Study IDST000898
Study TitleTAp73 is a marker of glutamine addiction in medulloblastoma
Study TypesiRNA 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 SummaryMetabolically-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.

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.
Ion Mode:POSITIVE
Capillary Temperature:500°C
Capillary Voltage:1 kV
Collision Energy:20- 45 eV collision ramp, MSE acquistion
Source Temperature:120°C
Dataformat:NetCDF
