肿瘤从分子生物学及遗传学的角度可以看成是一类基因或 DNA的疾病 ,是由某些染色体上的 DNA的损伤而使体细胞发生突变的结果。随着分子生物学技术的不断进步 ,胃癌的基因研究也取得较大的进展。胃癌的发生、发展涉及多种癌基因、抑癌基因及细胞周期调节基因变化的积累 ,以及基?
Tumor can be regarded as a kind of gene or DNA disease from molecular biology and genetics perspective. It is a result of mutation of somatic cells caused by DNA damage on some chromosomes. With the continuous progress of molecular biology, gene research of gastric cancer has made great progress. The occurrence and development of gastric cancer involve in the accumulation of many oncogenes, tumor suppressor genes and cell cycle regulated genes,
