MAOA and non-small cell lung carcinoma: In this study, we demonstrated that HPV-16 E7 oncoprotein enhanced MAOA expression at both protein and mRNA levels (Figure 1C,D), and MAOA knockout inhibited the migration, invasion, and EMT induced by HPV-16 E7 oncoprotein in A549 and NCI-H460 NSCLC cells (Figure 2,3).
