Signalling networks


The Network Biology (NetBiol) Group is at the Department of Genetics of the Eötvös Loránd University. The NetBiol Group works in close cooperation with the LINK-Group led by Prof. Peter Csermely and with the experimental C. elegans lab led by Tibor Vellai. Our completed research projects include

  1. the development of a signaling pathway database, SignaLink, which focuses especially on signaling cross-talk,
  2. the identification of novel signaling proteins (signalogs),
  3. the development of the PathwayLinker webservice that analyzes the signaling pathway memberships of proteins as well as their interactors for experiment design and evaluation,
  4. a systems-level examination of the interaction and regulatory network of NRF2, a major transcription factor important in antioxidant response and cancer therapy.

Current research interest

Autophagy, the major catabolic process of eukaryotic cells degrading and recycling damaged macromolecules and organelles, is implicated in several diseases, e.g., cancer and neurodegenerative disorders. In anticancer therapy, medical downregulation of autophagy would be important as radiotherapy and certain cytotoxic drugs were found to induce autophagy and protect the cancer cells. Autophagy is regulated by a complex signaling network, including several pathways and cross-talks between them. Currently, we are using network based approaches and dynamical modeling to uncover key signaling components important in the robustness of the autophagy-regulating signaling network. These key proteins would be unexpected autophagy regulators and possible novel chemotherapic drug targets for intervening autophagy.
