Mammary Transcriptome in Mice After Estrogen Signaling Reduction

These researchers are evaluating the precancerous mammary transcriptome in mice that have received the estrogen modulator tamoxifen as a cancer preventive. These mice are genetically engineered to overexpress an oncogene in the mammary gland, undergo tumorigenesis with a high degree of repeatability, and demonstrate a significant delay in tumor latency and multiplicity when estrogen signaling is abrogated during the precancerous period. The overall goal is to identify a gene expression signature that is predictive of tamoxifen sensitivity and thereby uncover genes that are targets of estrogen receptor signaling.
