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. |

Treatment ID: | TR002443 |
Treatment Summary: | All C57Bl/6J mice (male, female, germ-free, conventional) were housed at Montana State University. During this time, mice were kept on a light/dark cycle and fed a standard chow diet ad libitum. Upon 20 weeks of age, mice were euthanized. No additional factors such as injury, diet, or exercise occurred. Mice were employed to analyze differences in bone at macro and micro levels that are associated with the microbiome and sex. |
