Low dose (0.04 Gy) irradiation (LDR) and hindlimb unloading (HLU) microgravity in mice: retina transcriptomic and epigenomic data
The purpose of the present study was to evaluate damage in brain and eye in a ground-based model for spaceflight which includes prolonged unloading and low-dose radiation. Low-dose/Low-dose-rate (LDR) gamma-radiation using 57Co plates (0.04 Gy) was delivered whole-body to mature 6-month old female C57BL/6 mice to simulate the radiation component. Anti-orthostatic tail suspension was used to model the unloading fluid shift and physiological stress aspects of the microgravity component. Mice were hindlimb suspended and/or irradiated for 21 days. Tissues were collected at 7 days 1 and 4 months following simulated microgravity. Herein we proposed to use omics-based molecular phenotyping approach for identification and characterization of genomic signatures in multiple organ system associated with low-dose radiation and simulated microgravity.
