Research
In the Ellisen Laboratory, scientists identify genetic abnormalities in tumor cells that are not present in normal tissues, study how the abnormalities influence the biology of cancer cells, and explore how their new discoveries can inform the selection of the most effective therapy for each patient. Key tumor cell pathways under investigation in the laboratory include p53, BRCA1/2, and mTOR. Dr. Ellisen is best known for his work on triple-negative breast cancer (TNBC), one of the most aggressive forms of the disease. His research has shown that a chemotherapy drug used to treat several other types of cancer - but rarely breast cancer - holds promise for TNBC patients. Dr. Ellisen now oversees clinical trials of this and many other promising new therapies in breast cancer.
