A study about the impact of overpression of Oct4 and Sox2 gene on gastric cancer cell biology and oncology characteristics [PDF]
目的:通过构建过表达干细胞因子Oct4和Sox2的胃癌SGC7901细胞株,研究过表达干细胞因子Oct4和Sox2对SGC7901胃癌细胞干细胞特性、肿瘤学特性、及生物学特性的影响,并探讨Oct4及Sox2在肿瘤细胞中的作用机制。 方法:1.构建携带Sox2基因的重组质粒,慢病毒载体感染SGC7901-OCT4细胞株得到SGC7901-OCT4-SOX2稳转细胞株。2.利用荧光定量PCR、western–bloting检测过表达Oct4及Sox2的胃癌SGC7901细胞中胃癌干细胞标志基因表达情况。3 ...

<正>从世界范围看,头颈部恶性肿瘤的发病率较高,口腔恶性肿瘤属于头颈部肿瘤,位居全身恶性肿瘤的第六位。在我国,口腔颌面部的恶性肿瘤以鳞状细胞癌最为多见,占80%以上。口腔癌(OSCC)转移是导致患者死亡的主要原因,在肿瘤转移的过程中,肿瘤细胞诱导血管的形成、肿瘤细胞黏附能力的变化、破坏细胞外基质(ECM),肿瘤细胞的运动能力和逃避免疫监视对肿瘤的转移也起了重要作用。

DNA Methylation and Non-small Cell Lung Cancer [PDF]
Genomic DNA methylation is a major form of epigenetic modification. Hypermethylation could affect the binding of transcription factors to DNA and change the structure of chromatin resulting in silence of tumor suppressor genes, which plays an important ...

Sugar-targeted theranostics for research on localization of tumors [PDF]
随着癌症发病率和死亡率的日益提高,发展一种辅助癌症治疗的技术具有重要的临床意义。手术切除是治疗癌症的首选方式之一。医生在进行手术切除时常因为无法精确定位肿瘤而造成肿瘤的多切或少切,继而导致肿瘤的复发。为此,人们积极探索光学探针来辅助医生分辨肿瘤。为了获得高的信噪比,光学探针需要与一些靶向基团连接,常用的靶向基团有抗体、叶酸、多肽及核酸适配体等。而糖分子作为一种靶向基团用于术中肿瘤的成像却不曾有研究。肝细胞癌往往形成4-8cm时才能出现一定的特征,所以人们无法发现微小尺寸的肝癌病灶。目前临床上 ...

N-Myc-Interacting Protein (NMI)蛋白抑制胃癌上皮间质转化(EMT)的研究 [PDF]
上皮间质转化(EMT)与多种生长因子和转录因子相关,可以通过多种信号转导通路起作用,并在胚胎发育、损伤修复、许多慢性疾病及肿瘤的发生和发展中起着重要的作用,然而EMT在胃癌发生过程中的分子机制并不清楚。 核因子-κB(NF-κB)可以与多种基因启动子部位的κB位点发生特异性的结合并促进其转录表达,进而调控肿瘤的发生,影响EMT的进程。我们的工作发现了一个新的通过调控抑制NF-κB通路调控胃癌中EMT的蛋白-NMI(N-MycandSTATinteractor)。研究结果显示 ...

IL-6 promotes Epithelial-Mesenchymal Transition and increases metastasis in lung cancer cells via the activation of ATM/NF-kappaB pathway [PDF]
【背景和目的】恶性肿瘤的侵袭和转移是导致治疗失败的关键因素。IL-6作为重要的促炎因子,参与了肿瘤发生发展的全过程,是肿瘤相关炎症的关键分子。我们之前的研究发现,IL-6可以在肺癌中激活ATM-NF-κB通路、促进MMPs的表达及活性,并可以介导肿瘤细胞的侵袭和迁移。肿瘤转移涉及肿瘤微环境各组分的相互作用,包括肿瘤细胞自身发生了形态、极性、能动性改变,即上皮间质转换(EMT)的发生。EMT赋予细胞迁移和侵袭以及诱导为干细胞的性质,阻止了细胞的衰老和凋亡,并促成了免疫抑制微环境的形成 ...

99Tcm-N(NOEt)2 Uptake Kinetics Difference among KMB17 Human Embryonic Lung Diploid Fibroblast and Different Human Lung Cancer Cells [PDF]
Background and objective PET/CT imaging is expensive, so searching the tumor imaging agent for SPECT/CT is necessary. 99Tcm-N(NOEt)2 [bis (N-ethoxy-N-ethyl dithiocarbamato) nitrido99Tcm (V)] can be uptaken by lung cancer cells and other cells alike.
