Description: TEL-AML1 is a fusion protein created by the t(12;21) chromosomal translocation observed in 25% of childhood B-cell acute lymphoblastic leukaemias. To study the potential role of TEL-AML1 in the development of leukaemia, we generated TEL-AML1 transgenic mice in which the expression of TEL-AML1 and a co-expressed EGFP reporter is dependent on Cre recombinase activity. Global expression of TEL-AML1 using pCX-NLSCre induced embryonic lethality at E7.5. In mice with haematopoietic and endothelial expression of TEL-AML1 using Tie2-Cre, the contribution of TEL-AML1 expressing cells to the foetal liver became limited by embryonic day (E) 14.5 due to increased apoptosis. At 1 month of age, TEL-AML1/Tie2-Cre mice had normal haematopoietic systems with limited contribution of TEL-AML1 expressing cells. Between 5 months and 2 years of age, TEL-AML1/Tie2-Cre mice developed spontaneous haematopoietic disorders including T- and B-cell lymphomas and high-grade anaemia.
