摘要: In order to know the involvement of multiple gene alterations in pathogenesis human lung cancer, we examined genes K-, H-ras (codons 12, 13, 61), p53(exons 5–9) and retinoblastoma susceptibility (RB)(exons 20–22) using polymerase chain reaction/single-strand conformation polymorphism method 32 cancer cell lines (5 squamous-cell carcinomas, 10 adenocarcinomas, 3 large-cell 14 small-cell carcinomas). 18 non-small-cell lines, were found 4 for K-ras (22%), none (0%), p53 (22%) RB (0%) gene. (SCLC) no or but 6 (43%) (21%) Coincident abnormalities p53, not any those only 2 SCLC lines. No association was observed between these three N-myc amplification. Although above may be involved some extent more factors are required its development.
