To investigate the effects of T-2 toxin on mitochondrial function in TM3 cell.Different concentrations of T-2 toxin(0 nM,1 nM,10 nM,100 nM)were applied to TM3 cells for 24 h,and the effect of T-2 toxin on the proliferation of TM3 cells was detected by MTT assay.The contents of intracellular Ca^2+,reactive oxygen species.mitochondrial superoxide and ATP,the activities of Ca^2+-Mg^2+-ATPase and Na^+-K^+-ATPase and the changes of mitochondrial membrane potential were determined by biochemical methods.Results:T-2 toxin had toxic effects on TM3 cells,which could increase intracellular Ca^2+content,...
