Transgenic models of lymphoid neoplasia and development of a pan-hematopoietic vector

Abstract

The pathways to lymphoid neoplasia have been explored in a number of transgenic models. Because B lymphoid malignancies often involve translocation of an oncogene (e.g. myc, bcl-2, cyclin D1) to an immunoglobulin locus, resulting in its deregulated expression, the consequences of oncogene overexpression in lymphocytes can be evaluated with transgenes driven by an immunoglobulin regulatory element, such as an enhancer from the IgH locus. Mice bearing such transgenes have provided insight into the preneoplastic state, including alterations in the control of cellular proliferation, differentiation or apoptosis. They have also allowed studies on oncogene cooperation in vivo and the modulating ef..
