Abstract
AbstractTwelve cell lines isolated from patients with small cell lung cancer have been studied for amplification of the three characterised members of the myc proto‐oncogene family (c‐myc, N‐myc, and L‐myc) and for abnormalities of chromosome 3. Ten of these lines were being studied for the first time. Ten of the 12 small cell lung cancer cell lines had amplification of one member of the myc proto‐oncogene family. Amplification of c‐myc was observed in only one small cell lung line—a “morphological variant.” One “classic” small cell lung cancer line expressed c‐myc but had no obvious amplification of the gene. N‐myc and L‐myc were more commonly amplified than c‐myc. Chromosomal abnormalities (mainly deletions) in chromosome 3 were observed in all small cell lung carcinoma cell lines examined. When the small cell lung carcinoma lines were grouped according to “classic” or “variant” characteristics, it was found that the “classics” had deletions of the short arm of chromosome 3, whereas the “biochemical variants” had deletions of the long arm of chromosome 3. The extent of the deletions varied between cell lines. For the deletion in the short arm of chromosome 3 the minimum common region of overlap was assigned to bands 3p23–3p24.
