The MPA mouse breast cancer model: evidence for a role of progesterone receptors in breast cancer [PDF]

open access: yes, 2009
More than 60% of all breast neoplasias are ductal carcinomas expressing estrogen (ER) and progesterone receptors (PR). In contrast, most of the spontaneous, chemically or MMTV induced tumors, as well as tumors arising in genetically modified mice do not ...
