|Study Start Date:||February 2013|
|Estimated Primary Completion Date:||January 2100 (Final data collection date for primary outcome measure)|
- Determine the extent and prognostic implications of variable s-SHIP expression and SHIP gene mutations in pediatric patients with acute myeloid leukemia.
- Determine the effects of aberrant s-SHIP expression on the PI3K/Akt pathway in these patients via electrochemiluminescence and phosphospecific flow cytometry assays.
OUTLINE: RNA samples are analyzed for variable s-SHIP expression and are screened for SHIP mutations. Cryopreserved cells (with known high- or low-s-SHIP expression) are analyzed for the levels of various components of the PI3K/Akt pathway via electrochemiluminescence and phosphospecific flow cytometry.
