Nano-ZnO exposure induced EMT in vivo. A. HE staining of mice lungs’ pathology after 50 mg/kg/day installed per mouse of Nano-ZnO and lungs were collected at day 7 after exposure, Scar bar: 200 μm or 50 μm. B. TEM detection of mice lungs. Red arrows mean the mitochondrions while the yellow mean the nanoparticles. C. Nuclear protein was subjected to Western blot. γ H2AX and Ku70 were detected their proteins’ expression
