恶性肿瘤是严重威胁人类生命的疾病,虽有许多科学工作者从事肿瘤的病因、诊断和治疗等方面的研究,但至今仍未能阐明其发病机理,因而也未能找到彻底治疗的措施。 有关核酸和蛋白质大分子的结构与功能方面知识的增加,使研究工作者能从分子生物学的基础上对肿瘤的发生机理进行探讨。许多事实表明肿瘤发生的共同特点是基因表 Malignant tumors are serious diseases that threaten human life. Although many scientists work on the etiology, diagnosis and treatment of tumors, they have not yet elucidated the pathogenesis of tumors. Therefore, they failed to find a thorough treatment. The increased knowledge about the structure and function of nucleic acids and protein macromolecules allows researchers to explore the mechanisms of tumor development on the basis of molecular biology. Many facts show that the common feature of tumorigenesis is the gene list
