Abstract

The primary goal of the proposed research is to understand the molecular genetic basis of the development of B-cell lymphomas in mice. The identification of new loci that are implicated in causing murine B Our specific aims are: 1) identify the nature of alterations of the genes caused by the retroviral integrations at Evi-3, 2) show that the normal cellular roles of genes at Evi-3 are consistent with their roles as proto-oncogenes when altered by the retroviral integrations, 3) identify the role of EVI3 in human disease, and 4) obtain additional B-cell lymphomas from the AKXD mice for protein and RNA studies, B-cell differentiation studies, and additional molecular tagging studies. We plan to use molecular and cellular approaches to study gene function. These approaches include additional cloning, sequencing, and gene expression analysis. We also propose to develop additional resources for studying Evi-3 and for cloning new genes associated with other common sites of retroviral integration by aging mice from the AKXD recombinant inbred strains, and preserving tumor cells for expansion. These tumors will be valuable resources for our lab, as well as for other labs studying hematopoietic tumors or B-cell development.
