Studying Biomarker Expression in Samples From Patients With Down Syndrome and Acute Myeloid Leukemia or Other Transient Myeloproliferative Disorder
Recruitment status was Active, not recruiting
RATIONALE: Studying samples of blood, tissue, and bone marrow from patients with cancer in the laboratory may help doctors learn about changes that occur in RNA and identify biomarkers related to cancer.
PURPOSE: This research trial studies RNA samples from patients with Down syndrome and acute myeloid leukemia or other transient myeloproliferative disorder.
Genetic: RNA analysis
Genetic: reverse transcriptase-polymerase chain reaction
Other: laboratory biomarker analysis
|Official Title:||Analysis of MicroRNA Expression in Down Syndrome Acute Myeloid Leukemia and the Transient Myeloproliferative Disorder|
- Gene expression levels between DS AMKL and non-DS AMKL patients [ Designated as safety issue: No ]
|Study Start Date:||February 2012|
|Estimated Primary Completion Date:||March 2012 (Final data collection date for primary outcome measure)|
- To compare miRNA expression in distinctive diagnostic groups: transient myeloproliferative disorder (TMD), Down syndrome (DS) acute megakaryocytic leukemia (AMkL), non-DS AMkL, and in remission DS samples (representing germline, non-malignant samples).
OUTLINE: Archived RNA samples are analyzed for mature micro (mi)RNA expression by real-time RT-PCR. Results are then compared with miRNA expression of non-Down syndrome patients with acute megakaryocytic leukemia.
