Study on the targeted therapy for colorectal cancer in vivo with CD-TK driven by CEA promoter

Abstract

研究背景 大肠癌是严重威胁人类健康的常见恶性肿瘤之一,目前在我国大城市已占恶性肿瘤发病率的第三位。尽管随着疾病的早期发现、手术方案的改进以及新的化疗药物的应用,患者的中位生存期较前有了很大的提高,但要达到长期无瘤生存还是很大的难题。因此,寻求新的有效的治疗手段成为目前亟需解决的问题。随着分子生物学和基因工程技术的不断发展,肿瘤的自杀基因疗法成为当今的研究热点。目前,CD-TK双自杀基因在相关的研究报道中初步显示了较好的抗肿瘤疗效,而自杀基因治疗的关键因素在于有高效的转移载体和高活性靶向转录的启动子所驱动的目的基因,鉴于绝大部分大肠癌细胞中都有CEA过度表达,因此已有相关的体外研究结果显示了由...Background: Colorectal cancer is one of the most common malignant tumor which severely threaten the human’s health. Present in our large cities it’s incidence rate in malignant tumor has become the third place.
