The antibody binding was visualized with 3, 3'-diaminobenzidine tetrahydrochloride (DAB) before brief counterstaining with Mayer's hematoxylin. The degree of immunohistochemical staining was recorded using a semiquantitative and subjective grading system. The mRNA expression of Rot2 was examined by real time reverse transcription polymerase chain reaction, including nineteen of the 85 HCC and three normal liver tissues. The ratios of Ror2 to the housekeeping gene GAPDH represented the normalized relative levels of Ror2 expression. To determine the prognostic factor, the outcome of the 82 patients was determined by reviewing their medical charts. The overall and diseasefree survival rates were estimated using the Kaplan-Meier method and compared with the logrank test. The prognostic analysis was carried out with univariate and multivariate Cox regressions models.RESULTS: Compared to nontumorous (hepatitis or cirrhotic) tissues, Rot2 mRNA expression was clearly decreased in HCC. Rot2 and Wnt5a protein expressions in the majority of HCC patients (63% and 77%, respectively) was significantly less in tumor tissues, as compared to adjacent nontumorous tissues, and this reduction was correlated with increasing serum α-fetoprotein and tumor stage. In 68% (58/85) of the HCC cases, the expression of IB-catenin in tumor tissues was either downregulated in the cellular membrane, upregulated in the cytoplasm, or both. Survival analysis indicated that Wnt5a and Ror2 protein expressions could be regarded as independent prognostic factors for HCC; HCC patients with decreased Wnt5a or Ror2 protein expression had a poorer prognosis than those with elevated Wnt5a and Ror2 expression (P = 0.016, P = 0.007, respectively).CONCLUSION: Wnt5a and Ror2 may serve as tumor suppressor genes in the development of HCC, and may serve as clinicopathologic biomarkers for prognosis in HCC patients.展开更多
