Runx1 regulates zebrafish neutrophil maturation via synergistic interaction with c-Myb

Neutrophils play an essential role in the innate immune defense system in vertebrates. During hematopoiesis, the full function of neutrophils involves maturation of granules and related enzymes. Yet, transcription regulators that promote neutrophil maturation remain largely undefined. Here, two hematopoiesis-defective zebrafish mutants, runx1w84x and c-mybhkz3, were used to investigate the in vivo roles of Runx1 in cooperation with c-Myb in...
