t-Bid induces EAA-L4CL formation in isolated mitochondria and ApAP dose-dependently inhibits L4CL oxidation and epoxyalcohol-aldehyde-CL formation.(A) Total ion chromatogram (TIC) of m/z 685.5 (doubly charged) in isolated mitochondria when treated with t-Bid. Arrow shows the putative EAA-CL peak. (B) MS spectrum of CID of m/z 685.5 at 6.33 min, EAA-CL. (C) MRM analysis of L4CL oxidation products in isolated mitochondria after t-Bid treatment. SRM transitions are shown in Methods. (D) ApAP inhibits L4CL oxidation and EAA-CL formation. L4CL oxidation products are expressed as % of relative inhibition.
