| Extraction protocol |
GEP of human T-PLL cells. Sample preparation: PBMCs isolated from T-PLL patients (>95% purity of T-cells) and CD3+ T-cells isolated from PB of healthy donors (see paragraph 2 for detailed descriptions on cell purification) were submitted to RNA isolation using the mirVana kit (Invitrogen). GEP analyses were conducted using Illumina HumanHT‑12 v4 BeadChip arrays according to manufacturer’s instructions.

| Data processing |
Bioinformatics: We used the Illumina proprietary software GenomeStudio v1 to background-correct and to initially annotate the probes of the HumanHT-12 v4 Expression BeadChip. We filtered samples and genes by detection p-values and fluorescence intensities for at least 2/3 hits (p<0.05) to reduce false calls. Batch-effects were corrected by the ComBat method which uses an empiric Bayesian model framework. For literature references to bioinformatics methods and algorithms see Supplementary Table2). Since the official Illumina HumanHT-12 v4 Expression BeadChip annotation is outdated, we used the data mining tool biomaRt, version 75 of the Ensembl data base with R, version 3.1.0, and Bioconductor, version 2.10.
T-PLLs (n=70) and normal controls (CD3+ T-cells from 10 healthy donors) were grouped and tested separately for differential expression using the Student’s t-test on log-transformed fluorescence values (normally distributed). Fold-changes (fc) were calculated on the fluorescence values without logarithmic transformation. False discovery rates (FDRs) were calculated using the R package “qvalue”. Hierarchical clustering was carried out using the R package gplots, version 2.15.0 (distance function: euclidean; clustering: complete linkage).
