    Abstract

    Objective:To investigate the effects of ras responsive element binding protein 1(RREB1)on mesangial cell proliferation induced by transforming growth factor⁃β1(TGF⁃β1). Methods:Mesangial cells were cultured in vitro,and transfected with TGF⁃β1 and RREB1⁃siRNA. The proliferation activity of mesangial cells were detected by CCK⁃8. Proliferating cell nuclear antigen(PCNA), α⁃smooth muscle actin(α⁃SMA)and RREB1 mRNA levels were detected by RT⁃PCR. The expression levels of PCNA,α⁃SMA and RREB1 proteins were detected by Western blot. Cell cycles of mesangial cells were detected by flow cytometry. Results:Compared with the control group,proliferation activity of mesangial cells in the TGF⁃β1 group was significantly increased(P < 0.01). The mRNA and protein levels of PCNA,α⁃SMA and RREB1 levels in cells were significantly increased(P < 0.01). The cell cycle indicated that the percentage of S phase cells increased and the percentage of G1 phase cells decreased(P < 0.01). In RREB1⁃ siRNA +TGF ⁃β1 group,proliferation activity of mesangial cells was significantly decreased compared with TGF⁃β1 group(P < 0.01). The expressions of PCNA,α⁃SMA and RREB1 levels in cells were significantly decreased(P < 0.01). The cell cycle indicated that the percentage of S phase cells decreased and the percentage of G1 phase cells increased(P < 0.01). Conclusion:TGF ⁃ β1 induces mesangial cells proliferation by up⁃regulating RREB1 expression.

  • 3 讨论

  • HSPN是继发于HSP的肾脏损害,是儿童时期最常见的继发型肾脏病,系膜增生性病变是其主要的病理改变之一。但HSPN肾小球系膜细胞增生的病理生理机制尚未完全阐明。TGF⁃β1是一种多功能的细胞因子,能够调节细胞增殖、分化、胚胎发育及凋亡,在促进肾小球病变发生、发展过程中起重要作用[5]。TGF⁃β1可调节肾小球固有细胞增殖、促进细胞外基质(extracellular matrix,ECM)合成分泌和沉积,是体内外诱导肾小球系膜细胞活化最强有力的细胞因子[6]。目前已经被广泛应用在体外系膜细胞增殖模型的建立中。

  • 与对照组比较,* P< 0.05;与TGF⁃β1组比较,# P< 0.01。

  • PCNA即增殖细胞核抗原,是反映细胞增殖活性的重要指标,与细胞周期密切相关,存在于正常增殖细胞和肿瘤细胞增殖周期的各个时期,其表达水平随细胞增殖活性增加而升高[7]。在病理增殖情况下肾小球系膜细胞可以合成分泌大量α⁃SMA,α⁃ SMA可以进一步刺激系膜细胞增殖,促进肾脏纤维化[8]。本研究检测了PCNA及α⁃SMA的表达情况, TGF⁃β1干预后的系膜细胞上述两种蛋白表达明显升高,表明TGF⁃β1可引起系膜细胞病理性增殖。

  • 在前期研究中,我们发现HSPN患儿存在1条差异表达的多肽。通过UniProt数据库分析前体蛋白的相关信息,发现差异表达的多肽PPLVGSSALLSGTALLRPLRPKPPLLLPKPPVTE对应的前体蛋白为RREB1 [9]。RREB1是锌指转录因子的一员,能够与靶基因启动子上的ras反应元件相结合,广泛参与细胞增殖、转录调控及DNA损伤修复等生物学过程[10],在肿瘤、糖尿病、淋巴瘤及白血病等疾病中均有研究[11]。在胰腺癌患者中RREB1可激活细胞中长链非编码RNA(AGAP2⁃AS1)的转录,进而调控胰腺癌细胞的增殖和迁移[12]。在直肠癌细胞中,AGAP2⁃AS1调控Ras/MAPK通路进而影响细胞周期与增殖[13]。在肿瘤细胞中RREB1作为上皮⁃间质转化(epithelial⁃mesenchymal transition,EMT)中TGF⁃β1激活的Smad转录因子的关键伴侣,提供Ras和TGF⁃β1途径之间的分子联系,从而协同诱导发育性和纤维化EMT[14]。既往研究表明RREB1是2型糖尿病相关终末期肾病的新候选基因,且与肾小球滤过率相关,提示RREB1在肾脏损伤中发挥重要作用[15]。RREB1还可诱导以及抑制许多基因的转录,有研究表明可诱导P53[16]、抑制P16[17],而这些细胞周期调控关键基因的异常表达均参与了系膜细胞的异常增殖。但尚未有研究证实RREB1与肾小球系膜细胞增殖之间的相关性。

  • 实验发现在TGF⁃β1诱导的大鼠肾小球系膜细胞增殖中,RREB1的表达明显增加,提示RREB1在TGF⁃β1诱导的系膜细胞增殖中可能发挥作用。为了探讨RREB1是否参与了TGF⁃β1诱导的系膜细胞增殖,我们使用siRNA干扰技术,发现RREB1⁃siR⁃ NA干扰后,TGF⁃β1诱导的系膜细胞增殖受到抑制,增殖相关基因PCNA表达下调,α⁃SMA表达下调,细胞增殖活力下降,并将细胞周期阻滞于G1期,提示RREB1这一ras反应元件结合蛋白对肾小球系膜细胞的增殖具有重大影响,但其中的具体机制还有待阐明。报道表明RREB1能被Ras通路激活[18],而Ras通路在细胞增殖起主要作用。赵非等[19] 发现Ki⁃RasA⁃c⁃Raf⁃MEK⁃ERK这一信号通路独立参与了醛固酮诱导的系膜细胞增殖。miR⁃34a也通过PDGFR⁃β/Ras⁃MAPK信号通路调节系膜细胞增殖[20]。本研究中RREB1干扰后G1期细胞明显增多,提示RREB1干扰抑制肾小球系膜细胞增殖的机制可能与细胞周期阻滞相关。

  • 综上所述,在TGF⁃β1诱导的系膜细胞增殖中RREB1上调,干扰RREB1可抑制系膜细胞增殖,阻滞细胞周期,有望成为HSPN诊治的新靶标,但其中的确切机制并不明确,有待今后进一步研究。
