Notes |
Although expression of PU.1/SFPI1 in hematopoietic stem cells, myeloid progenitor cells and granulocytes is similar in mice homozygous for this mutation and for Sfpi1tm1.1Dgt ("UREdeltaneo"), which retains the PGK-neo cassette, mice with the present mutation develop acute myelocytic leukemia (AML) with a lower penetrance (29% vs. 97%) and a longer latency (6-12 months vs. 3-8 months) than do those with Sfpi1tm1.1Dgt. Mice with the present mutation often die of T cell lymphoma before the time of onset of AML. (J:106789;J:90331) The phenotypic difference may be due to genetic background differences, as Sfpi1tm1.1Dgt was analyzed on a ~50% BALB/c and the present mutation on a greater than 50% 129/Sv background.
