group, and Apobec-1 treatment group (Each group has 10 rabbits). Adapt feeding for one week, nephropathy group and Apobec-1 treat-ment group underwent left nephrectomy, and one week later, adriamycin (4 mg / kg) was used to construct the ne-phropathy model by ear vein injection. The eleventh week after operation, apobec-1 recombinant adenovirus (1 × 1013 Virus/ kg) was injected by ear vein in apobec-1 treatment group. The twelfth week after operation, all rabbits were sacrificed. Right kidney, liver, blood and 24h urine were left. In three groups, 24 hour urinary protein (24UPr), albumin (Alb), blood urea nitrogen (BUN), creatinine (Cr), blood lipid were detected. Renal pa-thology was observed by HE staining. Expressions of liver apobec-1, apolipoprotein B48(ApoB48)were observed by Western blot. Results ① Compared with the sham operation group, nephropathy group showed that 24UPr, BUN, Cr, total cholesterol (TC), total triglyceride (TG), very low density lipoprotein (VLDL-C), low density lipoprotein (LDL-C), apolipoprotein B100 (ApoB100) were increased(P < 0. 05), but Alb was decreased(P <0. 05). ② Compared with the nephropathy group, Apobec-1 treatment group showed that TC, TG, VLDL-C, LDL-C, ApoB100, ApoB48 were decreased(P < 0. 05). ③ Compared with the sham operation group, Apobec-1 treat-ment group showed that 24UPr, BUN, Cr were increased( P < 0. 05), but Alb, ApoB48 were decreased( P <0. 05). ④ Compared with the sham operation group and nephropathy group, Apobec-1 treatment group showed that the expression of Apobec-1 and ApoB48 were up-regulated (P < 0. 01). Conclusion When liver aquires expres-sion of Apobec-1 in hyperlipidemia of renal disease, it can reconstruct ApoB mRNA, increase the synthesis of ApoB48-lipoprotein, and play a certain lipid-lowering effect.关键词
