Combination of approaches to characterize vimentin lipoxidation and assessment of consequences of vimentin lipoxidation.

Activity Approach Reference
Identification and Characterization of Vimentin
Identification as putative target for lipoxidation 15d-PGJ2B→Electrophoresis → WB → Detection of biotin → MALDI-TOF-MS Stamatakis et al. [284]
HNE → Electrophoresis → Anti-HNE-WB → Nano-LC-MALDI-MS/MS Chavez et al. [283]
Cell Senescence→Electrophoresis → Anti-HNE-WB → MALDI-TOF-MS Aldini et al. [220]
Confirmation of lipoxidation site in cell cyPG(biotinylated) → Immunoprecipitation → Detection Biotin Aldini et al. [220]
cyPG(biotinylation) → Immunoprecipitation → SDSPAGE → LCMS/MS Gharbi S et al. [282]
Carbonyl derivatization → Avidin enrichment → MS/MS Chavez et al. [283]
Validation of lipoxidation site (Cys328) Transfection → cyPG(biotinylation) → Avidin enrichment → SDSPAGE → WB Gharbi et al. [275]
Carbonyl derivatization → Avidin enrichment → MS/MS Chavez et al. [283]
Analysis of lipoxidation in vitro cyPG(biotinylation) → SDSPAGE → Biotin Detection Gharbi et al. [282]
cyPG(biotinylation)/HNE → SDSPAGE → Biotin Detection/Anti-HNEWB Aldini et al. [220]
Confirmation of lipoxidation site in vitro (Cys328) cyPG(biotinylation) → Digestion and Avidin enrichment → MALDI-TOF-TOF MS/MS Gharbi et al. [282]
In vitro competition assays Aldini et al. [220]
Functional Assessment of Vimentin Lipoxidation
In vitro assessment of lipoxidation: Filaments derangement HNE → Polymerization (NaCl Induced) → Filaments electron microscopy Aldini et al. [220]
In cell assessment of lipoxidation (Condensation of network by HNE treatment) Transfection of cells (expressing vimentin) with GFP → HNE treatment → Confocal microscopy Aldini et al. [220]
Cys328 in function consequences of vimentin lipoxidation: network condensation and filaments preservation in vimentin Cys328ser Transfection of vimentin or Cys328ser in cell (vimentin deficient) → HNE treatment → Immuno-fluorescence → Confocal microscopy Aldini et al. [220]
