Biomarkers in Samples of Bone Marrow From Patients With Acute Myeloid Leukemia

Completed
Conditions
Leukemia
Registration Number
NCT01290107
Lead Sponsor
Children's Oncology Group
Brief Summary

RATIONALE: Studying samples of bone marrow 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 looking at bone marrow samples from patients with acute myeloid leukemia.

Detailed Description

OBJECTIVES:

* To successfully transplant human acute myeloid leukemia (AML) cells into immunocompromised mice for the purpose of expansion of the cells.

* To harvest the cells and use chromatin immunoprecipitation (ChIP) methods to identify the locations of the protein complexes on the genome.

* To study the interactions of the Super Elongation Complex (SEC) and Dot1 Complex (DotCom) complexes in human leukemia samples.

* To compare the genomic targets of the complexes formed by MLL-ENL chimeras to non-MLL-rearranged leukemia samples to normal controls.

OUTLINE: Cryopreserved cells are implanted into NOD SCID gamma mice, expanded, harvested, and studied by chromatin immunoprecipitation (ChIP) methods (using antibodies to ENL, Af9, and AF10). Results are then analyzed by PCR, DNA sequencing, and/or microarray analysis.
