Vivian Bardwell, PhD

Research Interests:

The Bardwell laboratory is interested in the role of transcription factors
in cancer and development. Their work focuses on BCL6 and the DMRT
family of transcription factors. In appropriate expression of BCL6 protein
leads to the development of diffuse large cell lymphomas. They are
investigating the mechanisms of transcriptional repression used by the
BCL6 co-repressor, BCOR. The lab is also studying the role of BCOR
in the generation of lymphomas and in development, where it has multiple
important functions. Some DMRT proteins are important in testis development
and may play a role in the generation of cancer. They are investigating their
mechanisms of transcriptional regulation.
