Current Research

Much of our research focuses on three projects centered around transcription factor NF-kB. In one project, we seek to understand the cellular and molecular mechanisms by which altered NF-kB activity contributes to a variety of human cancers, especially lymphoid cell cancers. For example, we have found that many human B-cell lymphomas have chronically high levels of nuclear NF-kB activity that is required for their growth and survival. More recently, we have also been investigating the role of NF-kB co-activator proteins called HATs (histone acectyltransferases) in human B-cell lymphoma.

In collaborative studies with Drs. John Porco, Adrian Whitty, and Karen Allen in the Chemistry Department at BU, we are characterizing natural and synthetic inhibitors of NF-kB signaling. Many of these inhibitors are derivatives of natural products, and may have anti-cancer or anti-inflammatory activities. In this project, we are also characterizing the structure and function of a protein called NEMO, which is an upstream adaptor protein for the NF-kB pathway and is mutated in certain human immunodeficiencies.
Finally, we are studying the evolutionary origins of the NF-kB pathway by characterizing NF-kB genes and proteins in simple marine organisms, such as the sea anemone Nematostella vectensis. This research may have relevance to the mechanisms by which simple marine organisms deal with the environmental stress that is currently impacting sensitive marine ecosystems. These studies are being carried out in collaboration with Drs. Les Kaufman, John Finnerty and Trevor Siggers (Biology Department, Boston University).
