The program continues its focus on the human oncogenic herpesvirus, Epstein-Barr Virus (EBV) and Kaposi Sarcoma-associated Herpesvirus (KSHV) to identify the critical mechanisms by which these agents induce cancer and deregulate cell growth. To identify the mechanisms responsible for the oncogenic properties of these agents, the projects will characterize the basic molecular properties of viral proteins and their interactions with cellular proteins. In Project 1, Dr. Jack Griffith will continue his studies of the HSV recombinase complex consisting of ICP8 and UL12, and will apply the imaging skills that he has developed to analyze the structure of EBV and KSHV proteins and the association of KSHV proteins with DNA. Project 2 continues the study by Dr, Joseph Pagano on a novel deubiquitinase, UCHL1, whose expression is induced by EBV. This project will characterize the properties of this protein and in collaboration with Drs. Raab-Traub and Dittmer, determine its anti-growth properties in the mouse models that they have developed in Projects 4 and 5. Dr. Damania in Project 3 will develop systems to determine how KSHV induces angiogenesis, cell survival and migration. Drs. Raab-Traub and Dittmer in Projects 4 and 5 will develop and characterize the pathways that are essential for transformation and oncogenesis in transgenic murine models. The effects of EBV and KSHV on cellular miRNAs in the transgenic cancers will also be determined in both projects. A new core is requested, the Virogenomics Core, that will provide gene expression array support for all 5 projects on this program, profiling of the cellular miRNAs, and bioinformatic services for expression arrays and ChlP-Seq approaches.
