Biomarkers in Tissue Samples From Young Patients With Acute Myeloid Leukemia
Recruitment status was Active, not recruiting
RATIONALE: Studying samples of tissue from patients with cancer the in laboratory may help doctors identify and learn more about biomarkers related to cancer.
PURPOSE: This research study is studying biomarkers in tissue samples from young patients with acute myeloid leukemia.
Genetic: DNA methylation analysis
Genetic: gene expression analysis
Genetic: microarray analysis
Genetic: reverse transcriptase-polymerase chain reaction
Other: laboratory biomarker analysis
|Official Title:||Promoter Methylation in MLL-Rearranged Childhood AML|
- Identification of differential patterns of promoter hypermethylation and gene expression in pairwise comparisons with other cohorts and normal controls [ Designated as safety issue: No ]
|Study Start Date:||November 2010|
|Estimated Primary Completion Date:||January 2011 (Final data collection date for primary outcome measure)|
- To determine whether the pattern of global and TSG-specific promoter CpG island hypermethylation and gene silencing that we have shown characterizes MLL-rearranged (MLL-r) infant bilineage ALL is also characteristic of other subsets of MLL-r leukemia.
OUTLINE: Previously collected cryopreserved cells from diagnosis are analyzed for promoter methylation via HELP arrays, gene expression arrays, and RT-qPCR.
PROJECTED ACCRUAL: A total of 32 samples (8 from each of 4 biologically defined cohorts) will be analyzed.
