环状RNA(circular RNA,circ RNA),作为非编码RNA(non-coding RNA)的重要成员,广泛存在于包括人类在内的多种原核及真核生物体内,对生命活动具有重要的调控作用,已成为非编码RNA研究领域的热点。与线性RNA相比,circ RNA呈共价闭合环状结构,具有结构稳定、序列保守、组织特异性、时空特异性等特点,在包括消化道肿瘤在内的多种疾病中发挥重要作用。circ RNA可通过竞争性吸附mi RNA、调控基因表达、参与蛋白质翻译等多种途径,参与肿瘤的发生发展,在肿瘤早期诊断 ...

目的研究FGG蛋白在结直肠癌及其周围的癌旁组织的表达情况,探讨FGG在结直肠癌中的临床意义,以及评价作为该病肿瘤标志物的潜力。方法应用液质联用技术,分析结直肠癌中表达的差异蛋白情况,利用Western blot方法对其准确性进行验证。结果经质谱鉴定后得出FGG在结直肠癌中较正常组织中表达增高,Western blot结果与之吻合。结论可将FGG视为结直肠癌病情监测以及疗效预测中的潜在标志物之一。

Prokaryotic expression of DHX32, preparation of monoclonal antibodies and the establishment of its detection method [PDF]
RNA螺旋酶可以通过水解三磷酸腺苷(ATP)供能来催化RNA双链解螺旋,在RNA代谢中发挥重要作用。DHX32是新发现的一种RNA螺旋酶,其广泛分布于体内组织,目前发现DHX32存在两种转录本,一种为DHX32全长,另一种通过可变剪切产生exon4缺失转录本(DHX32Δ4)。有研究表明,DHX32能改变JurkatT细胞对Fas信号的敏感性,通过下调c-FLIPshort的表达,从而促进JurkatT细胞凋亡。有研究表明,DHX32在结直肠癌中上调,且可以促进细胞生长及迁移,而最新的研究提示 ...

Research of Esophagus Disease-aided diagnosis Based on Ultrasonic Endoscope Image [PDF]
食管疾病是常见疾病之一,对人们的健康产生了严重的威胁。随着超声内镜(EUS)应用的发展和普及,提高了食管成像清晰度,成为临床诊治的必要诊断工具。超声内镜可为食管疫病的诊断及给出合理的治疗方案给予非常大的帮助,但是国内外对EUS诊断主要依靠内镜医师个人经验,缺乏客观诊断依据,因此使得EUS的应用受到限制。由此看来利用计算机技术对食管疾病进行辅助诊断是非常有意义的。 本文主要研究三类食管EUS图像分类的问题,包括食管早癌、食管平滑肌瘤以及正常食管。首先对EUS图像进行去噪处理,之后提取EUS图像的特征点 ...

The effects of axon guidance factor Slit3 on metastasis of human fibrosarcoma [PDF]
我们通过在纤维肉瘤细胞HT1080过表达Slit3基因,分析Slit3对肿瘤细胞侵袭转移作用.Transwell侵袭实验中,Slit3过表达后抑制HT1080的迁移侵袭,在裸鼠皮下成瘤实验中,肿瘤体积明显变小、重量明显降低,Slit3过表达后抑制HT1080肿瘤细胞的侵袭转移。此外肿瘤切片HE染色后发现GFP组有病灶点,而slit3过表达则少见,这个结果说明,Slit3显著抑制HT1080细胞转移。slit3过表达后MMP2,MMP9的表达明显降低,而MMP3,MMP13表达量上调 ...
