Mitochondria were isolated from MEC treated with TPP-C18:1 (50?��M, for 2?h at 37?��C) as described [27]. TPP-C18:1 was Tubulin extracted from mitochondria by Folch procedure [24] and LC/MS in positive mode was performed using a Dionex Ultimate? 3000 HPLC coupled on-line to a linear ion trap mass spectrometer (LXQ Thermo-Fisher). TPP-C18:1 and TPP were separated on a normal phase column (Luna 3?��m Silica 100A, 150?��?2?mm, (Phenomenex, Torrance CA)) with flow rate 0.2?mL/min using gradient solvents containing 5?mM CH3COONH4 (A �C n-hexane:2-propanol:water, 43:57:1 (v/v/v) and B �C n-hexane:2-propanol:water, 43:57:10 (v/v/v). At these conditions the retention times for TPP-C18:1 and TPP were 27.9 and 50.6?min, respectively. The results are presented as mean?��?S.E.M. values from at least three experiments, and statistical analyses were performed by either paired/unpaired Student��s t-test or one-way ANOVA. The statistical significance of differences was Selleck NLG919 set at P?Verteporfin [19]. We found a significant decrease in the amount of polyunsaturated CLs in cells challenged with AcD (vs control cells) �C in line with likely peroxidative ��consumption�� of polyunsaturated molecular species of CL. The oxidation was selective: significant decreases of the contents occurred only in four molecular species of CL �C with m/z 1448, m/z 1472, m/z 1494 and m/z 1496 �C containing C18:2, C20:4, and C22:6 fatty acid residues and corresponding to (C18:2)4, (C18:2)3(C20:4), (C18:2)2(C20:4)2 and (C18:2)3(C22:6), respectively ( Fig. 1Bb). Quantitative assessment of oxidized CL revealed accumulation of oxidation products formed from these CL molecular species ( Fig. 1Bc,d) that were represented by species containing 1�C4 oxygens in their fatty acid residues ( Fig. 1Bc, inserts). We reasoned that delivery of TPP-conjugated monounsaturated C18:1 into mitochondria would favor its integration into CL through acyl-CoA-dependent remodeling pathways by MLCL AT or ALCAT 1 [6], [12]?and?[13]. Using an uncoupler might be diagnostic of potential-driven accumulation of TPP-C18:1 in mitochondria.
