[Significance of glypican-3 mRNA expression in hepatocellular carcinoma tissues and peripheral blood cells].

Objective: To investigate the expressions of glypican-3 (GPC3) mRNA in hepatocellular carcinoma (HCC) tissues and peripheral blood cells (PBCs), and to determine the values of GPC3 mRNA in the diagnosis of HCC and HCC micrometastasis.

Methods: Using semi-quantitative and nested reverse transcription polymerase chain reactions (RT-PCR), we detected the expressions of AFP and GPC3 genes in the tissues of 41 HCC, 41 paracancer and 52 non-HCC liver samples (41 far from HCC tissues and 11 normal liver tissues), and in the PBCs of 67 specimens from subjects.

Results: The semi-quantitative RT-PCR displayed GPC3 mRNA was expressed in all samples of tissues and PBCs, and the relative intensities of its expressions in HCC, paracancer, non-HCC liver tissues were 78.
