Expression of survivin, p27 and PTEN in hepatocellular carcinoma and their clinical significances / 中华肝脏病杂志

ABSTRACT

<p><b>OBJECTIVE</b>To detect the expression of survivin protein, survivin mRNA, p27 protein, p27 mRNA and PTEN protein in hepatocellular carcinomas (HCC) and their clinical significances.</p><p><b>METHODS</b>Tissue microarrays were constructed. The expression of survivin protein, p27 protein and PTEN protein were evaluated by immunohistochemical methods and in expression of survivin mRNA and p27 mRNA were evaluated by in stiu hybridization respectively in tumor tissues from 141 HCC patients, 128 samples of para-carcinoma liver tissues, 97 liver tissues far from the carcinomas and normal liver tissues from non HCC patients. The relationship of survivin, p27 and PTEN were investigated and a prediction model of HCC was constructed.</p><p><b>RESULTS</b>The expressions of survivin protein (Ridit 95% CI = 0.689+/-0.048, P < 0.01), survivin mRNA (Ridit 95% CI = 0.690+/-0.049, P < 0.01) and p27 protein (Ridit 95% CI = 0.556+/-0.053, P < 0.05) in HCC tissues were significantly increased, while the expression of PTEN protein (Ridit 95% CI = 0.282+/-0.048) in HCC tissues was significantly reduced (P < 0.01).</p><p><b>CONCLUSION</b>Overexpressions of survivin mRNA and p27 protein and reduced expression of PTEN protein might be a valuable marker to predict the presence of HCC.</p>
