Study TitleEffect of external high-dose rate radiation on mouse biofluid metabolomic signatures (neg)
Study SummaryIn the event of an improvised nuclear device (IND), a complex IR exposure will occur consisting of both low (LDR) and high-dose rates (HDR). We have previously addressed LDR exposures from internal emitters or externally deposited radionuclides on biofluid small molecule signatures, but further research on the HDR component is required. Here, we exposed 8 − 10 week old male C57BL/6 mice to a cumulative dose of 3 Gy using a reference dose rate of 0.7 Gy/min or a HDR of 7 Gy/sec, collected urine and serum at 1 and 7 d, then compared the metabolite signatures using an untargeted (urine) approach with liquid chromatography mass spectrometry platforms.

Collection:

Collection ID:CO002255
Collection Summary:Spot urine collected before and after irradiation
Sample Type:Urine
Storage Conditions:-80℃

Treatment:

Treatment ID:TR002274
Treatment Summary:This novel irradiator is based on a Clinac 2100C (Varian Medical Systems, Corona, CA, USA) where the pulse delivery is controlled using in house software. All irradiations were performed using 9 MeV electrons with no scatterer or flattening filter. For these experiments, mice were placed in a 72 mm x 41mm x41mm acrylic box in which air holes had been drilled (The Container Store, Coppell, TX, USA). For 0.7 Gy/min irradiations, mice (n=6) were individually placed at 120 cm above the clinac head and irradiation delivered at 3.25 pulses per second. In this configuration, 3 Gy was delivered in 580 pulses. For 7 Gy/sec mice (n=6) were individually placed 20cm above the clinac head (Figure S1) and dose delivered at 180 pulses/sec after allowing 20 sec where the acceleration and electron source were both on but operated asynchronously so that no beam is delivered. In this configuration, 3 Gy was delivered in 78 pulses.

Sample Preparation:

Sampleprep ID:SP002268
Sampleprep Summary:[17,18]. Briefly, urine (20 μl) was deproteinized (80 μl 50% cold acetonitrile) with internal standards (2 μM debrisoquine [M+H]+ = 176.1188; 30 μM 4-nitrobenzoic acid [M-H]- = 166.0141), vortexed, incubated on ice (10 min), and centrifuged for 10 min (max speed, 4 °C). A 1 μl aliquot of each sample was combined for a quality control (QC) sample.
