Abstract excerpt
To elucidate the mechanisms by which tumor cells escape the immune defenses of the normal host, we have isolated progressor tumor variants from a regressor tumor cell line by transfection with an activated Ha-ras oncogene. We previously found that the progressor phenotype of Ha-ras-induced variants was not due to loss of tumor-specific or major histocompatibility complex antigens. In this study, we investigated...
