RESUMO

In normal mouse mammary epithelium, insulin, cortisol, and prolactin are absolute requirements for mouse mammary tumor virus expression. Retinoic acid further increased mouse mammary tumor virus expression two- to threefold but only when triiodothyronine was also present; neither retinoic acid nor triiodothyronine alone had any effect.
