| Title |
MLL-rearranged infant ALL in vitro sensitive to prednisolone 2 |
| Sample type |
RNA |
| |
|
| Source name |
Primary infant ALL cells at diagnosis (untreated) (>90% blasts)
|
| Organism |
Homo sapiens |
| Characteristics |
disease state: Precursor B-cell acute lymphoblastic leukemia (ALL)
cell type: Primary infant ALL cells at diagnosis (untreated) (>90% blasts)
genotype: MLL-rearranged
age: < 1 year of age
prednisolone sensitivity: sensitive
|
| Treatment protocol |
Primary ALL samples were obtained at diagnosis (before treatment) and processed within 24 hours after sampling. All samples contained >90% leukemic blasts.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted form leukemic cells using TRIzol reagent (Invitrogen) according to the manufacturer's protocol
|
| Label |
biotin
|
| Label protocol |
Biotinylated cRNA were prepared according to the standard Affymetrix protocol from 6 ug total RNA (Expression Analysis Technical Manual, 2001, Affymetrix).
|
| |
|
| Hybridization protocol |
Fragmented cRNA was hybridized to Affymetrix HU133plus 2.0 microarrays. GeneChips were washed and stained in the Affymetrix Fluidics Station 400.
|
| Scan protocol |
GeneChips were scanned using the Hewlett-Packard GeneArray Scanner G2500A.
|
| Description |
sens_2
Gene expression profiling data (HU133plus2.0) MLL-rearranged infant ALL cels
|
| Data processing |
The CEL files represent the raw (unscaled; scaling factor = 1) gene expression data. Raw (unscaled) array data was collectively normalized using variance-stabilizing normalization (VSN), performed in the statistical environment R (version 2.10.1) using Bioconductor packages.
