Cell Envir Cond:37°C in humidified 5% CO2
Cell Harvesting:After 48 h of transfection the cells were washed three times with ice-cold PBS (3x5 mL) and the celles were collected using a cell scraper. Ice-cold water (3 mL,sterile, MilliQ) was added to the samples. The suspension was transferred to a 15 mL polypropylene tube and then snap-frozen in liquid N2 and stored on ice for 5 min. The cells were lysed by two freeze-thaw cycles where the cells were thawed at 37°C in a water bath and frozen using liquid N2. Subsequently, the cells were sonicated in a

Sample Preparation:

Sampleprep ID:SP000942
Sampleprep Summary:The samples were thawed at room temperature and subjected to centrifugation for 17 min at 3000 rpm and 4°C. A quality control (QC) sample was created by pooling an equal volume from all samples. The aqueous supernatants were transferred to clean extraction tubes followed by addition of chloroform and methanol for the final proportion 2.85:4:4 water:methanol:chloroform. The extraction tubes were gently vortexed and then stored at 8°C for 20 min prior to centrifugation for 20 min at 3000 rpm and 4°C. The aqueous phases were recovered and evaporated to dryness at 40°C under N2. All samples were stored at -80°C after evaporation. Prior to analysis the samples were reconstituted in acetonitrile:Milli-Q water 90:10
Processing Method:lysis, freeze thaw cycles and sonication (see cell harvesting)
Processing Storage Conditions:Room temperature and 8°C during extraction, -80°C before and after extraction
Extraction Method:Liquid Liquid Extraction using CHCl3:MeOH:H2O 4:4:2.85
Extract Storage:Extracts were stored in -80°C after evaporation
Sample Resuspension:Acetonitrile:Milli-Q water 90:10

Chromatography:

Chromatography ID:CH001027
Chromatography Summary:The samples were analyzed on a Acquity UPLC I-class system from Waters. A HILIC-Amide column (1.7 μm, i.d. 2.1x50 mm) from Waters was used for sample separation and a non-linear gradient elution profile from 100 % A to 100 % B was used. Mobile phase A consisted of 90:10 acetonitrile/water with 10 mM ammonium formate and 0.1% FA while mobile phase B consisted of 50:50 acetonitrile/ water with 10 mM ammonium formate and 0.1% FA. The flow rate was 0.3 ml/min, the column temperature 40°C and the injection volume 5 µL.
Instrument Name:Waters Acquity I-Class
Column Name:Waters Acquity BEH Amide (50 x 2.1mm,1.7um)
Column Temperature:40°C
Flow Gradient:Non-linear gradient elution profile from 100 % A to 100 % B was used. In detail; 100% A was kept for 0.5 min then decreased non-linearly (slope-factor 8 in MassLynx) over 12.5 min to 100% B, 100% B was held for 3 min followed by 7 min at 100 % A to re-equilibrate the column for a total run-time of 23 min.
Flow Rate:0.3 ml/min
Injection Temperature:4°C
Sample Injection:5 μl
Solvent A:90% acetonitrile/10% water; 0.1% formic acid; 10 mM ammonium formate
Solvent B:50% acetonitrile/50% water; 0.1% formic acid; 10 mM ammonium formate
Analytical Time:23 min total sample run-time
Randomization Order:All samples were analyzed in a randomized order with three QC injections interspaced every eleventh injection
Chromatography Type:HILIC

MS:

MS ID:MS001348
Analysis ID:AN001460
Instrument Name:Waters Synapt G2 QTOF
Instrument Type:QTOF
MS Type:ESI
MS Comments:The raw data was converted to NetCDF files using the software DataBridge (Masslynx version 4.1, Waters). Peak detection and retention time alignment was performed using the R based software XCMS (Smith et al. 2006). The centWave function was used for peak detection and the function parameters were set as follows; the maximal deviation in m/z between scans was set to 8 ppm, the maximal and minimal peakwidth was set to 5 and 25 s respectively and the signal to noise ratio cutoff was set to 10. Retention time correction was performed using the “obiwarp” function.
