Description
This dataset contains collected RNASeq data of 552 samples from the GOYA clinical trial. Overall design: The GOYA trial tested the efficacy of Gazyva (GA101) compared with Rituxan (Rituximab) in first line, untreated DLBCL patients. Patients were randomized 1:1 to either G or R combined with a CHOP chemotherapy backbone. Tumor samples were collected at baseline, RNA was isolated using RNA-Access, and RNASeq was run with TruSeq (Illumina) RNASeq.

Description
The tumor suppressor p53 plays a crucial role in cellular growth control inducing a plethora of cellular response pathways. The molecular mechanisms that discriminate between the distinct p53-responses towards different stress treatments have remained largely elusive. Here, we have analyzed the p53-regulated pathways induced by two chemotherapeutical treatments, Actinomycin D inducing growth arrest and Etoposide resulting in apoptosis. We found that the genome-wide p53-binding patterns are almost identical upon both treatments notwithstanding transcriptional differences that we observed in genome-wide transcriptome analysis. To assess the role of post-translational modifications in target gene choice and activation we investigated the extent of phosphorylation of Serine 46 of p53 bound to DNA (p53-pS46), a modification that has been linked to apoptosis-pathways, and the extent of phosphorylation of Serine 15 (p53-pS15), a general p53-activation mark. Interestingly, the overall extent of S46 phosphorylation of p53 bound to DNA is considerably higher in cells directed towards apoptosis while the degree of phosphorylation at S15 of DNA bound p53 remains highly similar upon both treatments. Moreover, our data suggest that, following different chemotherapeutical treatments, the extent of chromatin-associated p53 phosphorylated at S46 but not at pS15 is higher on certain apoptosis related target genes, including the BAX and PUMA genes. These data provide evidence that cell fate decisions are not made primarily on the level of general p53 DNA-binding, but possibly through post-translational modifications of chromatin bound p53.

Description
Hereditary sensory and autonomic neuropathy type I (HSAN-I) is neurological disorder characterized by distal sensory neuron dysfunction, frequent infections, and ulcerative mutilations. It remains unknown if HSAN-I directly dampens protective immunity. Here we report that HSAN-I-causing mutations of serine palmitoyltransferase long chain base subunit 2 (SPTLC2) affect human T cell responses. T cell antigenic stimulation and inflammation induce SPTLC2 expression. Murine T cell-specific ablation of Sptlc2 fundamentally impairs antiviral T cell survival and effector function. Mechanistically, SPTLC2-deficiency reduces sphingolipid biosynthetic flux and causes a prolonged activation of the mechanistic target of rapamycin complex 1 (mTORC1), endoplasmic reticulum (ER) stress and CD8+ T cell death. Antiviral CD8+ T cell responses are restored by supplementing sphingolipids and pharmacologically inhibiting ER stress-induced cell death. Our study reveals that SPTLC2 underpins protective adaptive immunity by translating extracellular stimuli into intracellular anabolic signals and reducing cellular stress to maintain metabolic reprogramming sustainability Overall design: Triplicates of each group were used for RNA-seq. Four groups were studied: Wild-type and SPTLC2-deficient CD8+ T cells, harvested from either naïve mice (D0) or mice infected with LCMV Armstrong 8 days earlier (D8).

Description
This dataset encompassing the profiles of 150 lung cancer tumors was developed to serve as test dataset in the SBV IMPROVER Diagnostic Signature Challenge (sbvimprover.com). The aim of this subchallenge was to verify that it is possible to extract a robust diagnostic signature from gene expression data that can identify stages of different types of lung cancer. Participants were asked to develop and submit a classifier that can stratify lung cancer patients in one of four groups Stage 1 of Adenocarcinoma (AC Stage 1), Stage 2 of Adenocarcinoma (AC Stage 2), Stage 1 of Squamous cell carcinoma (SCC Stage 1) or Stage 2 of Squamous cell carcinoma (SCC Stage 2). The classifier could be built by using any publicly available gene expression data with related histopathological information and was tested on the independent dataset described here.

Description
Renal hypoxia is widespread in acute kidney injury (AKI) of various aetiologies. Hypoxia adaptation, conferred through the hypoxia-inducible factor (HIF), appears to be insufficient. Here we show that HIF activation in renal tubules through Pax8-rtTA-based inducible knockout of von Hippel-Lindau protein (VHL-KO) protects from rhabdomyolysis-induced AKI. In this model, histological observations indicate that injury mainly affects proximal convoluted tubules, with 5% necrosis at d1 and 40% necrosis at d2. HIF-1alpha up-regulation in distal tubules reflects renal hypoxia. However, lack of HIF in proximal tubules suggests insufficient adaptation by HIF.
