为了解多基因改变在肺癌发病中的作用,我们检测了K-、H-ras基因,(密码子12,13,61),p53(外显子5-9)和视网膜母细胞瘤易感基因(RB)应用聚合酶链反应/单链构象多态性方法对32株人肺癌细胞系的20-22号外显子进行了分析(5例鳞状细胞癌,10例腺癌,3例大细胞癌,14例小细胞癌)。在18个非小细胞肺癌细胞系中,K-ras基因4个(22%),H-ras基因0个(0%),p53基因4个(22%),RB基因0个(0%)。在14个小细胞肺癌(SCLC)细胞系中,未发现K-ras(0%)或H-ras(0%)基因改变,但发现6个p53(43%)和3个RB(21%)基因改变。未发现K-ras和p53基因或K-ras和RB基因同时异常,仅2株SCLC中发现p53和RB基因同时异常。这三个基因的改变和N-myc扩增之间没有观察到关联。虽然上述三个基因可能在一定程度上参与了肺癌的发病,但其发生发展还需要更多的因素。
In order to know the involvement of multiple gene alterations in the pathogenesis of human lung cancer, we examined the genes of K-, H-ras (codons 12, 13, 61), p53(exons 5–9) and the retinoblastoma susceptibility gene (RB)(exons 20–22) using the polymerase chain reaction/single-strand conformation polymorphism method in 32 human lung cancer cell lines (5 squamous-cell carcinomas, 10 adenocarcinomas, 3 large-cell carcinomas, 14 small-cell carcinomas). In 18 non-small-cell lung cancer lines, gene alterations were found in 4 for K-ras (22%), none for H-ras (0%), 4 for p53 (22%) and none for the RB (0%) gene. In 14 small-cell lung cancer (SCLC) lines, no gene alterations were found in K-ras (0%), or H-ras (0%), but 6 were found for p53 (43%) and 3 for the RB (21%) gene. Coincident abnormalities of K-ras and p53, or K-ras and RB genes were not found in any cell lines, and those of the p53 and RB genes were found in only 2 SCLC lines. No association was observed between these three gene alterations and N-myc amplification. Although the above three genes may be involved to some extent in the pathogenesis of lung cancer, more factors are required for its development.
