A DIAGNOSTIC MARKER FOR HEPATOCELLULAR CARCINOMA COMPRISING ANTI-FASN AUTOANTIBODIES AND A DIAGNOSTIC COMPOSITION FOR HEPATOCELLULAR CARCINOMA COMPRISING ANTIGENS THEREOF

摘要

The present invention relates to an autoantibody specifically recognizing the epitope sequence of FASN (fatty acid synthase), more particularly, to the autoantibody or a fragment comprising an antigen-binding site thereof, a diagnostic composition for hepatocellular carcinoma comprising an agent capable of assessing the expression level of the autoantibody, a hybridoma cell line producing the autoantibody, a diagnostic kit for hepatocellular carcinoma comprising the composition, a method for detecting the autoantibody of hepatocellular carcinoma patient using the composition, and a method for screening a therapeutic agent for hepatocellular carcinoma by administering candidate materials for hepatocellular carcinoma treatment to confirm a reduction in the expression level of autoantibody.
