The expression of USP39 in non-small cell lung cancer and its function in A549 cells [PDF]
, 2016 肺癌是最常见的肺部原发性恶性肿瘤，由于其中大部分起源于支气管粘膜上皮，所以又称支气管肺癌。其中非小细胞肺癌（non-smallcelllungcancer，NSCLC）占到85%。如今肺癌已成为全世界范围内癌症死亡的首要原因，其患病率和死亡率均居各大恶性肿瘤之首。在中国，随着人口基数的快速增长以及环境污染的恶化，肺癌的死亡率在急剧上升。可见，肺癌已经成为全人类健康的重要威胁。虽然近年来各种化疗药物和手术治疗的联合应用，在一定程度上提高了治疗效果，但是由于肺癌的发病隐匿，早期诊出率低 ...

The study of AKAP95 and Cx43 protein co-regulating cell G1/S phase transition [PDF]
, 2016 本研究分为两部分，第一部分采用免疫组织化学实验，包括肺癌组织中AKAP95和CyclinD3、Akt蛋白表达与临床病理学指标的关系及3种蛋白之间的关联性分析、直肠癌组织中AKAP95、CyclinD1、CyclinE1和Cx43蛋白的关联性分析。通过检测51例肺癌组织和15例癌旁组织中细胞周期蛋白D3(CyclinD3)、蛋白激酶A锚定蛋白95(AKAP95)和丝/苏氨酸激酶(serine/threoninekinase，Akt，亦称蛋白激酶B，PKB)的表达发现，AKAP95 ...

Transcriptomic study of a toxin-producing dinoflagellate Alexandrium catenella [PDF]
, 2015 亚历山大藻（Alexandriumspp.）是一种能够产生麻痹性贝类毒素（paralyticshellfishtoxins，PSTs）的海洋甲藻，广泛分布于近海环境中。近年来由其产生的毒素导致的海洋生物死亡及人类中毒事件频发，严重威胁到近海生态系统、水产养殖业、人类健康和生命财产安全，已成为一个全球性的环境和健康问题。虽然目前在亚历山大藻毒素来源及产毒生理方面取得了较大进展，但对毒素合成机制的了解仍较少。 本论文以有毒链状亚历山大藻（Alexandriumcatenella）为研究对象 ...

The phosphorylation of BAG3 by CDK5 and its roles in astrocytes [PDF]
, 2016 细胞周期素依赖性蛋白激酶5（Cyclin-DependentKinase5，CDK5)是细胞周期蛋白依赖性丝氨酸/苏氨酸蛋白激酶家族中的一个成员，在神经系统的发育中发挥了至关重要的作用。CDK5的调节亚基P35、P39是神经系统特异性表达的蛋白，因此赋予了CDK5在神经系统中特异的激酶活性，使CDK5在调控神经递质传递，神经元凋亡等方面发挥了重要作用。对于CDK5的研究一直集中在对其新底物的发现和鉴定上，至今为止有40余个CDK5的底物被鉴定出来。作为脯氨酸依赖性蛋白激酶，CDK5可以特异磷酸化包含有 ...

The Role of Cdk5 in neuronal death and synaptic dysfunctions through phosphorylating FOXO1 and BAG3 [PDF]
, 2016 细胞周期蛋白依赖性激酶5（Cyclin-dependentkinase5，Cdk5）是由脯氨酸介导的丝氨酸/苏氨酸蛋白激酶，其在神经系统中发挥着重要的作用。Cdk5的活化主要靠神经系统中广泛表达的两个激活因子p35和p39。Cdk5对神经系统的正常生理功能具有重要作用去，其可通过磷酸化众多底物的丝氨酸/苏氨酸位点，在神经元的迁移分化，突触传递，轴突树突的发育过程以及神经元的存活中都发挥着重要的作用。此外，在某些病理条件下，Calpain所介导的p35切割形成p25，可以过度激活Cdk5 ...

The expression and function of Brg1 in ocular surface tissues under normal and disease situation [PDF]
, 2015 背景：Brahma相关基因1（Brahma-relatedgene1，Brg1）是染色质重塑复合物SWI/SNF的ATP酶亚基之一，广泛存在于真核细胞中。以往的研究表明，Brg1结合复合物参与不同类型细胞的细胞周期控制、凋亡和细胞分化。到目前为止，没有关于眼表上皮细胞Brg1表达以及功能的报道。 方法：对小鼠、兔以及人眼表组织的Brg1表达和定位进行免疫荧光染色和蛋白质印迹检测。人角膜上皮细胞株（HCE），小鼠角膜上皮细胞系（TKE2），小鼠原代培养的角膜上皮细胞（mCEC）分别在DMEM/F12+10％
