Research Abstract
Our laboratory is focused on understanding the chromatin remodeling
processes that establish the normal epigenetic landscape in developing tissue,
how it can be perturbed to promote carcinogenesis, and provide insight for the
development of new therapies. We are particularly interested in how the RB
pathway, which is altered in virtually every cancer, control epigenetic events
that control cell fate specification and differentiation in normal cells - aiming to
elucidate the relationship between cell differentiation and tumorigenesis in the
absence of the RB family. We are currently studying the role of chromatin
remodelers regulated by the RB pathway in the formation of retinal, bone, and
lung cancers. Our work will likely influence the development of new therapeutic
interventions for retinoblastoma, osteosarcoma, small cell lung cancer, and
other cancers with RB pathway inactivation.
