Evangelia Petsalaki: New Systems Biology Approach Identifies Biomarkers in Thrombotic APS
Evangelia Petsalaki, Director of Oncology Data Science Innovation at GSK and Visiting Group Leader at EMBL-EBI, shared on LinkedIn about a recent article she and her colleagues co-authored, published in medRxiv, adding:
”We’re pleased to share our latest preprint on thrombotic primary antiphospholipid syndrome (APS).
In this study, we integrated plasma proteomics, whole-blood transcriptomics, machine learning and network-based analysis to investigate the molecular programmes associated with high-risk disease.
Across multiple complementary analyses, we found evidence for a complement- and interferon-associated thromboinflammatory programme linked to increasing antiphospholipid antibody burden and recurrent thrombosis. Integrating the data using multi-omics factor analysis and network propagation also connected circulating protein signatures to intracellular signalling pathways, providing a systems-level view of disease biology.
Among the findings, Complement Factor D (CFD) emerged as a candidate biomarker associated with recurrent thrombosis, although this will require validation in independent cohorts.
This work was a fantastic collaboration between colleagues at EMBL-EBI, the National and Kapodistrian University of Athens, and the Biomedical Sciences Research Center ‘Alexander Fleming’.
Many thanks to everyone involved, especially Srijith Sasikumar and Maria Tektonidou as well as our coauthors Michail Baltsiotis, Kleio-Maria Verrou, Georgia Rouni, Martina Samiotaki, Petros Sfikakis and the rest of the team.”
