چکیده

There is increasing evidence for an immune response to cancer in humans, demonstrated in part by the identification of autoantibodies to tumor antigens. The identification of panels of tumor antigens that elicit a humoral response may have utility in cancer screening, diagnosis or in establishing prognosis. Several approaches are currently available for the identification of tumor antigens. We have used a proteomic-based approach for the identification of tumor antigens that induce an antibody response which we have applied to hepatocellular carcinoma, a major type of cancer worldwide. Two-dimensional gel electrophoresis allows simultaneous separation of several thousand individual proteins from tumor tissue or tumor cell lines. Proteins eliciting a humoral response in HCC were identified by 2-D Western blotting using sera from patients with hepatocellular carcinoma, followed by mass spectrometry analysis and database search. The common occurrence of autoantibodies to specific proteins may have utility for HCC screening and diagnosis.

Prognostic molecular markers in hepatocellular carcinoma (Review article

Hepatocellular carcinoma (HCC) is the 5th commonest malignancy worldwide and is the third most common cause of cancer-related death. The prevalence is different in the world. The ability to predict patients at higher risk of recurrence and with a poor prognosis would help to guide surgical and chemotherapeutic treatment according to individual risk. As understanding of hepatocarcinogenesi...
