Cancer Research Interest
- Disease Site Focus: No Specific Disease Site
- Research Focus Area: Diagnosis/ Prognosis, Carcinogenesis
- Type of Research: Basic
- Research Interest Statement: The following is the Relevance Statement from my R35 grant: A major focus of the project is DNA replication, a fundamental event that is required in all life forms, and its disruption can lead to several forms of disease, including cancer. The central engine of the replication machinery is the hexameric MCM complex that unwinds DNA at the replication fork once the tightly regulated replication process begins. MCMs and the kinases that activate them are logical, promising targets for anti-cancer therapies. A second focus of the project is the human RNA helicase DDX3X, which is associated with several human diseases, including HIV, HCV, and the brain cancer medulloblastoma. Mutation of this gene has been linked to medulloblastoma by genetic sequencing studies.
