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.

Further study details as provided by National Cancer Institute (NCI):

Primary Outcome Measures:
  • Successful transplantation of human acute myeloid leukemia (AML) cells into immunocompromised mice for the purpose of expansion of the cells [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Identification of the locations of the protein complexes [ Designated as safety issue: No ]
  • Interactions of the SEC and DotCom complexes in human leukemia samples [ Designated as safety issue: No ]

Estimated Enrollment: 9
Study Start Date: February 2011
Estimated Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Detailed Description:


  • 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.
