SEARCHBreast Model IDSB_0029 (version 1)
Model Submission Date2015-01-13
Model TypeGEMM
Model Name MMTV-PyMT (FVB)
JAX Number 02374
DescriptionThese transgenic mice have the polyoma virus middle T antigen (PyVT) under control of the mouse mammary tumour virus (MMTV) promoter/enhancer. Females develop mammary tumours which often (strain dependent) metastasize to the lungs. Males develop mammary tumours with longer latency. Pulmonary metastases are observed in 80-94% of tumour-bearing female mice.

Therapy Control (PBS), 100ug/kg zoledronic acid, 2mg/kg doxorubicin or 100ug/kg zoledronic acid followed 24h later by zoledronic acid. All treatments were administered once per week for 6 weeks.
Genetic Studies-
Notes No metastases were detected in the lungs or bones of these mice. On histological analysis mice were found to have signs of pneumonia and the lungs are full of immune infiltrate.
