| Study Title | The gut microbiome has sexually dimorphic effects on bone tissue energy metabolism and multiscale bone quality in C57BL/6J mice |
| Study Summary | Male and female germ-free and conventional were euthanized at 20 weeks of age, and various tissues were obtained to assess differences in bone properties associated with microbiome status and sex. For metabolomic analyses, the humeri was obtained, bone marrow was flushed using PBS, and subchondral bone metabolites were extracted using a methanol:acetone precipitation approach. Next, samples were injected, ionized, and data was acquired using LC-MS. Data was processed and converted using MSConvert and XCMS. Following this step, metabolic phenotypes of mice that differ by microbiome status and sex were investigated using MetaboAnalyst. Differences in metabolism were related to lipid, energy, and amino acid metabolism. Specifically, females, both conventional and germ-free, had dysregulated lipid metabolism, whereas, males, both conventional and germ-free had dysregulated amino acid metabolism. Other differences detected between male and female mice that differ by germ-free status corresponded to differences in bone strength, bone marrow adiposity, and osteocyte density. |

Sample Preparation:
| Sampleprep ID: | SP002437 |
| Sampleprep Summary: | Once euthanized, tissues were dissected and harvested for various techniques. For metabolomics, humeri samples underwent homogenization/crushing, extracted with methanol:acetone, and were then subjected to rounds of vortexing and centrifugation. Once metabolites were isolated, samples were dried via vacuum concentration and resuspended with acetonitrile:water for LC-MS analysis. |
