d a significant decrease in cancer-free intervals and overall survival for those patients who had a reduction in E-cadherin function," explained Dr. Wu. A downregulated expression of E-cadherin was also associated with large tumor size and multi-nodular tumors.

Results show that co-expression Snail and Twist (transcription factors or proteins that control when genes are switched on or off) indicates the worst prognosis for HCC patients. "Our research is the first to prove that the two proteins (Snail and Twist) work independently, but together promote EMT," noted Dr. Wu.

According to the study, overexpression of Twist is correlated with HCV-related HCC, partially explaining the highly invasive behavior and poor prognosis for patients with this form of liver cancer. Dr Wu added, "Our results provide essential information for determining HCC prognosis in patients and identifies possible new treatments for future HCC management."
