Reversal of antiprogestin resistance and progesterone receptor isoform ratio in acquired resistant mammary carcinomas

To explore mechanisms related to hormone resistance, three resistant variants of the MPA mouse breast cancer tumor model with low levels of progesterone receptor (PR) isoform A (PR-A)/high PR-B expression were developed by prolonged selective pressure with antiprogestins. The resistant phenotype of...
