| 1 | Nonalcoholic steatohepatitis severity is defined by a failure in compensatory antioxidant capacity in the setting of mitochondrial dysfunction显示文摘AIM To comprehensively evaluate mitochondrial(dys) function in preclinical models of nonalcoholic steatohepatitis(NASH).METHODS We utilized two readily available mouse models of nonalcoholic fatty liver disease(NAFLD) with or without progressive fibrosis: Lep^(ob)/Lep^(ob)(ob/ob) and FATZO mice on high trans-fat, high fructose and high cholesterol(AMLN) diet. Presence of NASH was assessed using immunohistochemical and pathological techniques, and gene expression profiling. Morphological features of mitochondria were assessed via transmission electron microscopy and immunofluorescence, and function was assessed by measuring oxidative capacity in primary hepatocytes, and respiratory control and proton leak in isolated mitochondria. Oxidative stress was measured by assessing activity and/or expression levels of Nrf1, Sod1, Sod2, catalase and 8-OHdG. RESULTS When challenged with AMLN diet for 12 wk, ob/ob and FATZO mice developed steatohepatitis in the presence of obesity and hyperinsulinemia. NASH development was associated with hepatic mitochondrial abnormalities, similar to those previously observed in humans, including mitochondrial accumulation and increased proton leak. AMLN diet also resulted in increased numbers of fragmented mitochondria in both strains of mice. Despite similar mitochondrial phenotypes, we found that ob/ob mice developed more advanced hepatic fibrosis. Activity of superoxide dismutase(SOD) was increased in ob/ob AMLN mice, whereas FATZO mice displayed increased catalase activity, irrespective of diet. Furthermore, 8-OHd G, a marker of oxidative DNA damage, was significantly increased in ob/ob AMLN mice compared to FATZO AMLN mice. Therefore, antioxidant capacity reflected as the ratio of catalase:SOD activity was similar between FATZO and C57 BL6 J control mice, but significantly perturbed in ob/ob mice. CONCLUSION Oxidative stress, and/or the capacity to compensate for increased oxidative stress, in the setting of mitochondrial dysfunction, is a key factor for development of hepatic injury and fibrosis in these mouse models. | Michelle L Boland Stephanie Oldham Brandon B Boland Sarah Will Jean-Martin Lapointe Silvia Guionaud Christopher J Rhodes James L Trevaskis | 2018 | World Journal of Gastroenterology2018，24，16： | 7 |
| 2 | Prospective evaluation of small bowel preparation with bisacodyl and sodium phosphate for capsule endoscopy显示文摘AIM: To determine the effect of Prepacol?, a com- bination of sodium phosphate and bisacodyl, on transit and quality of capsule endoscopy (CE). METHODS: Fivety two consecutive patients were included in this prospective study. CE was performed following a 12 h fasting period. Twenty six patients were randomized for additional preparation with Prepacol?. The quality of CE was assessed separately for the proximal and the distal small bowel by 3 experienced endoscopists on the basis of a graduation which was initially developed with 20 previous CE. RESULTS: Preparation with Prepacol? accelerated small bowel transit time (262 ± 55 min vs 287 ± 97 min), but had no effect on the quality of CE. Visibility was significantly reduced in the distal compared to the proximal small bowel. CONCLUSION: The significantly reduced visibility of CE in the distal small bowel allocates the need for a good preparation. Since Prepacol? has no beneficial effect on CE the modality of preparation and the ideal time of application remains unclear. Further standardized examinations are necessary to identify sufficient preparation procedures and to determine the impact of the volume of the preparation solution. | Andreas Franke Frank Hummel Phillip Knebel Christoph Antoni Ulrich Bcker Manfred V Singer Matthias Lhr | 2008 | World Journal of Gastroenterology2008，14，13： | 5 |
| 3 | MicroRNA-let-7a promotes E2F-mediated cell proliferation and NFKB activation in vitro显示文摘Epigenetic 因素,包括的改变的 microRNA (miRNA ) 表示,可以在全身的豺狼座 erythematosus (SLE ) 贡献异常有免疫力的房间功能。MiRNA-let-7a (let-7a ) 被显示了直接改变房间周期前进和 proinflammatory cytokine 生产。由于在房间分割和发炎的 let-7a 的关键角色,我们调查了 let-7a-mediated 增长和 NFκ在 J774A.1 巨噬细胞和 MES 的 B translocation 在 vitro 的 13 个 mesangial 房间。在有 let-7a 的刺激免疫者的房间 transfected,房间增长显著地随着时间的过去被增加。在 S 和 G 2 阶段的刺激免疫者的房间的数字有重要增加。刺激免疫者的房间 overexpressing let-7a 增加了 NFκ 的原子 translocation; B。Bioinformatical 分析表明 E2F 家庭, G 1-S 转变的批评管理者,在他们的 mRNA 抄本为 let-7a 有潜在的有约束力的地点。Let-7a overexpression 显著地增加了房间周期使活跃之物 E2F2 的表示并且在刺激免疫者的房间增加了 retinoblastoma 蛋白质(Rb ) phosphorylation。房间周期禁止者 E2F5 显著地在刺激免疫者的 let-7a-transfected 房间被减少。Bioinformatical 分析揭示了 E2F2 和 NFκ B 是预言调整 let-7a 倡导者的抄写因素。我们与 E2F2 和 NFκ 用染色质 immunoprecipitation 由即时 RT-PCR 分析了 let-7a 的 transcriptional 规定; B 抗体。E2F2 和 NFκ 有增加;在在刺激免疫者的房间为 let-7a 倡导者充实的 DNA 的 B 绑定。Silencing E2F2 或 NFκ B 显著地减少了在刺激免疫者的房间的 let-7a 表示和 IL-6 生产。一起拿,我们的结果建议 let-7a 的 overexpression 可以在 SLE 贡献增生和 proinflammatory 反应。 | Cristen B Chafin Nicole L Regna David L Caudell Christopher M Reilly | 2014 | Cellular & Molecular Immunology2014，11，1： | 3 |
