Strain Description: The promyelocytic leukemia gene PML was originally identified at the t(15;17) translocation of acute promyelocytic leukemia, which generates the oncogene PML-retinoic acid receptor ?. PML epitomises a subnuclear structure called PML nuclear body. PML controls cell growth and tumorigenesis. Although the incidence of spontaneous tumors in the Pml -/- cohort was not increased during the first year of life and Pml -/- are grossly normal, the role of PML in tumorigenesis and leukemogenesis has been firmly established. The progressive reduction of Pml gene dosage obtained by crossing PML-RARa transgenic mice with Pml -/- mice resulted in a dramatic increase in the incidence of leukemia and in an acceleration of leukemia onset (Rego et al., 2001). In additon, Pml -/- mice are highly susceptible to develop tumors in in-vivo models of chemical-induced carcinogenesis (Wang et al., 1998). Further, analysis of Pml -/- mice also demonstrated that PML exerts its tumor suppressive role at least in part by coordinating a number of proapoptotic responses of critical relevance both in the maintenance of cellular homeostasis in several organs including the bone marrow, as well as in the clearance of cells in response to stress/DNA damage (Wang et al., 1998).
