Non-small cell lung cancer is the most common type of lung cancer and is a frequent cause of death. In our research, A549 and SK-MES-1 were used to assess the effect of three-dimensional (3D) culture compared to that of two-dimensional (2D) monolayers in cell proliferation, migration, and invasion, response to chemotherapy, as well as the expression of epithelial to mesenchymal transition (EMT) and cancer stem cell (CSC)-related markers. As tadalafil is a phosphodiesterase type 5 (PDE5) inhibitor with the potential to target CSC maintenance in multiple cancer cell lines, we assessed its function in 3D culture and detected the downstream pathway genes.
