Visualization of eIF2α expression. It used a Zeiss LSM 760 confocal microscope with a C-Apochromat 20x objective lens. The expression level of eIF2α significantly increased in the “A549-OC43” than in the “A549-OC43 + drug” (A549-WT: A549 cells with no treatment; A549-OC43: A549 cells treated with OC43; A549-OC43 + drug: A549 cells treated with OC43 and HGYGT).
