Abstract:
Objective To explore the role of the SerpinB5 and β-catenin in occurrence and development of the primary hepatocellular carcinoma (HCC). Methods The expressions of SerpinB5 and β-catenin protein and mRNA in carcinoma tissues and paracancerous tissues of 60 patients with primary HCC were detected by immumohistochemistry and real-time quantitative reverse transcriptional polymerase chain reaction (RT-PCR) methods. Results The positive expression rate of SerpinB5 protein and SerpinB5 mRNA in carcinoma tissues were significantly lower than those in paracancerous tissues:25.0%(15/60) vs. 63.3%(38/60) and 1.12 ± 0.43 vs. 5.19 ± 0.39, and there were statistical differences (P<0.01). The positive expression rate of β-catenin protein and β-catenin mRNA in carcinoma tissues were significantly higher than those that in paracancerous tissues: 65.0%(39/60) vs. 31.7%(19/60) and 4.23 ± 0.25 vs. 1.19 ± 0.17, and there was statistical difference (P<0.01). Decreased SerpinB5 expression was associated with higher serumα-fetoprotein level, larger tumor size, poor differentiation, advanced TNM stage, capsule invasion and tumor thrombosis (P < 0.01 or 0.05). Increased β-catenin expression was associated with poor differentiation, advanced TNM stage, capsule invasion and tumor thrombosis (P < 0.01 or < 0.05). The correlation analysis result showed that SerpinB5 had negative correlation withβ-catenin (carcinoma issues:r=-0.346, P=0.001;paracancerous tissues:r=-0.258, P = 0.024). Conclusions The abnormal expression of SerpinB5 and β-catenin may contribute to the progression and biologically malignant behavior of primary HCC, and SerpinB5 and β-catenin exists synergistic effect in the occurrence and development of primary HCC.
