Welcome to PrECISE


The PrECISE project is a pilot project that combines hypothesis-driven strategies with data-driven analysis in a novel mathematical and computational methodology for the integration of genomic, epigenetic, transcriptomic, proteomic, and clinical data with the goal of risk-stratifying patients and suggesting personalized therapeutic interventions. We have the following specific objectives:

  • Development of a comprehensive computational methodology:
  • To integrate publicly available multi-omics datasets, well-characterized multiple-biopsies cohorts, and literature-driven knowledge powered by the Watson cognitive computer, developed at IBM.


  • Characterization of intra-tumour heterogeneity:
  • We will apply PrECISE to prostate cancer molecular cohorts where multiple biopsies have been generated from each patient.


  • Suggestion of chemotherapy drugs and targeted therapies for each patient:
  • We will investigate molecular mechanisms, identify suitable intervention points for therapy and suggest personalized therapies based on patient’s clonal signatures, and we will validate our predictions in a panel of prostatic cell lines.


  • Development of PrECISE into deployable, easy to use software tool:
  • We will integrate the developed computational modules with the Watson cognitive technology developed at IBM in a user-friendly interface and make PrECISE accessible to the clinical research community.

Submitted:

WP1:

D1.1 "Final regulatory network inference"
This report describes graphical user interfaces developed for genomic and clinical data entry for PrECISE.

WP2:

D2.1 "Targeted ultra-deep sequencing of cancer-gene loci"
We set out to test our ability to infer mutations and their clonality using 10 castrate-resistant prostate cancer (CRPC) tumor biopsies. Conclusions from studying these biopsies informed methodology for selecting additional tumors for profiling by exome sequencing, for predicting mutations and exome sequencing, and allowed us to devise criteria for estimating mutation cellularity (a necessary step for inferring clonality in WP1). Clonality inference is a building block for prognostic-biomarker inference in WP3, and tumor classification in WP4.

D2.2 "Ultra-deep sequencing of prognostic biomarkers"
This report describes an effort to sequence prognostic biomarkers for prostate cancer. We designed a prognostically predictive biomarker panel that targets thirty-six commonly mutated predictive genes and used this panel to profile forty-two Castration Resistant Prostate Cancer (CRPC) patients.

WP3:

D3.1 "Computational pipeline to extract prior network information at the proteomic level"
This document gives an overview of the Omnipath database and its accompanying Python module Pypath. Omnipath gathers 54 resources, including 27 high-confidence literature curated signaling resources, providing and easy, unified and convenient entry point to much of the protein interaction knowledge available. Overall, Omnipath and Pypath greatly facilitate the integration and extraction of biological prior knowledge for analysis and model building, and they can be incorporated into wider data processing pipelines. Pypath and Omnipath are available here.

D3.2 "Network reconstruction algorithms for MS data"
As modern biological-data measurement technologies have been generating more and more high-dimensional data in recent years, data-driven protein–protein interaction (PPI) network reconstruction has garnered a lot of interest. MS time-course perturbation data is expected to be made available in the course of the PrECISE project. Our goal is to develop network reconstruction algorithms appropriate for this kind of data. This report introduces two approaches that have been the focus of work at TUDA towards network reconstruction from MS data.

D3.3 "First data-driven reconstruction of context-specific network"
This deliverable contains a description of the algorithms implemented for data-driven reconstruction of context–specific networks. The reconstruction of context–specific networks, e.g., prostate cancer–specific, treatment-specific) can help to better understand and describe complex disease progression, and ultimately reveal unknown interactions fundamental to the generation of new treatment hypotheses. In this work, we present a set of algorithms developed by the partners of the PrECISE consortium, and discuss the results of the analysis of various datasets using these devised algorithms.

D3.4 "Identification of systematic alterations of networks for different prognosis and for different clonal composition"
We report on our use of mutations targeting mutated genes to predict prognosis in a larger prostate cancer cohort, namely, the TCGA PRAD dataset. Our results suggest that mutations at the loci of our selected genes are predictive of the overall outcome of prostate cancer patients.

WP4:

D4.1 "Interactome of molecular interactions in prostate cancer"
The goal of this deliverable was to integrate patient data of the ProCOC cohort into a molecular map specific to prostate cancer. The integrated molecular map is also called network of molecular interactions or interactome. The interactome built from patient data is based on protein measurements of tumor samples from patients. By combining multiple inference methods a data-driven consensus interactome was constructed. To assess the performance of the inference methods we applied the methods to simulated data on known biological networks. To enrich the data driven interaction network, separate interactomes were extracted from publicly available interaction data bases and from publications. We compared the interactomes derived from data and publications to interaction networks from public databases. By combining the interaction networks derived from data, public databases and publications a consensus interactome was built.

D4.2 "Catalogue of molecular alterations and dysregulated pathways"
Patient mutations for the ProCOC cohort were projected on a prostate–specific network topology to better explain observed clinical phenotypes and tumor sub-typing

D4.3 "Robust cross-cohort clinical patient classifier"
In this report a method called PIMKL developed by partner IBM is presented. PIMKL is a machine learning approach to analyze different omics data in a disease specific fashion that makes use of an interactome and pathway annotation as prior information. PIMKL was applied on different cohorts made available from partner UZH and ETH.

WP5:

D5.1 "Generic model"
Logical models are simple, require in principle no quantitative information, and can be hence applied to large networks combining multiple pathways. This deliverable presents some analyses made on a model, which is derived describing the network dynamics in specific contexts (dependent on initial conditions or perturbations for instance). Some physiological conditions are first simulated in order to validate the model. The validation concerns both the choices made on the topology of the network (players and the interactions), and on those on the logical rules that are associated to each of the variable of the model. Then, some modifications of the wild type are explored, corresponding to mutants. The model still has to be validated on patient or clone profiles, and on data by performing some computations on the activity of pathways in the PC39 patients.

D5.2 "Proteomic data sets in cancer cell lines"
This report describes two proteomic profiles – full cell proteome and phosphoproteome – in castration sensitive and castration resistant cell lines upon drug perturbations. Full cell proteome is already being used by TUDA and IBM in WP3, while the phospho-proteomic data will be analysed in task 5.4.

D5.3 "Patient-specific models"
This deliverable describes the instantiations of our generic Boolean model of prostate cancer to adapt it for different patients.

WP6:

D6.3 "Generate SWATH proteome profiles from sample punches prepared in D6.2"
This report consisted of acquiring mass spectrometric proteomics data from the generated punches from the three cohorts described in D6.2 “Generate multiple punches from each validation sample in D6.1”:

(1) Fresh frozen (FF) prostate tissue from normal and tumor areas of prostate cancer (PC) patients with radical prostatectomy from the prostate cancer outcomes cohort study (ProCOC), also referred as PPP1 cohort.

(2) A set of retrospective formalin-fixed paraffin-embedded (FFPE) PC cohort of radical prostatectomy specimens (ZTMA76)

(3) FFPE samples from castration resistant prostate cancer (CRPC) patient tissue (not acquired yet)

Preliminary results of analysis of PPP1 data indicated, that findings obtained with PC39 project, are valid in this dataset as well.

D6.4 "Generate amplicon sequencing profiles from sample punches prepared in D6.2"
Here, part of the samples from MetaProc and ZTMA204 have been sequenced in different tumor areas as described in D6.2. The remaining samples were prepared for sequencing at multiple time points to better inform and validate algorithms developed by BCM and IBM in WP1 “Regulatory network and clonality inference in prostate cancer tumors”.

WP7:

D7.1 "Data input and input interface"
Prostate specific gene regulatory networks were inferred by integration of RNASeq data measurements from TCGA PRAD and ProCOC cohorts using HIPSTER framework.

D7.2 "Design and integrate pathway visualization"
The visualization of genomic, transcriptomics and proteomics data onto maps describing molecular processes proves to be informative. At a first glance, by mapping these data onto maps of processes known to be altered in cancer, some signalling pathways or processes show a higher expression in specific patients or groups of patients and suggest which deregulations are associated with which (groups) of patients. In this deliverable, we demonstrate how visualization of expression data or of pathway activity can provide a first understanding of differences between patients with different clinical information.

D7.3 "Re-implement methods"
We report on the re-implementation and integration of our interface to accommodate the variety and changes in the design of clinical and wet-lab data, as well as analysis methods and products developed by PrECISE into a secure system with varied storage, visualization, and integration capabilities. The system provides a single-point access to tools developed by our partners, as well as molecular data and pathways, dedicated storage, and data and analysis visualizations. The re-implemented interface allows researchers and clinicians to compare their PC results with a wide-range of mutation, transcriptomic, proteomics and clinical findings as well for better outcome estimations. The provided system is ready to be used within PrECISE and is projected to become available for other researchers and clinicians following the completion of the project.

WP8:

D8.2 "Data Management Plan (DMP)"
The purpose of the DMP is to provide an analysis of the main elements of the data management policy that will be used by the applications with regard to all the datasets that will be generated by the project. The DMP should ensure that most important aspects regarding data management, like metadata generation, data preservation, and responsibilities, are identified in an early stage of the project. This ensures that data is well-managed during the project and also beyond the end of the project. Data which will be generated in the course of the project include output data of random number generators, PUF output data, measurement data, and source code. As the DMP is an incremental tool, it will be adapted in the course of the project.
