| abstractText | Almost 60 years ago, Foulds carefully described for the first time a particular type of mouse mammary tumor that appeared in the glands of pregnant females and disappeared shortly after delivery. Since then, the attention that researchers paid to the Mouse Mammary Tumor Virus (MMTV)-induced pregnancy-dependent tumors has not vanished through the years. This was because the information obtained from mice carrying MMTV variants that were able to induce pregnancy-dependent tumors was meaningful for studying different aspects of mammary tumor biology. In addition, mice infected with these viral variants provided some of the few chances to use fully hormone-dependent estrogen receptor positive breast cancer models in the mouse. In the analysis of the association between tumor morphology and behavior, the mechanisms underlying progression towards autonomy, the impact of different genes during cancer initiation and development, and the relevance of host genetic background for tumor incidence and hormone-dependence, mouse strains carrying these MMTV variants have been very important tools that could not have been replaced with any other available model. The goal of this article is to provide a succinct chronicle of the experiments and observations made in the MMTV-induced pregnancy-dependent models that most significantly contributed to the mouse mammary tumor biology field. In addition, the possibility to use these MMTV variants as alternative models for analyzing mammary tumor stem cells and pregnancy-associated breast cancer in women is discussed. |
