TAL1 and acute lymphoblastic leukemia: We also analyzed publicly-available gene expression data from two transgenic mouse models of T-ALL driven by different oncogenes which arrest at different T cell development stages, the Idh2R140Q/NUP98-HOXD13 (Idh2R140Q/NHD13) and SCL-LMO1 models [33], and gene expression data from pediatric T-LBL patient samples [34].
