Jessie A. Brown, PhD

Dr. Brown studies acute lymphoblastic leukemia (ALL), an aggressive leukemia and one of the most common malignancies in children and adolescents. Despite significant progress, relapse is associated with high rates of drug resistance and poor prognosis. As a result, relapsed ALL is the leading cause of cancer-related death in children. Dr. Brown will use large-scale genetic (DNA) and transcriptomic (RNA) data and leukemia animal models to dissect how a small number of ALL cells are able to escape the cytotoxic effects of chemotherapy. These cells then undergo genetic and epigenetic changes that allow them to generate resistance to chemotherapy and proliferate, causing relapse of this devastating childhood disease. Understanding this process may lead to novel therapeutic approaches for relapsed ALL.
