| 1 | Role of Nrf2 in chronic liver disease显示文摘Nuclear erythroid 2-related factor 2(Nrf2) is a central regulator of antioxidative response elements-mediated gene expression. It has a significant role in adaptive responses to oxidative stress by interacting with the antioxidant response element, which induces the expression of a variety of downstream targets aimed at cytoprotection. Previous studies suggested oxidative stress and associated damage could represent a common link between different forms of diseases. Oxidative stress has been implicated in various liver diseases, including viral hepatitis, nonalcoholic fatty liver disease/steatohepatitis, alcoholic liver disease and drug-induced liver injury. Nrf2 activation is initiated by oxidative or electrophilic stress, and aids in the detoxification and elimination of potentially harmful exogenous chemicals and their metabolites. The expression of Nrf2 has been observed throughout human tissue, with high expression in detoxification organs, especially the liver. Thus, Nrf2 may serve as a major regulator of several cellular defense associated pathways by which hepatic cells combat oxidative stress. We review the relevant literature concerning the crucial role of Nrf2 and its signaling pathways against oxidative stress to protect hepatic cell from oxidative damage during development of common chronic liver diseases. We also review the use of Nrf2 as a therapeutic target to prevent and treat liver diseases. | Wei Tang Yong-Fang Jiang Murugavel Ponnusamy Mamadou Diallo | 2014 | World Journal of Gastroenterology2014,20,36: | 14 |
| 2 | 核因子E2相关因子2与细胞自噬对肝纤维化的影响显示文摘肝纤维化是慢性肝病发展到肝硬化的必经阶段,在全世界范围保持着较高的发病率。肝纤维化的发生机制复杂,其发生发展受到许多细胞因子及信号通路的影响,人们对肝纤维化的认识也越来越深入。简述了核因子E2相关因子2(Nrf2)介导的抗氧化应激系统在对抗各种类型肝纤维化中的作用和细胞自噬对肝纤维化的影响,以及Nrf2和自噬的相互影响在肝纤维化中可能的作用机制。认为将Nrf2和细胞自噬联合研究是未来肝纤维化发生机制的研究方向,为肝纤维化的治疗提供了新思路。 | 王维昊 许伟华 | 2015 | 临床肝胆病杂志2015,31,3: | 3 |
| 3 | HO-1与HCV的相关性研究显示文摘血红素加氧酶-1(hemeoxygenase-1,HO-1)在肝脏和脾脏高表达,可以被包括某些病毒感染在内的多种因素诱导表达,具有抗氧化、抗炎、抗凋亡等保护作用。丙型肝炎病毒(hepatitisCvirus,HCV)感染可以造成慢型肝炎、肝硬化和肝癌等疾病,对人类健康造成很大威胁。研究发现HO-1通过影响HCV的复制发挥其保护作用,同时HCV也可以反向调控HO-1的表达。尽管HO-1与HCV相互作用的分子机制还不明确,但H0—1与HCV感染相关性研究不断取得重大进展,将为HCV感染的治疗提供一种新方法。 | 刘庆军 陈赣 周虹 | 2010 | 医学分子生物学杂志2010,7,4: | 1 |
| 4 | Nrf2对肝癌及癌前病变的作用研究进展显示文摘随着社会的进步,人类的生活方式也发生了改变.在消化系统疾病中,肝癌的发病率呈增高趋势,并严重影响着人类的身体健康.肝癌的发生是多过程、多阶段的分子生物学过程,在肝癌的发生过程中,重要的几个促癌因素有乙型肝炎病毒(HBW)、丙型肝炎病毒(HCV)、黄曲霉毒素及化学致癌物质等,而具体到分子层面主要为原癌基因和抑癌基因的失衡、 | 王晓刚 韩春姬 | 2011 | 延边大学医学学报2011,34,3: | 0 |
| 5 | 铁离子在脊髓损伤后继发性损害中的作用及铁螯合剂的干预作用的研究显示文摘脊髓损伤是中枢神经系统的严重创伤,一直是医学研究的热门课题。脊髓损伤分为原发性损伤和继发性损伤,阻止或减少继发性损伤是治疗的关键。铁离子介导的脂质过氧化被认为是脊髓损伤致残的重要原因之一,本文就铁离子在中枢神经系统的分布和功能,脊髓中与铁转运和储存相关蛋白的结构及在铁转运过程中的作用,及脊髓损伤后由于脊髓内出血,红细胞破坏增多,游离铁的浓度增高,导致铁超载,加重脊髓损伤后继发性损害的作用机制进行阐述,并对铁螯合剂去铁敏的性质,代谢过程,及在脊髓损伤后继发性损害中的作用机制和对神经细胞的保护作用作一综述。 | 王衍廷 袁绍纪 冯华 | 2009 | 国际神经病学神经外科学杂志2009,36,5: | 0 |
