Biomarkers in Samples From Patients With Down Syndrome and Acute Megakaryoblastic Leukemia
Development of Novel Therapeutics for AMKL

RATIONALE: Studying samples of blood or tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer.

PURPOSE: This research study is studying biomarkers in samples from patients with Down syndrome and acute megakaryoblastic leukemia.

OBJECTIVES:

  • Determine whether megakaryocyte differentiation agents comprising a Rho kinase inhibitor and a JAK3 inhibitor can lead to proliferation arrest, polyploidization, and terminal differentiation of blasts in specimens from patients with Down syndrome and acute megakaryoblastic leukemia.

OUTLINE: Cryopreserved specimens are cultured and treated in vivo (in mice) and in vitro with megakaryocytic differentiation agents comprising a Rho kinase inhibitor and a JAK3 inhibitor.
