Mammary tumor virus DNA as a marker for genotypic variance within hormone-responsive GR mouse mammary tumors.


Mammary tumors of GR mice acquire extra mammary tumor virus (MMTV) DNA information within their DNA during tumor growth and development. These extra MMTV genes have been used by us as genotypic markers to investigate the heterogeneity of GR mammary tumors and their loss of hormone dependence during serial transplantation. Our studies reveal that the various… (More)
