Task: Answer Verification
Input (English): Question: Does microRNA-181a promote tumor growth and liver metastasis in colorectal cancer by targeting the tumor suppressor WIF-1?
Answer: Our data demonstrate that miR-181a expression is associated with CRC liver metastasis and survival. miR-181a has strong tumor-promoting effects through inhibiting the expression of WIF-1, and its potential role in promoting epithelial-mesenchymal transition.
Output (English): yes
