Identification of Candidate Plasma Altered miRNA Associated with Bone Metastasis of Lung Cancer [PDF]

open access: yes, 2016
目的:应用高通量miRNA芯片及荧光定量PCR技术筛选及鉴定肺癌骨转移血浆中差异表达的miRNA。 方法:搜集2013至2015年在厦门大学附属第一医院入院的45例肺癌病人外周血标本。选取4例肺癌骨转移与4例肺癌无骨转移病人血浆,应用miRNA芯片技术对差异表达的miRNA进行筛选。应用IPA分析差异miRNA参入的信号通路。应用Real-timePCR检测候选差异表达miRNA,进行验证。 结果:通过比对,成功建立了肺癌骨转移与肺癌无骨转移血浆miRNA芯片表达谱,筛选出了12个差异表达miRNA ...

Gender Dimensions of Support for Local Policy: Resident, Policymaker, and Policy Gender

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT There is a well‐established triadic relationship between satisfaction with public services, trust in leaders, and policy support in developed democracies. This study takes a novel approach by considering how gender is associated with the strength and direction of these connections, an element underexplored in the literature.

β-连环蛋白在卵巢癌组织中的表达

open access: yesZhongguo shiyan zhenduanxue, 2007
目的探讨β-连环蛋白(β-cat)在卵巢癌组织中的表达及意义。方法①应用4097点基因芯片对5例卵巢癌及5例正常卵巢组织进行基因表达谱分析,筛查差异表达基因。②对60例卵巢癌组织、24例卵巢瘤组织及24例正常卵巢组织石蜡标本进行免疫组织化学方法染色,检测β-cat的表达情况,分析β-cat的表达与临床分期及组织分级的相关性。结果①基因芯片筛查出卵巢癌差异表达基因58个,其中基因表达增高(上调趋势)30个,基因表达降低(下调趋势)28个,β-cat为表达增高基因。②β ...

The Crosstalk and Regulation of Nur77 、RXRα and Cancer [PDF]

open access: yes, 2012
核受体是真核细胞生物体内一类重要的蛋白质,在机体正常生命活动过程中发挥着极其重要的作用;然而,核受体表达和功能的异常会导致严重的人类疾病。这里,我们主要研究了两种核受体Nur77和RXRα在肿瘤发生中的作用及其机制。 在第一章中,我们主要研究了孤儿核受体Nur77在结肠癌发生中的作用及其调控。孤儿核受体Nur77属于核受体超家族的重要一员,易被诱导表达。研究表明,Nur77在多种人类肿瘤中高表达,提示它与肿瘤发生紧密相关;然而,其潜在的调控机制及生物学功能尚不清楚。在本章中 ...

Unpacking Welfare Deservingness Theory: Evidence From the Perceived Deservingness of Gig Workers

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT The theory of welfare deservingness provides valuable insights into the social legitimacy of welfare programs and the principles underlying policy design. In examining the question of who deserves what and why, established deservingness criteria emphasize that individuals demonstrating motivation to work (“reciprocity”) are typically perceived

GATA4在肝癌细胞中的表达及其对肝癌细胞增殖、迁移和侵袭能力的影响

open access: yesZhongguo shiyan zhenduanxue, 2019
目的探索转录因子GATA4在肝癌细胞系中的表达及其表达改变对肝癌细胞增殖、迁移和侵袭能力的影响。方法通过RT-PCR和Western Blot检测正常肝细胞、肝癌细胞系的表达,在体外构建GATA4基因沉默和过表达模型,分析并比较转录因子GATA4表达变化对肝癌细胞增殖、迁移和侵袭的影响。结果 GATA4mRNA在肝癌细胞系(SMMC7721、Hep3B)中高表达,在正常肝细胞HLLP-7702和HepG2中低表达,GATA4蛋白在正常肝细胞(HL-7702)和肝癌细胞系(SMMC7721 ...

Transgenic overexpression of miR-466a significantly disturbs OREBP/NFAT5 renal expression and induces phenotypes that resemble diabetes insipidus in human [PDF]

open access: yes, 2012
目的miR-466(a/b/c/e)-5p/3pmiRNAs是两组高度保守的miRNAs,其中-5p组间和-3p组间miRNAs的序列几乎完全一样。生物信息学分析和我们的前期研究显示,miR-466miRNAs可能可以在肾组织中对渗透应激调控转录因子OREBP/NFAT5进行转录后表达调控。我们因此希望研究miR-466a在转基因小鼠中的过表达对小鼠肾组织OREBP/NFAT5的表达和小鼠尿液浓缩机制的影响。 方法通过PCR从小鼠基因组中扩增miR-466a基因序列,将片段插入鸡 ...

Emotion and the Advocacy Coalition Framework: An Affective Dynamics Perspective

open access: yesPolicy Studies Journal, EarlyView.
ABSTRACT Despite extensive evidence that emotion and cognition are deeply intertwined, the Advocacy Coalition Framework (ACF) lacks an analytically independent emotional mechanism in its causal architecture—an omission that may be particularly consequential in policy subsystems structured around morally charged, identity‐laden policy disputes.

α微管蛋白在非小细胞肺癌中的表达及临床意义

open access: yesZhongguo shiyan zhenduanxue, 2012
目的探讨α微管蛋白(α-tubulin)在非小细胞肺癌(non-small cell lung cancer,NSCLC)中的表达及其临床意义。方法通过组织芯片技术及免疫组化方法检测91例NSCLC手术切除后的石蜡标本中α-tubulin表达状况,并与患者临床病理资料及预后进行统计分析。结果α-tubulin在NSCLC肿瘤细胞胞浆中存在广泛表达,其中38.46%(35/91)为高表达;≤55岁患者中α-tubulin高表达者显著高于>55岁患者(χ2=6.267,P=0.012 ...

Effects of ApoE Isoforms Expression on Brain ApoE Lipidation and Amyloid-β Accumulation [PDF]

open access: yes, 2015
在编码人三种不同apoE蛋白亚型(E2、E3和E4)的APOE等位基因(ε2、ε3和ε4)中,APOEε4等位基因是阿尔茨海默病(Alzheimer’sdisease,AD)最重要的遗传风险因子,APOEε2等位基因则具有保护作用。鉴于apoE蛋白亚型对基于调节apoE蛋白表达的AD治疗可能会有不同的影响,我们通过在人APOE基因定位替换(Targetedreplacement,TR)小鼠脑中过表达不同的人apoE亚型,研究脑中表达不同apoE亚型对apoE脂化和β-淀粉样蛋白(Amyloid-β,Aβ)
