Volcano plot analysis of TBHP-induced, iPLA2γ-dependent cleavage of phospholipids. Brain mitochondria isolated from WT mice and respiring in the presence of TBHP are related to mitochondria with no treatment frozen immediately after isolation (A) and to mitochondria treated with TBHP + r-BEL (C). Analogously, brain mitochondria isolated from iPLA2γ-KO mice and respiring in the presence of TBHP are related to mitochondria with no treatment frozen immediately after isolation (B) and to mitochondria treated with TBHP + r-BEL (D). TBHP + CATR treatment is related to mitochondria with no treatment frozen immediately after isolation in WT (E) and iPLA2γ-KO (F) mice. Abbreviations: SFAs, saturated FAs; MFAs, monoenoic FAs; PUFA, polyunsaturated FAs; MLCL, monolysocardiolipin; DLCL, dilysocardiolipin; CL, cardiolipin; LPC, lysophosphatidylcholine; LPE, lysophosphatidylethanolamine; LPG, lysophosphatidylglycerol; LPI, lysophosphatidylinositol; LPS, lysophosphatidylserine. Lipidomics data were collected from n = 6 replicates.
