Abstract
The expression of CD81, a cell receptor for hepatitis C virus, was examined on cancer cells in hepatocellular carcinoma (HCC) C (n=29) to clarify its clinical role. CD81 was expressed on hepatocyte membrane in non-tumor portions in all patients, however, this was not stained on the cancer cell membranes in 6 of 29. Reverse transcriptase-PCR revealed that CD81 gene expression was not detected in the tumorous portions in 3 of 7 samples. The loss of CD81 was prominent in poorly differentiated HCC (5 of 8) and extrahepatic metastasis patients (6 of 8). The loss of CD81 is associated with differentiation and metastasis of HCC.
