    Myelodysplastic syndromes (MDS) are the most common hematological malignancy, affecting approximately 20,000 people annually in the U.S.

  • 2

    Silenced expression of the CDKN2B (p15INK4b) gene is found in 60–80% of MDS and leukemia cases, correlating with poor prognosis.

    Loss of p15INK4b expression skews hematopoietic progenitor differentiation towards granulocyte–macrophage progenitors.

  • 4

    p15INK4b does not affect cell proliferation or apoptosis but plays a specific role in the differentiation of blood progenitors.

  • 5

    The study utilizes various mouse models and cell lines to investigate the role of p15INK4b in hematopoietic progenitor cell fate.
