| Study Title | Exploration of Zeb1-dependent changes in the redox-lipidome of MDA-MB-231 cells |
| Study Summary | Human breast cancer MDA-MB-231 wildtype (WT) cells and the stably transduced MDA-MB-231 shZeb1 (stable Zeb1 knockdown) and shCtrl cell lines (control cell line for the stable Zeb1 knockdown) (Spaderna et al. 2008, DOI: 10.1158/0008-5472.CAN-07-5682) were treated with DMSO or RSL3 (1 or 10 µM) for 2 h, 4 h, 6 h or 24 h. The cell pellets were collected and analyzed for their oxidized phospholipid profile by UPLC-MS/MS. Please note that one sample set was measured three times with the same sample-ID, but with different methods (Ox-PE, Ox-PC, Ox-PI), therefore each sub-class has their own raw-data file marked by their corresponding abbreviation (Ox-PE, Ox-PC, Ox-PI; e.g. "210514_MDA_ZEB1_oxPE_dil_UD_std_1ul_JZ_oxPE_MRM_003.wiff", "210514_MDA_ZEB1_oxPC_dil_UD_std_1ul_JZ_oxPC_MRM_002.wiff" or "210514_MDA_ZEB1_oxPI_dil_UD_std_1ul_JZ_oxPI_MRM_001.wiff"). |

| MS Comments: | Targeted MRM with pre-optimized settings and subsequent automated integration of selected signals using Analyst 1.6.3 or Analyst 1.7.1 (Sciex). Oxidized phospholipid species were identified by the fragmentation of [M-H]- (Ox-PE, Ox-PI) or [M+OAc]- (Ox-PC) to the saturated fatty acid anion (16:0 and 18:0) and either the PUFA anion (20:4 and 22:4) with one to three oxygen incorporated or a secondary fragment. Oxidized phospholipids were quantified based on the most intensive, specific transition to the oxidized fatty acid anions. |
| Ion Mode: | NEGATIVE |
