Transcriptomic analysis of spleens from mice subjected to chronic low-dose radiation hindlimb unloading or a combination of both

The purpose of this study was to evaluate transcriptional changes in mouse spleens using a ground-based model for spaceflight. This model includes prolonged unloading and low-dose irradiation. Low-dose-rate gamma-radiation was delivered to 6-month old female C57BL/6J mice using 57Co plates (0.04 Gy) to simulate the radiation environment of spaceflight. Anti-orthostatic tail suspension was used to model the unloading fluid shift and physiological stress aspects of the microgravity component of spaceflight. Mice were hindlimb suspended and/or irradiated for 21 days. Mice were euthanized and spleens collected 7 days following treatment. RNA sequencing data was generated to assess transcriptional changes in these spleens.
