The hypothesis of an endogenous mammary tumor virus seems to be substantiated in this paper by: transfer of genetic information for an MTV in vitro by GR sperm cells; segregation of MTV-P and MTV-L markers in the test cross of the F/sub 1/ hybrid between C3Hf, producing MTV-L, and GR, releasing MTV-P; induction of MTV antigens by BrdU in cultures of kidneys from various mouse strains; and induction of MTV-O in BALB/c mice by lethal doses of radiation. The picture that emerges is that different genetic systems control the expression of endogenous mammary tumor viruses. There are those which seem to affect only that germinal provirus with which they are genetically linked, while others have an influence on other germinal proviruses as well as somatic proviruses. Further studies on the genetic regulation of the expression of the germinal MTV proviruses are in progress.
