BCL9 and hepatocellular carcinoma: For example, miR-3194-3p is significantly downregulated in hepatocellular carcinoma (HCC) tissues and cells, and miR-3194-3p inhibits the migration, invasion and epithelial-mesenchymal transition (EMT) of HCC cells via suppressing Wnt/β-catenin signaling through targeting BCL9 transcription coactivator (BCL9) [25].
