RUNX1 and acute lymphoblastic leukemia: These data revealed that the ETV6/RUNX1-positive ALL patient group had on average 3.2-fold higher EPOR expression, compared to the hyperdiploid (ETV6/RUNX1-negative) ALL patient group (p < 0.001); indicating a strong association between ETV6/RUNX1 and EPOR expression in B-cell progenitor cells from ALL patients.
