However, some studies recently suggested that the role and expression of E-cadherin might be more complex and diverse. In the present study, we evaluated the prognostic value of E-cadherin expression on membrane, cytoplasm, and membrane/cytoplasm ratio in hepatocellular carcinoma (HCC) patients after curative hepatectomy. Methods: The expression of E-cadherin was assessed by immunohistochemistry in HCC tissue microarrays from 125
patients, and its prognostic values and other clinicopathlogical data of HCC patients were retrospectively analyzed. Patients were followed for a median period of 43.7 months (range 1 to ABC294640 mouse 126 months). Results: Univariate analysis demonstrated that high membrane/cytoplasm (M/C) ratio of E-cadherin expression was associated with poor overall survival (OS) (P = 0.001) and time to recurrence (TTR) (P = 0.038). Others included tumor size, intrahepatic metastasis, and TNM stage. Whereas neither membrane nor cytoplasm expression of E-cadherin was related with OS and TTR. Furthermore, multivariate analysis confirmed that M/C ratio of E-cadherin expression was an independent predictor of OS (P = 0.031). And χ2 tests showed that M/C ratio of E-cadherin expression were related with early stage recurrence (P = 0.012), rather than later stage recurrence. Conclusion: The M/C ratio of E-cadherin expression is a strong predictor of postoperative survival, recurrence, and associated with early stage recurrence in patients with HCC. Key Word(s): 1.

Traditional chemotherapies targeting most of tumor cells but fails to eradicate CSCs, which might be an important reason of chemoresistance, but the molecular mechanism of chemoresistence in CSCs remains to be studied. Methods: The approach of tumorsphere formation highly enriched CSCs is used to isolate and characterize liver CSCs from HepG2, Hep3B, PLC cell lines.
