| Study Title | TAp73 is a marker of glutamine addiction in medulloblastoma |
| Study Type | siRNA constructs targeting p73 (ID: 2671-AMBION) and a non-targeting control siRNA (scramble) were transfected with 10 pM siRNA with lipofectamine 3000 according to the supplier’s protocol for 48 hours |
| Study Summary | Metabolically-targeted therapies hold the promise of offering an effective and less toxic treatment for tumours including medulloblastoma, the most common malignant brain tumour of childhood. Current treatment relies on the sensitivity of these tumours to DNA damage that was discovered more than 50 years ago. Finding new tumour-specific susceptibilities to complement sensitivity to DNA damage is key to developing new more effective adjuvant therapies. The specific metabolic program of tumours is an attractive vulnerability, as restriction diet are low cost and easy to implement. Here, we present compelling pre-clinical evidence that glutamine restriction diet can be used as an adjuvant treatment for p73-expressing medulloblastoma. |

| 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.

| 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. |

| 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. |
