| Organism |
Homo sapiens |
| Characteristics |
patient: NB4
pdxs: M7
cell type: Tumor cells
|
| Growth protocol |
The tumor samples were subjected to mechanical and enzymatic dissociation using Tumor Dissociation Kit (Miltenyi Biotec). The dissociated tumor cells were suspended in DMEM/F12 medium supplemented with 1% penicillin-streptomycin, 2% B27 (Invitrogen), and 20ng/ml of human recombinant FGF and EGF (Peprotech). Adherent cells were cultured in DMEM (catalog no. Gibco) supplemented with 10% of FBS (PAN-Biotech) and 1% of penicillin-streptomycin (Gibco). Cells were maintained at 37°C in humidified, 5% CO2 chambers. Spheroid was grown in ultralow attachment plates (Corning).

| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted with miRCURY kit (Exiqon) using Lysis buffer + B-mercaptoethanol. For tumor samples, dissociation was performed following gentleMACS Dissociator kit instructions for soft tumors (Miltenyi Biotech).
Minimum 100 ng used for preparing sequencing libraries using the TruSeq mRNA stranded kit (Illumina) and sequencing was performed on a Hi-Seq Illumina Genome Analyzer (100 bp single-read).

| Data processing |
RNA-seq reads were mapped to the hg38 genome (only chromosomes 1 to 22, X, Y and M) using hisat2 (version 2.0.5) and the Ensembl gene annotations Homo sapiens GRCh38.87.
Read density tracks were generated using bedtools genomecov (version 2.29.0 option -split) for each genomic position and read counts were normalized to one million reads in the library and visualized using the IGV browser.
Raw read counts and RPKM values were calculated over gene exons using htseq-count (version 0.9.1). Differentially expressed genes were identified using DESeq2 (version 1.26.0) using the following thresholds: adjusted p-value <= 0.001 and fold change >= 2.
Gene ontology annotations were used to calculate the enrichment of biological processes and associated hypergeometric p-values of genes in each class compared to all genes.
