    DHX32 promotes angiogenesis in colorectal cancer through augmenting β-catenin signaling to induce expression of VEGFA

    肿瘤的生长和转移离不开肿瘤血管生成,因此抗血管生成是目前肿瘤治疗的重要途径之一,其中血管内皮生长因子VEGF及其信号通路是抗肿瘤治疗的重要靶点。DHX32是近年来新发现的一种RNA螺旋酶,对其在肿瘤发生发展中的作用研究刚刚起步。我们的前期研究表明DHX32在结肠癌中表达上调,并能够促进结肠癌细胞增殖、迁移和侵袭,抑制细胞凋亡;qPCR芯片的筛选结果显示敲低DHX32抑制了血管生成因子VEGFA的mRNA水平,预示着DHX32可能参与了肿瘤血管生成的调控。本研究发现在结肠癌细胞中DHX32通过与b-catenin结合并稳定其蛋白水平从而上调b-catenin下游靶基因VEGFA的转录;由此提高了...Colorectal cancer (CRC) is the third most common cancer worldwide and accounts for 14% of all new cancer diagnoses. Tumor angiogenesis that is required for cancer growth and metastasis by nourishing cancer cells and helping spread of metastatic cells to distant tissues has been considered as a potential target for CRC treatment. Understanding the molecular mechanism by which CRC cells promote angi...学位:理学博士院系专业:生命科学学院_生物化学与分子生物学学号:201317007

    EQCM and in-situ reflectance FTIR spectroscopic studies of adsorption and oxidation of methanol on Pt electrode in alkaline media

    Get PDF
    The adsorption and oxidation of methanol on Pt electrode in alkaline media have been investigated by using cyclic voltammetry, electrochemical quartz crystal microbalance (EQCM) and in-situ reflectance FTIR spectroscopy. The experimental results demonstrated that the electrooxidation of CH3OH was closely relative to solution acidity. Only one current peak of methanol oxidation in PGPS was detected at -0.09 V, which illustrated the disappearance of the second current peak due to Pt electrode passivation in alkaline media. The magnitude of the dissociative adsorbate of methanol in alkaline media is smaller than that in acidic media. The main product, such as CO2 and CO32-, was detected clearly and the reactive intermediates that were determined by FTIRS under experimental condition might be mainly HCOO- species. The EQCM studies provide quantitative results of surface mass changes during methanol oxidation, and have thrown new light in the elucidating methanol oxidation

    [中文文摘]用高速碰撞共沉淀法制备m(CuO) /m(ZnO) /m(Al2 O3 )比分别为 60 /3 0 /1 0和 3 0 /60 /1 0的 1 #和 2 #催化剂 ,结果表明高ZnO的 2 #催化剂活性较好 ,分散度较大。XPS测试表明 2 #催化剂表面ZnO吸附的中间体 (CHx 或CHxO)较多且表面的Cu+1浓度较高 ,从而促进CO加氢合成甲醇的活性。[英文文摘]Cu/ZnO/Al_2O_3 catalysts with ratios of 60/30/10 and 30/60/10 have been prepared by high speed collision coprecipitation method. The performance of the catalyst with the higher ZnO content shows the higher activity in methanol synthesis. The characterization results indicated that the catalyst with the higher ZnO content has higher dispersion. On the surface of the higher ZnO content catalyst, there was more Cu+1 and more intermediate (CH_x and CH_xO) adsorpted. It is beneficial for the CO hydrogenating to produce methanol

    股票流动性与股价崩盘风险:公司治理和短期行为视角

    Get PDF
    流动性究竟能够稳定市场还是给市场带来危机?文章从股价崩盘风险的视角,探讨了股票流动性与股价崩盘风险的关系,研究发现:股票流动性促进了股价崩盘风险,因而并没有起到稳定市场的作用。随后,从\"治理理论\"和\"短期行为理论\"两个角度对影响机制进行探讨,研究发现:在二职合一、独立董事比例较低、短期机构投资者持股比例较高时,股票流动性对股价崩盘风险的正向影响更加显著。研究结论既丰富了股票流动性及股价崩盘风险的相关文献,也给管理层及上市公司从微观视角认识股价崩盘风险提供新思路及借鉴。国家自然科学基金重点项目“制度环境、公司财务政策选择和动态演化研究”(71232004);;福建省中青年教师教育科研项目“基于企业创新视角的股权结构优化对策研究”(JAS170348);;厦门理工学院社会科学研究项目“产品市场竞争的治理效应实证研究——大股东掏空视角”(YSK13013R
