PAX5 and acute lymphoblastic leukemia: We examined leukemic cell populations from B-ALL (n = 2) and T-ALL (n = 8) from ETV6-ETV6–RUNX1 + Sca1-Cre mice, B-ALL (n = 2) from Sca1-ETV6-RUNX1 + Kdm5cf/wt + Sca1-Cre mice (n = 2), B-ALL (n = 3) from Sca1-ETV6-RUNX1 + Pax5-het mice, and B-ALL (n = 4) from Pax5-het mice (Martin-Lorenzo et al., 2015).
