Expression of Beclin1 in primary hepatocellular carcinoma / 南方医科大学学报

<p><b>OBJECTIVE</b>To detect Beclin1 expression and explore its clinical significance in primary hepatocellular carcinoma (HCC).</p><p><b>METHODS</b>Beclin1 expressions in 10 normal hepatic tissues, 30 hepatitis liver, 30 cirrhotic liver and 50 HCC tissues were detected by immunohistochemical staining.</p><p><b>RESULTS</b>The positivity rates of Beclin1 expression in the HCC, cirrhotic liver, hepatitis liver and normal liver tissues were 78.00% (39/50), 26.67% (8/30), 53.33% (16/30), and 10.00% (1/10), respectively, showing significant differences between them (chi(2)=28.31, P<0.05). Beclin1 expression was significantly higher in HCC tissues than in the cirrhotic, hepatitis and normal liver tissues (chi(2)=20.39, 5.31, and 14.41, respectively, P<0.05), and hepatitis tissues showed significantly higher Beclin1 expression than hepatic cirrhosis tissues and normal hepatic tissues (chi(2)=4.44 and 4.12, respectively, P<0.05).</p><p><b>CONCLUSION</b>The abnormal expression of Beclin1 is closely associated with the pathogenesis and development of primary hepatocellular carcinoma, and may play an important role in this process.</p>

Expressions and significance of Survivin and VEGF in hepatocellular carcinoma / 中国基层医药

Objective To explore the expressions of Survivin and VEGF and relationship between them in hepatocellular carcinoma(HCC).Methods The expressions of Survivin protein and VEGF protein in 50 HCC.30 cirrhosis and 10 normal tissues were assessed by immunohistochemical method.The expressions of Survivin mRNA and VEGF mRNA in 50 HCC,30 cirrhosis and 10 normal tissues were assessed by in situ hybridization.Results The expressions of Survivin and VEGF in cancer tissues,cirrhosis tissues,normal tissues weresignificantly different. The expression of Survivin in HCC tissues was stronger than that in cirrhosis,but the expreesion of VEGF in cirrho- sis was stronger than that in HCC tissues.Conclusion The expression of survivin.is closely associated with the ex- pression of VEGF in HCC and they take positive correlation.The abnormal expressions of Survivin and VEGF are closely associated with the development of HCC.They may play important roles in the development of HCC.
