SIRT3 Acetylation Regulates Mitophagy to Alleviate Deoxynivalenol-Induced Apoptosis in Porcine Alveolar Macrophages Cells.

ABSTRACT: Deoxynivalenol (DON), a global mycotoxin contaminant, induces immunotoxicity in swine and humans by disrupting mitochondrial membrane integrity and activating mitophagy. SIRT3 plays an important role in regulating cell metabolism and various diseases. It also regulates apoptosis (caused by DON) by regulating the mitophagy pathway, but this pathway has not been studied yet. Gene knockout and overexpression of SIRT3 were performed for proteomics and acetylation modification. Therefore, in this study, PAM cells were selected as an in vitro model of DON (1.1 μg/mL) exposure for 24 h. The results showed that the knockout impaired mitochondrial antioxidant function, whereas overexpression improves damage stimulation. DON can also affect the metabolism of immune pathways, but SIRT3 can enrich the
