Comment[ArrayExpressAccession] E-GEOD-51908 MAGE-TAB Version 1.1 Public Release Date 2013-10-31 Investigation Title miRNA expression data from normal and Malignant hematopoietic cells Comment[Submitted Name] miRNA expression data from normal and Malignant hematopoietic cells Experiment Description This data was used to identify miRNA signatures that can be used to calssify specific leukemia types including AML, precursor B ALL, precursor T ALL, and normal hematopoietic progenitor and mature populations This data was used to identify miRNA signatures that can be used to calssify specific leukemia types including AML, precursor B ALL, precursor T ALL, and normal hematopoietic progenitor and mature populations AML cell lines and patient samples, B ALL cell lines and Patient samplest, T ALL cell lines and patient samples, norma B cells, normal granulocytes, normal monocytes, normal T cells and normal CD34+ cells were used for RNA extraction and hybridization on Affymetrix microarrays. All the AML, B ALL, T ALL cell lines were cultured in vitro under appropriate culture conditons and harvested in their log phase growth for RNA extraction. AML, B ALL, and T ALL patient samples were collected...(I assume these are the PBMCs from eitehr peripheral blood or bone marrow from patients, please confirm). Normal B cells, granulocytes, monocytes, and T cells were purified from human peripheral blood of normal healthy donors.

Biotin labled RNA was hybridized for 16 hr at 45C on GeneChip miRNA 2.0 array. GeneChips were washed and stained in the Affymetrix Fluidics Station 450. N/A All the leukemia cell lines were culture in vitro under appropriate cell cutlure conditions according to the supplier recommondataion. Normal mature hematopoietic cells were purifed from normal healthy donor peripheral blood using Ficoll gradiant centrifugation followed by FACS sorting. Cell were lysed in Trizol and total RNA was purifed using miRNAeasy kit according to the manufacturer's instructions. GeneChips were scanned using Genechip Scanner 3000 and software AffyMetrix Genechip Command Console .
