Schematic representation of the signaling events that might underlie the toxic effects elicited by DON intoxication on energy metabolism and liver steatosis. In an initial phase (3 h), DON induced a hormonal storm (insulin, adrenaline and corticosterone release) associated with a rise in liver lipogenesis and adipose tissue lipolysis. Moreover, inflammation and ER stress were observed within the liver and adipose tissues. A second phase intervened between 6 and 12 h where the increased blood NEFAs and TG resulting from adipose lipolysis and the drop in liver beta oxidation and lipolysis drive liver steatosis.
