Molecular genetics of breast cancer, translational studies.
This lab investigates the molecular and genetic alterations that are important early in human breast carcinogenesis. Our overall goal is to identify the abnormalities characterizing early cancer development, even before the tissue is histologically fully malignant. We hypothesize that these genetic abnormalities are biologically meaningful and clinically relevant. In testing this hypothesis, we (and others) have shown that cancer-related abnormalities can be present in hyperplastic lesions and even in histologically normal epithelium. We study primary human tissues, and we ask questions and employ techniques suitable to that material, including laser capture microdissection, loss of heterozygosity and copy number alteration, mRNAand miRNA expression [measured by microarray and quantitative PCR], and immunohistochemistry. Since we attempt comprehensive genetic analyses of the data, the work is multidisciplinary, and collaborations with pathologists, geneticists, surgeons and bioinformaticians and biostatisticians are crucial. In addition, we have projects ongoing with organizations both inside and outside BUMC, including the Framingham Heart Study and the Nurses’ Health Study-Benign Breast Disease Substudy. Identifying and understanding the landscape of molecular and genetic abnormalities in premalignant and histologically normal tissue should generate novel markers of breast cancer risk, uncover mechanisms implicated early in cancer initiation and progression, and identify new targets for cancer prevention and treatment.
