Study Title | Effects of Microbiome Depletion on Radiation Biodosimetry Metabolomics |
Study Summary | Development of novel biodosimetry assays and medical countermeasures is needed to obtain a level of radiation preparedness in the event of malicious or accidental mass exposures to ionizing radiation (IR). For biodosimetry, metabolic profiling with mass spectrometry (MS) platforms has identified several small molecules in easily accessible biofluids that are promising for dose reconstruction. As our microbiome has profound effects on biofluid metabolite composition, it is of interest how variation in the host microbiome may affect metabolomics based biodosimetry. Here, we chemically ‘knocked out’ the microbiome of male and female C57BL/6 mice (Abx mice) and then irradiated (0, 3, or 8 Gy) them to determine the role of the host microbiome on biofluid radiation signatures (3 d serum). |

Treatment Summary: | We used 8 week old male and female C57BL/6 mice that were purchased from Charles River Laboratories (Frederick, MD) and were assigned to sham, 3 Gy, or 8 Gy cohorts. A control group (Abx-con) did not receive antibiotics in drinking water and a treatment group (Abx) received broad-spectrum antibiotics (n=10 per group, half male half female) (S1 Fig). Mice were provided with deionized water ad libitum either with or without the antibiotic cocktail (enrofloxacin [0.575 mg/ml] and ampicillin [1 mg/ml]) for 8 days prior to irradiation [24]. Mice were irradiated in an acrylic, 12-slot mouse pie cage (MPC-1, Braintree Scientific, Braintree, MA) on top of a specimen turntable (XD1905-0000, Precision X-Ray Inc, Branford, CT) and 0, 3 or 8 Gy X-ray irradiated (1.67 Gy/min; X-Rad 320, Precision X-Ray Inc.; filter, 0.75 mm tin/ 0.25 mm copper/1.5 mm aluminum). For Abx-con mice, spot urines (>100 µL) were collected 1 d prior to irradiation and at 1 and 3 d post-irradiation (fecal samples collected 1 d prior to irradiation and at 3 d post-irradiation). |
