title: Development of transformed phenotype induced by a human ras oncogene is inhibited by interferon.
abstract: Mouse IFN inhibited the development of transformed foci in NIH 3T3 cultures transfected with the viral Ha-MuSV(ras) and Mo-MuSV(mos) oncogenes, or with the human bladder carcinoma ras EJ/T24 DNA. IFN treatment five or seven days after transfection was still effective in inhibiting the oncogenic transformation, but did not inhibit significantly the biochemical transformation induced by pSV2-neo or Ecogpt DNA, so that inhibition of ras-induced transformation was not a result of a general effect on the transfection process. Treatment with IFN did not alter the expression of ras EJ/T24 DNA after the transformed phenotype had been established.
