简要总结
RATIONALE: Studying samples of tissue from patients with cancer in the laboratory may help doctors learn more about cancer and development of drug resistance in patients.
PURPOSE: This research trial is studying proteins that may promote chemotherapy resistance in samples from patients with acute myeloid leukemia.
详细描述
OBJECTIVES:
- Investigate whether changes in prosurvival signaling occur by comparing activation of the signal transducer and activator of transcription-3 (Stat3) and Stat5 pathways in paired diagnostic and relapse samples.
- Investigate changes in leukemia cell responses to extrinsic cues from the environment change, using a bone marrow stromal-cell co-culture model of chemotherapy resistance.
OUTLINE: Cryopreserved samples are analyzed for Stat3 and Stat5 expression by flow cytometry and in vitro chemotherapy sensitivity.
