Transcriptional Alterations During Mammary Tumor Progression In Mice And Humans, Karen Fancher

Electronic Theses and Dissertations

Family history, reproductive factors, hormonal exposures, and subjective immunihistochemical evaluations of in situ lesions, and to a lesser extent age, remain the best clinical predictors of an individual's risk of developing breast cancer. Identification of early markers predictive of impending invasive breast cancer from in situ carcinoma is a long-term goal. The latent mammary cancer transgenic mouse model of human breast cancer, C57BL/6JTg(WapTag)1Knw (Waptag1), develops characteristic stages of tumorigenesis in a highly predictable manner: atypical hyperplasia advances to ductal carcinoma in situ (DCIS), which progresses to papillary adenocarcinomas and/or solid, invasive tumors. Microarray analyses of whole mammary glands and tumors …
