title: [Plasmid pSVc-myc-1 induces gene mutations and chromosome aberrations in cultured Chinese hamster cells].
abstract: The induction of mutations to 6-thioguanine-resistance and chromosome aberrations by the plasmid pSVc-myc-1, carrying the activated cellular oncogene c-myc, isolated from a mouse plasmocytoma was studied in a cultured Chinese hamster cell line. The yield of HPRT- mutants and chromosome aberrations increased 1.6 times on the average after pSVc-myc-1 treatment. The mutagenic activity of pSVc-myc-1 was statistically significant. The role of mutagenic effects of activated cellular oncogenes in malignant transformations is discussed.
