| Title |
G-MDSC_2 |
| Sample type |
RNA |
| |
|
| Source name |
granulocytic fraction of myeloid-derived suppressor cells (G-MDSC)
|
| Organism |
Mus musculus |
| Characteristics |
strain background: BALB/c
group: splenic neutrophils of tumor-bearing mice
control group: yes
replicates: yes
class: clonal
sample id: G-MDSC_2
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Gene expression was analyzed in neutrophils from 3 different populations – 7 isolated from bone marrow of naïve mice (NN), 4 isolated from spleens of tumor bearing mice (Granulocytic myeloid derived suppressor cells, G-MDSC), and 4 isolated from flank AB12 tumors (Tumor associated neutrophils, TAN). All neutrophil populations were defined as Ly6G+. Neutrophils were isolated following preparation of single cell suspension, using CD11b-Miltenni beads for enrichment, followed by flow-sorting of the Ly6G+ cells. RNA was processed as previously described and hybridized on Illumina Mouse Ref-8 v2 microarray chips.

| Data processing |
Array data were processed by Illumina’s BeadStudio software and expression levels exported for analysis. The gene-wise, median correlation of each array compared to all other arrays was computed to ensure that no outliers existed within the data. The expression levels were then quantile normalized using Matlab software (2010b) and non-informative probes (those with detection p-value >0.05 in all samples) were removed to reduce experimental noise. Ultimately, 16,322 probes were used in our analysis.
