1986年10月-1995年12月，北京医科大学基础医学研究所吴秉铨等从基因、表达和蛋白产物三个层次，探索了控制肿瘤转移的途径。一、基因与癌转移。从人肺裸鼠巨细胞癌（PG）系脱氧核糖核酸（DNA）转化活性片段分析，该片段可能为一未知片段；人肺腺癌PAa在裸小鼠体内淋巴结转移率
From October 1986 to December 1995, Wu Bingjun, from the Institute of Basic Medicine, Beijing Medical University, explored ways to control tumor metastasis from the three levels of genes, expression, and protein products. First, genes and cancer metastasis. From the analysis of the active fragments of the DNA of the giant cell carcinoma (PG) line of human lung nude mice, this fragment may be an unknown fragment; the metastatic rate of human lung adenocarcinoma PAa in nude mice
