Illumina humanRef-8 v2.0 expression beadchip
Description
Transcriptome of HEK and B cells were analyzed by microarray and RNA-Seq parallely. Both platforms were then compared in terms of sensitivity. To assess whether values were a reliable indicator of gene activity, we correlated these values with hypophosphorylated RNA polymerase II (PolIIa) occupancy, used as a landmark of transcription initiation. For HEK, we identified PolIIa islands by chromatin immunoprecipitation and sequencing (ChIP-Seq).

Description
The oncogenic mechanisms and tumour biology underpinning Clear Cell Sarcoma of Kidney (CCSK), the second commonest paediatric renal malignancy, are poorly understood and currently therapy depends heavily on Doxorubicin with cardiotoxic side-effects. Previously, we characterised the balanced t(10;17)(q22;p13) chromosomal translocation, identified at that time as the only recurrent genetic aberration in CCSK. This translocation results in an in-frame fusion of the YWHAE (encoding 14-3-3e) and NUTM2 genes, with a somatic incidence of 12%. Clinico-pathological features of that cohort suggested that this aberration might be associated with higher stage and grade disease. Since no primary CCSK cell line exists, we generated various stably transfected cell lines containing doxycycline-inducible HA-tagged-YWHAE-NUTM2, in order to study the effect of expressing this transcript. 14-3-3e-NUTM2-expressing cells exhibited significantly greater cell migration compared to mock-treated controls. Gene and protein expression studies conducted in parallel on this model system suggested dysregulation of signalling pathways as a basis to the migration changes. Importantly, by blocking these signalling pathways using anti-EGFR, anti-IGF1R and anti-PDGFa neutralising antibodies, the migratory advantage conferred by transcript expression was abrogated. These results support 14-3-3e-NUTM2 expression as a contributor to CCSK tumorigenesis and provide avenues for the exploration of novel therapeutic approaches in CCSK.

Description
Aberrant cell signaling can cause cancer and other diseases and is a focal point of drug research. A common approach is to infer signaling activity of pathways from gene expression. However, mapping gene expression to pathway components disregards the effect of post-translational modifications, and downstream signatures represent very specific experimental conditions. Here we present PROGENy, a method that overcomes both limitations by leveraging a large compendium of publicly available perturbation experiments to yield a common core of Pathway RespOnsive GENes. Unlike existing methods, PROGENy can (i) recover the effect of known driver mutations, (ii) provide or improve strong markers for drug indications, and (iii) distinguish between oncogenic and tumor suppressor pathways for patient survival. Collectively, these results show that PROGENy accurately infers pathway activity from gene expression. Overall design: HEK293?RAF1:ER cells were treated with different stimuli (4OHT, Ly29002, TNFa, TGF1b, IFNg) for different periods of time (1h, 4h).
