Objective Adenocarcinomas(AC)at distal esophagus,gastroesophageal junction(GEJ)or proximal stomach have had rapidly increasing incidences in western countries during the past few decades1-3.In Asia where squamous cell carcinoma is the predominant type of esophageal cancer,rising incidence of AC at GEJ and proximal stomach have also been reported4-6.

目的 肝细胞癌(简称肝癌,Hepatocellular carcinoma,HCC)是原发性肝癌中最主要的一种,约占70-90％。肝癌是我国高发且危害重大的恶性肿瘤,新发病例数及死亡病例数均占全球50％以上。目前肝癌的治疗主要采取以外科手术(主要包括肝脏局部切除和肝移植)为主,放化疗为辅的综合治疗策略。然而由于肝癌起病隐匿,早期诊断率低,接受化疗的患者大多为晚期或者已经出现了转移病灶。因此,肝癌病
目的 本研究的目的是探讨SET8 在肝癌及癌旁组织中的表达,通过体内体外实验明确SET8 在调控肝癌糖代谢方面的重要作用,通过分子生物学实验阐明SET8 调控肝癌糖代谢的具体分子机制,为寻找有效的肝癌治疗靶点提供理论及实践依据。方法 通过免疫组化检测肝癌及癌旁组织中SET8 的表达情况,对TCGA(The Cancer GenomeAtlas)数据库进行检索,运用生物信息学方法分析SET8 的mR

目的 胶质瘤是成人原发性脑肿瘤中最常见的恶性肿瘤,预后较差.大约80％的胶质瘤显示有丝分裂原激活酶(MAPK)通路的改变,MAPK 基因决定侵袭性或增殖性表型的选择.然而,目前靶向特异性MAPKs 的抑制剂对胶质瘤的治疗效果尚未见报道.ZDHHC17(zinci-finger DHHC-type containing 17)属于棕榈酰转移酶(PATs),是用来催化棕榈酸酯与其他蛋白底物的结合.这种
