| Study Title | Lipidomics analysis of maternal obesity model - knock out |
| Study Summary | 10μl liver tissue of 11-12 weeks old male mice from various diet groups with various genetic background were homogenized and lipids were extracted for shotgun lipidomics experiments. Raw files were converted to .mzml files and imported into and analyzed by LipidXplorer software using custom mfql files to identify sample lipids and internal standards. For further data processing, absolute amounts were calculated using the internal standard intensities followed by the calculated mol% of the identified lipids. For Hif1a flox/flox or Hif1a flox/flox;LysMCre/+ mice with a C57BL/6JRcc background, diet groups contain CDm CD, CDm HFD, HFDm CD and HFDm HFD. m: maternal diet |

| MS Comments: | MS1 spectra (resolution 280 000) were recorded in 100 m/z windows from 250 to 1200 m/z (pos.) and 200 - 1700 m/z (neg.) followed by recording MS/MS spectra (res. 70 000) by data-independent acquisition in 1 m/z windows from 200 to 1200 (pos.) and 200 to 1700 (neg.) m/z. Raw files were converted to .mzml files and imported into and analyzed by LipidXplorer software using custom mfql files to identify sample lipids and internal standards. For further data processing, absolute amounts were calculated using the internal standard intensities followed by the calculated mol% of the identified lipids. |
