| 内容記述 | The epithelial-to-mesenchymal transition (EMT) is an initial, critical step in hepatocellular carcinoma (HCC) tumor invasion and metastasis. Frizzled 2 (Fzd2) expression might drive EMT through the non-canonical Wnt pathway, one of the various EMT signaling pathways. The expression of epithelial (E-cadherin) and mesenchymal (vimentin) markers, as well as that of Wnt5b, Stat3, IL-6, Jak2 and Fzd2, were measured in 15 HCC cell lines. The EMT status (vimentin to E-cadherin mRNA expression ratio), Fzd2 mRNA expression, and pSTAT3 protein expression were assessed by immunostaining in 100 HCC patients, and correlations of their expression with clinicopathological factors and prognosis were analyzed. Cell proliferation, migration, and invasiveness were assessed after Fzd2 knockdown. Fzd2 expression was significantly correlated with a mesenchymal phenotype in the HCC cell lines. Treatment of the cell lines with Fzd2 siRNA resulted in significantly reduced migration and invasiveness but did not affect proliferation. A significant correlation was detected between the EMT status and Fzd2 expression in the HCC patients. Multivariate analysis revealed that Fzd2 expression was an independent predictor of recurrence (P=0.034). Patients with high Fzd2 expression had significantly poorer recurrence‑free survival than those with low expression (P=0.03). Finally, pSTAT3 expression was significantly correlated with the EMT and Fzd2 status (P=0.0028, and P=0.0066, respectively). Fzd2 expression induced EMT and enhanced cell migration and invasiveness, and it might be a novel predictor of HCC recurrence. Furthermore, Stat3 might be controlled by both the Wnt5/Fzd2 and IL-6/Jak2 signaling pathways and play an important role in EMT. | |||||
