肿瘤细胞分裂、分化的调控

正常动物细胞的增殖是一个可控的过程,而恶性肿瘤细胞则可不受控制地生长。多肽类生长因子、致癌基因和致癌蛋白关系的新发现有助于阐明这些过程。本文基于这些研完成果,提出了通过促进细胞生长和抑制细胞生长的两大类物质调控细胞增殖的假设。已有的实验结果初步证实假设的合理性,这预示着可设计一些实验来寻找未知的调控细胞增殖的物质。这一假设的提出,为治疗癌症提供了新途径。

CONTROL OF DIVIO N AND DIFFERENTION OF TUMOR CELLS

proliferaton of nomal animal cells is a controllable process. on the contrary. proliferaton of cancer cells can't be controlled. Recent discovery of polypeptide growth factors, oncongenes and oncongenic proteins is helpful for us to understand these procss. Based on these research results, hypothesis that the cell growth is regulated by cell growth stimulators and cell growth inhibitors was put forward in this paper. the known experimental results have proved the rationality of hypothesis, which predicates that we can design some experiments to look for some unknown controlling substances. At the same time, the hypothesis will prpbably provide us a new way to treat cancer.
