  1. HPN-DREAM Breast Cancer Network Inference Challenge - Participants in this Challenge will be provided with an extensive proteomics time-course dataset on four breast cancer cell lines and tasked with analyzing these data to solve the following 3 sub-challenges: 1) build network models that represent the active cell signaling pathways in breast cancer, 2) predict the dynamic response of various phospho-proteins to drug perturbations, and 3) propose novel strategies to visualize these high dimensional data.
  2. NIEHS-NCATS-UNC DREAM Toxicogenetics Challenge - We will provide genetics and transcriptomics information of the 1000 Genomes Project (www.1000genomes.org), as well as cytotoxicity measures derived from compound exposure to over a hundred toxic agents using the 1000 genomes lymphoblastoid cell lines. Participants are tasked with solving two related subchallenges: (1) develop predictive models of cytotoxicity using genetic and genomic data to predict individual responses to compound exposure and (2) use chemical attributes to predict population-based cytotoxicity characteristics (median, variance) for a set of compounds.
  3. The Whole-Cell Parameter Estimation DREAM Challenge - Participants will be provided with a whole cell model of Mycoplasma genitalium and tasked with estimating the model parameters for specific biological processes from simulated data. The simulated data to be provided represents possible measurements in actual experiments: participants will will have a credit budget and will be able to purchase simulated data on demand with the aim to refine the parameters under estimation.

  1. Network Topology and Parameter Inference Challenge -

    Participants are asked to develop and/or apply optimization methods, including the selection of the most informative experiments, to accurately estimate parameters and predict outcomes of perturbations in Systems Biology models, given the complete and incomplete structure of the model for a gene regulatory network. Results were published in Meyer et al BMC Sys Bio 2014. 

  2. Sage Bionetworks-DREAM Breast Cancer Prognosis Challenge - The goal of the breast cancer prognosis Challenge is to assess the accuracy of computational models designed to predict breast cancer survival, based on clinical information about the patient's tumor as well as genome-wide molecular profiling data including gene expression and copy number profiles.
  3. The DREAM Phil Bowen ALS Prediction Prize4Life - The goal of this challenge is to predict the future progression of disease in ALS patients based on the patient’s current disease status. The data available to make this prediction includes demographics, medical and family history data, functional measures, vital signs, and lab data (blood chemistry/hematology/urinalysis). These data have been obtained from industry, academic, and government-funded clinical trials. The prize award is $50,000.
  4. NCI-DREAM Drug Sensitivity Prediction Challenge -

    The challenge is to use genomic information to build models capable of ranking the sensitivity of cancer cell lines to a set of small molecule compounds or their combinations.
