Guan et al. found that Linc00673-v4-the most abundant transcription of Linc00673 in lung adenocarcinoma cells and a molecular scaffold-enhanced the interaction between DDX3 and CK1e proteins, activated the WNT/β-catenin signaling pathway, and increased the expressions of nuclear β-catenin, VEGF, Twist, HOXB9, and MMP9, which together increased the aggression of lung adenocarcinoma 64. This evidence concerns the gene MMP9 and lung adenocarcinoma.
