    • 摘要: Objective To observe the relationship between the degree of renal interstitial injury and the expression levels of P2X4 and NALP3 in diabetic nephropathy (DN). Methods Forty-five DN patients were assigned to observation group and 40 ones undergoing renal hamartoma resection to control group. Biochemical indicators and the expression levels of P2X4,NALP3,IL-1β and IL-18 in renal tubular epithelial cells were compared between 2 groups. Results The levels of urea nitrogen,serum inosine and urinary protein were significantly higher (P<0.01) and those of plasmatotal protein,albumin and glomerular filtration rate lower (P<0.01) in observation than in control group. Findings of immunohistochemisty fluorescence showed that P2X4,NALP3,IL-1β and IL-18 were all high expression in observation group;findings of laser confocal microscope showed that the expressions of P2X4,NALP3,IL-1β and IL-18 all reinforced in observation group. Both P2X4 and NALP3 were significantly positively related to urea nitrogen,serum inosine,urine protein,renal interstitial inflammation,renal interstitial fibrosis,kidney tubules atrophy,IL-1β and IL-18 (P<0.05) and negatively to glomerular filtration rate (P<0.05). Conclusion The expression levels of P2X4 and NALP3 are positively related to damage degrees of renal interstitial inflammation significantly and can be used as a new monitoring index to provide basis for clinical diagnosis,treatment and prognosis.%目的 观察糖尿病肾病患者肾间质损伤程度与P2X4、NALP3表达水平变化的相关性.方法 将45例糖尿病肾病患者设为观察组,40例肾错构瘤行切除术患者设为对照组.比较两组生化指标水平及肾小管上皮细胞P2X4、NALP3、白细胞介素-1β、白细胞介素-18的表达水平.结果 观察组尿素氮、血清肌苷、尿蛋白水平显著高于对照组(P<0.01),血浆总蛋白、血浆清蛋白、肾小球滤过率水平显著低于对照组(P<0.01).免疫组化荧光结果显示观察组P2X4、NALP3、白细胞介素-1β、白细胞介素-18均为高表达;激光共聚焦结果显示观察组P2X4、NALP3、白细胞介素-1β、白细胞介素-18表达均显著增强.观察组P2X4和NALP3分别与尿素氮、血清肌苷、尿蛋白、肾间质炎症、肾间质纤维化、肾小管萎缩、白细胞介素-1β和白细胞介素-18呈显著正相关(P<0.05),与肾小球滤过率呈显著负相关(P<0.05).结论 P2X4和NALP3的表达水平与肾间质炎症损伤程度存在显著正相关,可以作为一种新的监测指标,为临床诊断、治疗与预后评价提供参考依据.

    • 摘要: Objective To investigate the roles of microRNA-382 (miR-382) in the pathogenesis of renal tubulointerstitial fibrosis (TIF).Methods Human kidney epithelial cells (HK2)transfected with miR-382 inhibitor (antagomiR-382) were used to examine the effect of miR-382 abundance on cell polarity,as well as to test the complementary relationship between miR-382 and its predicted target gene heat shock protein 60 (HSPD1),which was further verified by 3'-untranslated region luciferase assay and site-directed mutagenesis.The role of miR-382 played in the development of renal interstitial fibrosis and redox regulation was examined in a mouse unilateral ureteral obstruction (UUO) model.Locked nucleic acid (LAN)-modified anti-miR-382 was intravenous delivered via tail vein 30 min prior to UUO,and repeated the dosage 24 h after the surgery.For clinical verification,renal biopsy specimens from 12 IgA nephropathy (IgAN) patients were collected,6 patients with moderate to severe TIF and 6 patients without TIF.The relative abundance of miR-382 and HSPD1 protein was analyzed by using in situ hybridization and immunohistochemistry.Results HSPD1 was confirmed to be a new,direct target gene of miR-382 by in vitro 3'-untranslated region luciferase assay and sitedirected mutagenesis.The development of epithelial transition in HK2 cells was accompanied with upregulation of miR-382 [(6.54±0.96) vs (1.12±0.26),P < 0.05].Blocking the expression of miR-382 could reversed the progression of epithelial transition partially.In UUO mice the abundance of miR-382 was up-regulated [(6.89 ± 2.47) vs (1.00±0.42),P < 0.01] while HSPD1 and Trx were downregulated compared with the sham group.Down-regulation of miR-382 was associated with significant decrease in TIF,but increase in HSPD1 and thioredoxin protein compared with UUO group [HSPD1:(0.34±0.10) vs (0.14±0.05);Trx:(0.79±0.18) vs (0.36±0.16);all P < 0.05].The expression of miR-382 was up-regulated and HSPD1 was significantly down-regulated in IgAN patients with TIF.Conclusions miR-382 play an important role in renal tubulointerstitial fibrosis in human and mice.HSPD1 is one of the target genes of miR-382.The down-regulation of HSPD1 and the decrease ability of anti-oxidative stress may be the important mechanism of miR-382 involved in renal tubulointerstitial fibrosis.%目的 研究微小RNA-382(miR-382)在肾小管间质纤维化(TIF)发病中的作用及相关机制.方法 通过抑制miR-382的表达,观察其丰度对人近端肾小管上皮细胞(HK2)转分化的影响,并验证miR-382与其预测靶基因热休克蛋白60(HSPD1)的互补配对关系.建立小鼠单侧输尿管梗阻(UUO)模型,经尾静脉注射锁核苷酸(LAN)修饰的anti-miR-382,观察抑制miR-382表达对梗阻侧肾小管间质病变及肾组织硫氧还原蛋白(Trx)水平的影响.收集有和无明显TIF的IgA肾病(IgAN)患者肾穿刺标本各6例,原位杂交和免疫组化法检查TIF程度及抗氧化应激水平,分析其与miR-382/HSPD1表达的相关性.结果 体外荧光素酶报告基因检测和定点突变实验结果证实HSPD1为新的miR-382对应的直接靶基因.TGF-β1诱导HK2细胞发生转分化,与对照组相比,TGF组miR-382表达水平显著上调[(6.54±0.96)比(1.12±0.26),P< 0.05];阻断miR-382可使TGF-β1诱导的上皮转分化部分被逆转.体内实验结果表明,UUO模型组小鼠发生明显TIF病变,与假手术组相比,模型组miR-382丰度明显上调[(6.89±2.47)比(1.00±0.42),P< 0.05],HSPD1和Trx蛋白表达水平明显下调.10 mg/kg LNA-anti-miR-382干预组miR-382表达下调,梗阻侧肾组织TIF程度减轻,HSPD1和Trx的蛋白表达水平上调(均P< 0.05).IgAN患者肾组织检查结果提示,与无纤维化组相比,纤维化组肾组织miR-382丰度明显上调,HSPD1蛋白表达水平则明显降低(均P<0.05).结论 miR-382在人类及小鼠TIF发病中起重要作用,HSPD1是miR-382的直接靶基因.HSPD1表达下调导致相应的抗氧化应激能力减弱可能是miR-382参与TIF的机制之一.
