The transcription factor T-helper-inducing POZ/Krueppel-like factor (ThPOK, encoded by the Zbtb7b gene) plays widespread and critical roles in T-cell development, particularly as the master regulator of CD4 commitment. Here we show that mice expressing a constitutive T-cell–specific ThPOK transgene (ThPOKconst mice) develop thymic lymphomas. These tumors resemble human T-cell acute lymphoblastic leukemia (T-ALL), in that they predominantly exhibit activating Notch1 mutations. Lymphomagenesis is prevented if thymocyte development is arrested at the DN3 stage by recombination-activating gene (RAG) deficiency, but restored by introduction of a T-cell receptor (TCR) transgene or by a single injection of anti-αβTCR antibody into ThPOKconst RAG-deficient mice, which promotes development to the CD4+8+ (DP) stage. Hence, TCR signals and/or traversal of the DN (double negative) > DP (double positive) checkpoint are required for ThPOK-mediated lymphomagenesis. These results demonstrate a novel link between ThPOK, TCR signaling, and lymphomagenesis. Finally, we present evidence that ectopic ThPOK expression gives rise to a preleukemic and self-perpetuating DN4 lymphoma precursor population. Our results collectively define a novel role for ThPOK as an oncogene and precisely map the stage in thymopoiesis susceptible to ThPOK-dependent tumor initiation.

Two dominant lineages of T cells (αβ and γδ T cells) are highly distinct in function and anatomical location yet share a common precursor within the thymus. Exactly how one cell fate is decided over another remains unresolved. Melichar et al. present evidence that selection to the γδ T cell branch in the thymus is controlled by the transcription factor SOX13, which supports and possibly even initiates γδ T cell development while opposing differentiation of their αβ T cell brethren. The authors noted that SOX13 inhibited an important effector of the central T cell developmental signaling pathway mediated by the Wnt protein. H. J. Melichar, K. Narayan, S. D. Der, Y. Hiraoka, N. Gardiol, G. Jeannet, W. Held, C. A. Chambers, J. Kang, Regulation of γδ versus αβ T lymphocyte differentiation by the transcription factor SOX13. Science315, 230-233 (2007). [Abstract][Full Text]
