ACTB and viral infectious disease: Figure 11e shows that the LC3-II/β-actin ratio increased significantly in the lungs, spleens, and kidneys of pigs treated with 75 μg/kg OTA and in the BLN of pigs treated with 75 and 150 μg/kg OTA, compared with pigs that received basal diet. The LC3-II/β-actin ratios in the examined tissues were generally consistent with the viral infection levels in those tissues.
