RAG2 and leukemia: To further assess whether the E::R;pax5mut zebrafish leukemias better resembled B- or T-lymphoblastic leukemias, we downloaded publicly available transcriptomic data from the rag2-hMYC-driven and rag2-mMyc-driven zebrafish leukemia models, both yielding a mixture of B-ALL, biphenotypic ALL and T-ALL leukemias, as well as from a previous rag2-TLX1-driven T-ALL zebrafish model [49,50,51].
