Abstract Systems biology has experienced dramatic growth in the number, size, and complexity of computational models. To reproduce simulation results and reuse models, researchers must exchange unambiguous model descriptions. We review the latest edition of the Systems Biology Markup Language (SBML), a format designed for this purpose. A community...

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 expe...

Table S7. Associations between Drug Response and Molecular Data, Related to Figures 7 and S7 The predictive performance, data type and target pathway is shown for each association. The column “Corrected for ABCBs?” indicates whether the feature was predicted with the mean protein abundance of ABCB1 and ABCB11 regressed-out from drug response data.

ANOVA pvalues refer to any comparison between the WT, ARID1A, ARID2 and PBRM1 replicate groups. RNA-seq quantification and significance is shown only for the re...
Data
Table S1. Relative Protein Abundances in the COREAD Cell Lines, Related to Figures 1, 2, 3, 5, 6, and 7 Scaled protein quantification values for 50 colorectal cancer cell lines. Proteins affected by mutations or DNA copy number alterations are annotated by ANOVA p value and average log2fold-changes where applicable.

Assessing the impact of genomic alterations on protein networks is fundamental in identifying the mechanisms that shape cancer heterogeneity. We have used isobaric labeling to characterize the proteomic landscapes of 50 colorectal cancer cell lines and to decipher the functional consequences of somatic genomic variants. The robust quantification of...
Preprint
Assessing the extent to which genomic alterations compromise the integrity of the proteome is fundamental in identifying the mechanisms that shape cancer heterogeneity. We have used isobaric labelling and tribrid mass spectrometry to characterize the proteomic landscapes of 50 colorectal cancer cell lines and to decipher the relationships between g...

Systematic studies of cancer genomes have provided unprecedented insights into the molecular nature of cancer. Using this information to guide the development and application of therapies in the clinic is challenging. Here, we report how cancer-driven alterations identified in 11,289 tumors from 29 tissues (integrating somatic mutations, copy numbe...

Numerous pathway methods have been developed to quantify the signaling state of a cell from gene expression data, usually from the abundance of transcripts of pathway members, and are hence unable to take into account post-translational control of signal transduction. Gene expression signatures of pathway perturbations can capture this, but they ar...

BioModels (http://www.ebi.ac.uk/biomodels/) is a repository of mathematical models of biological processes. A large set of models is curated to verify both correspondence to the biological process that the model seeks to represent, and reproducibility of the simulation results as described in the corresponding peer-reviewed publication. Many models...

Horseradish peroxidases (HRPs) from Armoracia rusticana have long been utilized as reporters in various diagnostic assays and histochemical stainings. Regardless of their increasing importance in the field of life sciences and suggested uses in medical applications, chemical synthesis and other industrial applications, the HRP isoenzymes, their sub...

Systems biology projects and omics technologies have led to a growing number of biochemical pathway models and reconstructions. However, the majority of these models are still created de novo, based on literature mining and the manual processing of pathway data. To increase the efficiency of model creation, the Path2Models project has automatically...

... For simplicity, we refer to the pipeline as described in 19 as the CARNIVAL pipeline. Briefly, PROGENy is used to infer pathway activity from the log2 FC of the infected immature enterocytes 2 gene expression data 87 . Next, using the TF-TGs interactions (from DoRothEA) and the differential expression data from infected organoids, VIPER was used to score TF activity based on enriched regulon analysis 88 . ...
... In detail, the Illumina 450 k DNAm data from 48 purified immune-cells (6 × 8 cell-types) was derived from Reinius et al. [51]. From Iorio et al. [52] we obtained Illumina 450 k DNAm profiles for a total of 7 EAC cell-lines (ESO26, ESO51, FLO-1, KYAE-1, OACM5-1, OACP4C an SK-GT-4). For the squamous epithelial cells we first identified buccal swabs with over 95% purity, as determined with our HEpiDISH algorithm with the DNAm reference matrix defined above, and as applied to our large buccal swab 450 k DNAm dataset of 790 buccal swabs [32]. ...
... The combinatorial properties occurring among the alterations are then analyzed and used to define cost functions, for example, based on the tendency of a group of genes to be mutated in a mutually exclusive manner. On the basis of these cost functions, optimal sub-networks are identified and interpreted as novel cancer driver pathways [22][23][24] . However, at the moment there is no consensual method to rigorously define a mathematical metric for mutual exclusivity and compute its statistical significance, and a number of interpretations exist 22,23,[25][26][27] . ...
