Other than LSD1, LINC00673 facilitated the interaction between DDX3 (DEAD box RNA helicase) and CK1ε (casein kinase 1ε) and thus the phosphorylation of dishevelled, leading to activation of WNT/β-catenin signaling and aggressiveness of lung adenocarcinoma [15]. The gene discussed is DDX3X; the disease is lung adenocarcinoma.
