New role and molecular mechanism of Gadd45a in hepatic fibrosis

引用

World Journal of Gastroenterology 2016年第9期22卷 2779-2788页

作者： Liang Hong Qing-Feng Sun ting-yan xu yang-He Wu Hui Zhang Rong-Quan Fu Fu-Jing Cai Qing-Qing Zhou Ke Zhou Qing-Wei Du Dong Zhang Shuang xu Ji-Guang Ding Department of Infectious Diseases the Third Affiliated Hospital to Wenzhou Medical University Department of Infectious Diseases The First Peoples Hospital of Xiaoshan Disrict Department of Infectious Diseases Tianjin Baodi Hospital

AIM: To investigate the role of Gadd45a in hepatic fibrosis and the transforming growth factor (TGF)-beta/ Smad signaling pathway. METHODS: Wild-type male BALB/c mice were treated with CCl4 to induce a model of chronic liver injury. Hepatic stellate cells (HSCs) were isolated from the liver of BALB/c mice and were treated with small interfering RNAs (siRNAs) targeting Gadd45a or the pcDNA3.1-Gadd45a recombinant plasmid. Cellular alpha-smooth muscle actin (alpha-SMA), beta-actin, type I collagen, phospho-Smad2, phospho-Smad3, Smad2, Smad3, and Smad4 were detected by Western blots. The mRNA levels of alpha-SMA, beta-actin, and type I collagen were determined by quantitative real-time (qRT)-PCR analyses. Reactive oxygen species production was monitored by flow cytometry using 2,7-dichlorodihydrofluorescein diacetate. Gadd45a, Gadd45b, anti-Gadd45g, type I collagen, and SMA local expression in liver tissue were measured by histologic and immunohistochemical analyses. RESULTS: Significant downregulation of Gadd45a, but not Gadd45b or Gadd45g, accompanied by activation of the TGF-beta/Smad signaling pathways was detected in fibrotic liver tissues of mice and isolated HSCs with chronic liver injury induced by CCl4 treatment. Overexpression of Gadd45a reduced the expression of extracellular matrix proteins and alpha-SMA in HSCs, whereas transient knockdown of Gadd45a with siRNA reversed this process. Gadd45a inhibited the activity of a plasminogen activator inhibitor-1 promoter construct and (CAGA)(9) MLP-Luc, an artificial Smad3/4-specific reporter, as well as reduced the phosphorylation and nuclear translocation of Smad3. Gadd45a showed protective effects by scavenging reactive oxygen species and upregulating antioxidant enzymes. CONCLUSION: Gadd45a may counteract hepatic fibrosis by regulating the activation of HSCs via the inhibition of TGF-beta/Smad signaling.

装备差动助力转向(DDAS)系统的汽车匹配主动前轮转向(AFS)系统时,两者会相互干扰。DDAS助力时引入的横摆力偶矩会影响车辆的转向特性,反之,AFS的介入会导致转向盘转矩突变。为此,本文提出了一种差动协同主动转向(DDCAS)系统。首先,介绍了DDCAS系统的结构和动力学模型;然后,分别制定了DDAS和AFS的控制策略,分析了两系统的干扰机理,并制定了DDCAS控制策略。最后,在Matlab/Simulink与CarSim联合仿真平台上进行了典型工况的仿真分析,验证了本文控制策略的有效性。

探讨五味子基于microRNA-124(miR-124)调控Toll样受体4(Toll-like receptor 4,TLR4)通路介导小胶质细胞表型转化的作用机制。利用脂多糖(lipopolysaccharide,LPS)刺激BV2细胞建立模型,不同剂量五味子提取物(Schisandra Chinensis extract,SCE)处理细胞;miR-124抑制剂(miR-124 inhibitor)和阴性对照序列(NC inhibitor)转染至BV2细胞后用SCE处理细胞。MTT法检测细胞活性;NO试剂盒检测NO释放量;ELISA检测白细胞介素-10(interleukin-10,IL^(-1)0)、肿瘤坏死因子-α(tumor necrosis factor-α,TNF-α)含量;免疫荧光染色法检测小胶质细胞标志物离子钙结合接头分子-1(ionized calcium binding adapter molecule-1,IBA-1)、精氨酸酶-1(arginase-1,Arg-1)及下游核转录因子κB(nuclear factor-kappa B,NF-κB)核移位的影响;Western blot检测NF-κB p65、IBA-1、Arg-1、TLR4、骨髓分化蛋白88(myeloid differentiation primary factor 88,MyD88)、核因子抑制蛋白-α(nuclear factor inhibitor protein-α,IκB-α)、IκB激酶-α(inhibitor of nuclear factor-kappa B kinases-α,IKK-α)、IL-10、TNF-α等蛋白的表达。质量浓度为31.25~250μg·mL^(-1)的SCE对于细胞活性无明显影响;SCE作用后,NO释放受到抑制(P<0.001,P<0.01),IL-10释放水平升高(P<0.05),而TNF-α释放水平降低(P<0.001),同时抑制TNF-α、IBA-1、TLR4、MyD88蛋白的表达(P<0.01,P<0.001),升高IL-10、Arg-1、NF-κB p65、IKK-α蛋白表达(P<0.001,P<0.01,P<0.05),SCE还能够促进miR-124的表达(P<0.01);转染miR-124 inhibitor后,TNF-α释放量升高(P<0.001),IL-10释放量减少(P<0.05),TNF-α、IBA-1的mRNA和蛋白表达升高(P<0.05,P<0.01,P<0.001),IL-10、Arg-1 mRNA和蛋白表达降低(P<0.001,P<0.01),同时抑制TLR4、MyD88的激活作用减弱。SCE可能通过上调miR-124抑制TLR4信号通路的激活从而抑制小胶质细胞M1极化,促进小胶质细胞M2极化。

【目的】通过分析肝细胞癌(HCC)MRI的主要征象与不同组织学分化程度之间的关系,探讨MRI在评价肝细胞癌组织学分化程度中的价值。【方法】将病理证实的229例HCC分为3组:高分化组(34例),中分化组(170例),低分化组(25例)。均行常规MRI及DWI检查,分析HCC瘤灶主要征象与HCC组织学分化程度的关系。【结果】229例HCC中(1)HCC瘤灶的分叶程度与组织学分化程度之间呈较弱的负相关关系(r=-0.37,P=0.000);HCC的T1WI信号强度与组织学分化程度之间呈较弱的正相关关系(r=0.292,P=0.000);HCC的T2WI信号强度与组织学分化程度之间呈较弱的负相关关系(r=-0.207,P=0.002)。HCC的DWI目测信号强度与组织学分化程度之间呈较弱的负相关关系(r=-0.317,P=0.000)。(2)HCC的"包膜"完整性,血供方式与组织学分化程度之间无显著相关关系(P>0.05)。(3)在HCC瘤灶的分叶程度、T1WI信号强度、T2WI信号强度和DWI目测信号强度中,HCC瘤灶的分叶程度是影响组织学分化程度的最显著因素(OR1=0.15,OR2=0.25,P<0.05)。【结论】MRI中HCC的分叶程度、T1WI、T2WI、DWI的目测信号强度有利于预测HCC组织学分化程度,其中HCC分叶程度为最主要的征象;然而,根据常规MRI检查及DWI的目测信号强度,而正确预测HCC的组织学分化程度是有限的,应该综合多种征象分析。
