Several identified proteins may be potential tumor markers or promising new candidate actors for liver carcinogenesis. Functional studies on selected targets are underway to confirm this hypothesis. Conflict of interest statement The authors declare that they have no competing interests. Acknowledgements This work was supported by the Key Science Research Fund
