1 To this aim, we have monitored the effects of DON on (i) cellular morphological changes via optical and transmission electron microscopy, especially in regards to cell viability and mitochondria changes, and (ii) its effects on key regulators of cell apoptosis, including cytochrome c, caspase-9, caspase-3, Bcl-2, Bax, and Bid. deoxynivalenol BCL2 apoptosis regulator Homo sapiens
2 The relative expression profile of Bcl-2 was contrary to that of Bax and Bid, as Bcl-2 expression decreased as the concentrations DON increased, reaching a minimum at the highest concentration of DON. deoxynivalenol BCL2 apoptosis regulator Homo sapiens
3 We concluded that DON-induced apoptosis was caused by mitochondrial dysfunction and subsequent release of cytochrome c into the cytoplasm and successive activation of caspases, and this was likely regulated by Bcl-2 family proteins. deoxynivalenol BCL2 apoptosis regulator Homo sapiens
