Mouse cells transformed by the retroviral oncogene v-Ki- ras are significantly more sensitive to the toxic effects of 1mM ouabain than are their nontransformed counterparts. We have extended these findings to a human cell line (HOS). HOS cells (ATCC CRL 1543) are relatively resistant to treatment with 1 microM ouabain while KHOS cells (transformed by Kirsten murine sarcoma virus) are extremely sensitive. Two flat revertant cell lines isolated from the KHOS line and lacking the v- ras gene sequences are resistant to ouabain. This effect may be observed morphologically and can also be demonstrated by dye exclusion and plating efficiency tests. In addition, the toxic effects of ouabain may be rapidly and efficiently quantitated in a 51Cr-release assay. This differential lethality may be used to enrich the proportion of non-transformed revertants in populations of mutagen-treated transformed cells.
