Biochem Physiol Actions: Deoxynivalenol (DON) is a trichothecene mycotoxin that inhibits the synthesis of DNA and RNA as well as protein synthesis at the ribosomal level. DON induces IL-6 mediated serum hyperelevation of IgA, as well as phosphorylation of extracellular signal regulated protein kinases 1 and 2 (ERK 1,2) and c-Jun N-terminal kinases 1 and 2 (JNK 1,2) in mice. An in vitro study with porcine ovarian granulosa cells suggests a dose dependent association of DON on porcine ovarian functions. It was also shown that LPS and its downstream mediators can interact with DON to modulate proliferative, cytotoxic and apoptotic outcomes in leukocytes in a tissue specific manner.
