    摘要:

    目的 探索 ZBTB20 对大鼠肝星状细胞系 HSC-T6 细胞增殖和迁移的影响,为肝纤维化(HF)的治疗提供实验依据。 方法 利用 GEO 数据库分析 ZBTB20 在正常人和 HF 患者肝组织中的表达水平。 将10 只 SD 大鼠随机分为假手术(Sham)组和胆总管结扎模型(BDL)组,建立胆汁淤积性 HF 模型,通过 Western blot 实验检测大鼠肝组织中 ZBTB20 的表达水平。 通过 Western blot 实验检测 TGF-β1 刺激 48 h 后 HSC-T6 细胞中 ZBTB20 的表达水平以及纤维化标志物的表达水平;通过 RT-qPCR、Western blot 实验检测 ZBTB20 小干扰 RNA(si-ZBTB20)及过表达质粒(pcDNA3. 1-ZBTB20)的转染效率,以及 si-ZBTB20 组和 pcDNA3. 1-ZBTB20组 HSC-T6 细胞中纤维化标志物的表达水平; 通过 CCK-8、 集落形成和 Transwell 实验检测 si-ZBTB20 /pcDNA3. 1-ZBTB20 对 HSC-T6 细胞增殖、克隆形成及迁移能力的影响。 结果 ZBTB20 在 HF 患者肝组织中显著高表达。 与 Sham 组相比,BDL 组 ZBTB20 的蛋白表达水平上调,差异具有统计学意义(P<0. 05)。 与对照(control)组相比,TGF-β1 组 HSC-T6 细胞中 α-SMA、Col1A1、ZBTB20 蛋白的表达水平均显著上调,差异具有统计学意义( P<0. 05)。 RT-qPCR、Western blot 实验结果表明,与转染 si-NC 组相比,转染 si-ZBTB20 组的ZBTB20、α-SMA、Col1A1 和 CTGF mRNA 表达水平下调,ZBTB20、α-SMA 和 Col1A1 蛋白的表达水平下调(P<0. 05);与转染 pcDNA3. 1 组相比,转染 pcDNA3. 1-ZBTB20 组得到了与上述相反的结果。 CCK-8、集落形成、Transwell 实验结果表明,与转染 si-NC 组相比,转染 si-ZBTB20 组的细胞在转染 72、96 h 后,其增殖能力显著下降,细胞集落个数显著减少,且穿过 Transwell 小室基底膜的细胞数目显著降低(P<0. 05);与转染 pcDNA-3. 1组相比,转染 pcDNA3. 1-ZBTB20 组的细胞在转染 72、96 h 后其增殖能力显著升高,细胞集落个数显著增加,且穿过 Transwell 小室基底膜的细胞数目显著增加(P<0. 05)。 结论 ZBTB20 在 HF 患者肝组织中显著高表达。BDL 大鼠肝组织中 ZBTB20 表达水平升高,抑制 ZBTB20 能够抑制 HSC-T6 细胞增殖及迁移能力,过表达ZBTB20 能够促进 HSC-T6 细胞增殖及迁移能力。

    Abstract:

    Objective This study explored the effects of zinc finger and BTB domain protein 20 (ZBTB20) on rat hepatic stellate cell (HSC-T6) proliferation and migration, providing experimental evidence for hepatic fibrosis (HF) treatment. Methods ZBTB20 expression in liver tissues of normal person and HF patients were analyzed by the GEO database. Ten SD rats were randomly divided into Sham operation and common bile duct ligation (BDL) groups to establish a cholestatic HF model. Western blot assay was used to detect the expression levels of ZBTB20 in rat liver tissues. Western blot assay was used to detect the expression levels of ZBTB20 and fibrosis markers in HSCT6 cells after 48 hours of transforming growth factor TGF-β1 stimulation. RT-qPCR and Western blot assays were used to detect the expression levels of the transfection efficiency of ZBTB20 small interfering RNA ( si-ZBTB20) and overexpression plasmid (pcDNA3. 1-ZBTB20), as well as the expression levels of fibrosis markers in HSC-T6 cells in the si-ZBTB20 and pcDNA3. 1-ZBTB20 groups. The effects of si-ZBTB20 / pcDNA3. 1-ZBTB20 on HSC-T6 cells proliferation, colony formation, and migration were detected through CCK-8, colony formation, and transwell assays. Results ZBTB20 was significantly highly expressed in the liver tissues of HF patients. ZBTB20 expression levels were significantly up-regulated in the BDL group compared with the Sham group (P<0. 05). α-SMA, Col1A1, and ZBTB20 proteins were significantly up-regulated in HSC-T6 cells in the TGF-β1 group compared with the control group (P<0. 05). RT-qPCR and Western blot assay showed that ZBTB20, α-SMA, Col1A1, and CTGF mRNA expression was down-regulated in the si-ZBTB20-transfected group compared with the si-NC-transfected group, and ZBTB20,α-SMA, and Col1A1 protein expression was decreased (P<0. 05); the above indicators in the pcDNA3. 1-ZBTB20- transfected group showed opposite trends compared with the pcDNA3. 1-transfected group. CCK-8, colony formation,and Transwell assays showed that cell proliferation in the si-ZBTB20-transfected group decreased significantly after 72 and 96 hours of transfection, the number of cell colonies decreased significantly, and the number of cells passing through the basement membrane of the Transwell chamber decreased significantly compared with the si-NC-transfected group (P<0. 05); the above indicators in the pcDNA3. 1-ZBTB20-transfected group showed opposite trends compared with the pcDNA3. 1-transfected group. Conclusions ZBTB20 was significantly highly expressed in the liver tissues of patients with HF, and its expression in BDL rat liver tissues increased. ZBTB20 knockdown inhibited HSC-T6 cells proliferation and migration, while its overexpression promoted proliferation and migration.
