The study of regulatory networks (signaling pathways, transcriptional and metabolic networks) is emerging as a major approach in understanding and managing cancers. This systemic perspective allows for a better understanding of the role of genetic and epigenetic modifications, as well as the stability and plasticity of the regulatory network in the tumor phenotype, and the sensitivity or resistance to treatments.
Leveraging principles of systems biology and Artificial Intelligence techniques, our computational DISCO team contribute to:
• Bridge the gap between high-throughput biological data production and analytical tools to enhance our understanding of the systemic principles of tumor biology.
• Investigate cell regulatory networks to unravel cancer tumorigenesis, cellular heterogeneity, and therapy resistance.
• Develop and disseminate AI-powered Bio-IT tools that scientists can readily understand, trust, and effectively utilize for biological investigations.
Towards these goals, we design and develop new algorithms and software for building and analyzing regulatory networks from ‘omics’ data, network-based interpretation and integration of biological systems, network causality, and network-based hypothesis generation. Our approaches range from machine learning, evolutionary computation, and knowledge representation to closed-loop bioscience automation.
We collaborate closely with experimental groups and share our tools as free, open-source packages and web applications. e.g., network inference/reconstruction: LICORN/CoRegNet, PreCisIon; network analysis/interrogation: PEPPER, skyclust, LatNET, cRegMap; network intervention/revision: Adalab, CoRegFlux, GREAT.
Our team receives significant external funding from the European Union and the French National Science Foundation (EC Horizon2020, EC FP7 Chist-Era, INERM-ITMO Cancer, INCa-PLBIO, ANR…).
We regularly welcome master’s and doctoral students, postdoctoral researchers, and engineers. If you would like to join us, please send us your application.

CANTHER.XAI – eXplainable AI engine to accelerate CANcer systems THERapeutics
We propose to develop CANTHER.XAI (eXplainable AI engine to accelerate CANcer systems THERapeutics) to rationalize cancer systems therapeutics research through an AI closed-loop system (Fig.1). This loop comprises three fundamental components:
- Inference (from experimental cellular models)
- Interrogation (to patients)
- Intervention (feedback to cellular models) with regulatory networks.
By utilizing this loop alongside regulatory networks, we bridge the gap between cellular models and human levels to construct a large-scale manifold of disease states using machine learning embedding techniques. As of today, while large molecular datasets are technically available publicly, this data is not accessible to all and not interoperable. CANTHER-XAI aims to aggregate and help the scientific community exploit all available datasets. This large-scale manifold will provide us with crucial insights into master regulators, matched cellular models, actionable interventions, and patient populations likely to respond positively to treatments.
Our vision is for CANTHER.XAI to synergize with scientists and clinicians (see Fig.2), enabling:
- Conducting system-level research with shared models on comparable data from meta-cohorts at least 10 times larger than current possibilities,
- Maximizing the number of discovered and experimentally verified hypotheses, and
- Acting as a collaborator.
Although primarily designed for fundamental cancer systems biology research, discoveries made with CANTHER.XAI can have significant clinical impacts, such as identifying therapeutic targets, molecular classifications, and facilitating drug repurposing efforts.Specifically, our key objectives include:
- Obj1. Developing a knowledge base, CANTHER.KB, and machine learning/network tools, CANTHER.AI, for applying CANTHER.XAI closed-loop concept in cancer systems biology.
- Obj2. Incorporating explainability into CANTHER.XAI, facilitating seamless interaction between scientists and the AI engine.
- Obj3. Evaluating CANTHER.SaaS (Software as a Service) within collaborative organizations of biologists and clinicians to advance systems and precision oncology
The access to CANTHER-XAI through a web browser (i.e. as SaaS) has been confirmed as an excellent solution both for the users and for developers. We anticipate CANTHER.XAI to feature five main outputs (Fig.2):
- CoRegNet: We will use and extend a conceptual tumor regulatory architecture in which the aberrant activity of master regulators is both necessary and sufficient to maintain tumor cell state. Within a tumor, the nature of the network and its activity vary from cancer cells due to genetic and epigenetic heterogeneity, cell location within a tumor, and the presence of stromal cells. The network approach proposed in this project is original mainly in terms of the incorporation into the model of the factor of cooperativity between co-regulators (Elati et al., Bioinformatics 2007, Nicolle et al., Bioinformatics 2015), rendering it closer to the biological reality than most other approaches.
- CoReglink: The translation of TF co-regulatory networks into graphical models and mapping with signaling (Zerrouk et al., Scientific Reports 2020, Miagoux et al., Journal of Personalized Medicine 2021) and/or metabolic (Trejo et al., BMC Systems Biology 2017, Coutant et al., PNAS 2019) networks should also make the joint simulation of regulatory network models possible.
- CoRegMap: Each cancer type is a heterogeneous disease. Several types of heterogeneity have been described: intertumor heterogeneity revealed by the identification of molecularly diverse subgroups of tumors, and intratumor heterogeneity. We will pursue our work on constructing a large-scale manifold of disease states from latent network-based representations (Picchetti et al., BMC Bioinformatics 2015, Dhifli et al., BMC Bioinformatics 2019), the identification and the characterization of molecular subgroups and their matched cellular models.
- CoRegTreat: We will focus on the identification of therapeutic targets and guide the repositioning of drugs based on the paradigm of reversing transcriptional regulatory networks. Therapeutic compounds will not be assessed by their binding affinity to a particular protein, but by predicting their ability to induce a transcriptional response that is anti-correlated with the regulatory program underlying the pathological state.
- CoRegPan: Comparing regulatory networks of different tissues should help in understanding the specificity that may exist in these tissues. Comparing primary vs metastatic provides insight into how cancer tumors adapt to their metastatic environments. Tumor cells use and modify the networks already present in the normal cells of origin. It is therefore of interest to compare networks in tumors and those in the matched normal cells (Champion et al., Bioinformatics and Comp. Biology, 2021).
