ABSTRACT
<p><b>OBJECTIVE</b>To analyze the gene expression level of fibroblast activation protein in HBV related hepatocellular carcinoma patients and discuss its clinical significance.</p><p><b>METHODS</b>FAP gene expression in 33 hepatocellular carcinoma patients cancer tissues, peficancerous tissues, distant relative normal liver tissues and 13 normal liver tissues were examined by reverse transcription PCR; and real-time fluorescent quantitative PCR (qRT-PCR) was used to quantify their expression.</p><p><b>RESULTS</b>FAP were expressed in all the tissues,the relative expression values in cancer tissues, peficancerous tissues and distant relative normal liver tissues were 5.14 +/- 6.69, 1.58 +/- 0.96, 1.63 +/- 0.94, respectively, the differences were statistically significant (F = 4.401, P < 0.05); and in TNM stage I, II, IIII, they were 2.89 +/- 3.35, 4.15 +/- 4.69, 10.09 +/- 9.51 respectively; in well-differentiated, differentiated and poorly differentiated hepatocellular carcinoma were 1.62 +/- 1.74, 3.84 +/- 3.79, 1.26 +/- 13.34 respectively. The differences were all statistically significant (P < 0.05).</p><p><b>CONCLUSION</b>FAP may play an important role in the occurrence and development of HBV related hepatocellular carcinoma.</p>
