Laura Pasqualucci, MD
Dr. Pasqualucci’s research interests focus on the molecular pathogenesis of B cell malignancies, with emphasis on its most common types, diffuse large B cell lymphoma (DLBCL) and follicular lymphoma (FL). The laboratory takes advantage of genomic profiling approaches and genetically modified mouse models to identify and functionally characterize the genetic lesions that are associated with these cancers, as a tool to better understand the mechanisms that are responsible for the initiation and maintenance of the tumor cell. The ultimate goal is to develop improved biomarkers and more effective treatment options for lymphoid malignancies.
Over the past decade, Dr Pasqualucci's work has led to the discovery of multiple genes that are recurrently disrupted by genetic lesions in lymphoma and play a critical role in both normal and transformed germinal center B cells. More recently, her group uncovered highly frequent mutations in genes that encode for epigenetic modifiers, including the methyltransfersase KMT2D and the acetyltransferases CREBBP and p300. These genes have emerged as central players in many different cancers, and were documented as tumor suppressors in lymphoma. This information is currently being exploited for the development of improved targeted therapeutic approaches in these diseases.
