In this study we investigated the expression profiles of the EMT markers, the relationship between EMT markers and patient/tumor/viral factors, and the interplay between major EMT regulators in human hepatocellular carcinoma (HCC). Reduced E-cadherin and nonmembranous -catenin expression, the hallmarks of EMT, were shown in 60.2% and 51.5% of primary HCC samples, respectively. Overexpression of Snail, Twist, or Slug, the major regulators of EMT, was identified in 56.9%, 43.1%, and 51.4% of primary HCCs, respectively. Statistical analysis determined that Snail and Twist, but not Slug, are major EMT inducers in HCC: overexpression of Snail and/or Twist correlated with down-regulation of E-cadherin, nonmembranous expression of -catenin, and a worse prognosis. In contrast, there were no such significant differences in samples that overexpressed Slug. Coexpression of Snail and Twist correlated with the worst prognosis of HCC. Hepatitis C-associated HCC was significantly correlated with Twist overexpression. HCC cell lines with increased Snail and Twist expression (e.g., Mahlavu) exhibited a greater capacity for invasiveness/metastasis than cells with low endogenous Twist/Snail expression (e.g., Huh-7). Overexpression of Snail or/and Twist in Huh-7 induced EMT and invasiveness/metastasis, whereas knockdown of Twist or Snail in Mahlavu reversed EMT and inhibited invasiveness/metastasis. Twist and Snail were independently regulated, but exerted an additive inhibitory effect to suppress E-cadherin transcription. Conclusion: Our study provides a comprehensive profile of EMT markers in HCC, and the independent and collaborative effects of Snail and Twist on HCC metastasis were confirmed through different assays.

Methods 40 patients with advanced hepatocellular carcinoma were randomly divided into two groups.One group underwent intrahepatic arterial infusion of Endostar combined with TACE and compared with another group who underwent normal TACE.CT or MRI and DSA were reexamined regularly.The tumor relapse,metastasis and new-born vessels were observed.The effects were evalued according to RECIST and AFP.Qulity of life,survival rate and side effects were assessed. Results The survival rate of one-year and the degree of AFP decline were higher in the group treated with Endostar combined with TACE. Conclusion Transcathete arterial infusion of Endostar combined with TACE can significantly increase the survival rate and decrease AFP in patients with adcanced hepatocellular carcinoma.The new-born vessel and metastasis were controlled.This treatment is safe and worthy of clinical generalization and further observation.
