An in-vivo Screen for the Identification of Leukemia-Promoting Factors

Objective

The proposed research aims to identify and characterize factors conferring leukemic properties to hematopoietic cells. This screen will be based upon a murine leukemia model I have developed in my time at the Salk Institute (La Jolla, CA) these mice express a fusion of RARalpha with three FKBP12 Rapamycin-regulated dimerization domains” FKBP12 F36M (F3-RARa). These F3-RARa TG mice, though healthy, exhibit a “preleukemic” state that is more accessible to transformation by cellular factors, such as activated cytokine receptors. (Sternsdorf et al, 2006). At low frequency, these mice spontaneously develop myeloid leukemia with APL features. From these leukemias I want to identify leukemogenic factors. Freshly expanded Leukemia cells will be used to generate a retroviral cDNA library. Initially, I will use this library to transduce non-transplantable murine cell lines and test, which factors convey transplantability. In the following, I will transduce /transplant pre-leukemic bone marrow from younger F3-RARa mice. This should lead to leukemias, which will be tested, isolated by cell sorting, according to presence of viral integrate (GFP). Leukemias will be FACS-isolated by phenotype (GFP, Surface markers). The integrated retroviral vectors will be isolated by PCR. The goal of this analysis is to identify and characterize novel cellular factors, involved in the process of leukemia development. This will enable me to identify novel potential targets for therapy. I am an experienced scientist in the earlier part of my career: after spending nine years in the US, I am returning to the European Union. A Heisenberg Fellowship (Germany) made this possible. This fellowship, though prestigious, covers only a small amount of funding besides my salary. Therefore I consider the IRG a critical component of funding in this critical time of my career and the successful transfer of my knowledge to the hosting lab in Hamburg.
