摘要
癌症对于人类健康的威胁毋庸置疑.为了发现更有效的治疗方法,国内外专家学者一直将肿瘤的发生机制作为研究的重点和热点.众所周知,恶性肿瘤细胞的基本生物学行为,如增殖活性、凋亡能力等,都发生了很大的改变,而其原因都与细胞内发生的异常甲基化反应有关.以往的研究已经发现,肿瘤组织与正常组织中的DNA甲基化明显不同,有着广泛低甲基化伴局部高甲基化的特点.为明确异常甲基化反应在肿瘤发生、发展中的作用,本文特就肿瘤组织中发生的异常甲基化反应及其对细胞生长的影响作一综述.
The threat of cancer to human being＆#39; s health is definite.In order to find more effective cures,experts has always taking the mechanism of tumorigenesis as a research foucus and hot spot.As everyone knows,the basic biological behaviors of malignant cells have changed a lot,such as cell proliferation,apoptosis,and so on,and the causes are related to the aberrant methylation reaction occurred in these cells.Researchers have found out that DNA methylation in tumor tissues were obviously different from that in normal tissues,with the charateristics of extensive hypomethylation and localized hypermethylation.To identify the effect of abnormal methylation reaction in the evolution and progression of tumor,this article is aiming to overview those previously researches about the abnormal methylation reaction in tumor cell and its effect on cell growth.
