Nano-ZnO exposure induced EMT. A. Exposure of Nano-ZnO (30 μg/mL) for 24 and 48 h in HBE cells with or without p53 presence. The cell morphology was took by light microscope. Scar bar: 50 μm. B. Nuclear protein was subjected to Western blot. E-cadherin, N-cadherin, and Vimentin were detected their proteins’ expression
