Oncogenic pathway identification    

Groundbreaking molecular phenotyping

Revealing tumor-driving mechanisms

OncoSignal assesses the activity of cell signal transduction pathways which drive tumor growth.

mRNA levels regulated by the pathway transcription factor are measured and translated into a quantitative pathway activity score.


OncoSignal pathway analysis can be used to reveal aberrant activity of signaling pathways in tumor cells enabling applications for drug response monitoring*, stratification for clinical trials and for cancer research.

    Functional signaling Pathway ACtivity complementing DNA Mutation ANalysis for precision medicine (PACMAN)

    PACMAN will test how well the OncoSignal solution increases the effectiveness of new, personalised cancer therapy. Significant progress has been made with targeted drugs that block tumour-driving molecular pathways, but it is still difficult to predict how patients will respond. OncoSignal was designed to improve selection of optimal personalised therapy for individual patients.




    OncoSignal will contribute to disruption of cancer care by moving from treatment based on cancer type to tumour biology. Assessment of the functional molecular phenotype will provide improved therapy response prediction compared to DNA genotyping analysis alone. The project promises to:


    • improve clinical outcomes, especially for hard-to-treat cancers;
    • reduce unnecessary side effects from ineffective therapies;
    • save costs due to more effective (personalised) therapies.
