However  mounting evidence points to torpor induced protective benefits from the main hazards of space travel  namely  exposure to radiation and microgravity. To determine the radio protective effects of an induced torpor like state we exploited the ectothermic nature of the Danio rerio zebrafish in reducing their body temperatures to replicate the hypothermic states seen during natural torpor. We also administered melatonin as a sedative to reduce physical activity. Zebrafish were then exposed to low dose radiation 0.3Gy to simulate radiation exposure on long term space missions. Transcriptomic analysis found that radiation exposure led to an upregulation of inflammatory and immune signatures and a differentiation and regeneration phenotype driven by STAT3 and MYOD1 transcription factors. In addition  DNA repair processes were downregulated in the muscle two days' post irradiation. The effects of hypothermia led to an increase in mitochondrial translation including genes involved in oxidative phosphorylation and a downregulation of ex tracellular matrix and developmental genes. Upon radiation exposure  increases in endoplasmic reticulum stress genes were observed in a torpor+radiation group with downregulation of im mune related and ECM genes. Exposing hypothermic zebrafish to radiation also resulted in a downregulation of ECM and developmental genes however  immune/inflammatory related pathways were downregulated in contrast to that observed in the radiation only group. A cross species comparison was performed with the muscle of hibernating Ursus arctos horribilis brown bear to define shared mechanisms of cold tolerance. Shared responses show an upregula tion of protein translation and metabolism of amino acids  as well as a hypoxia response with the shared downregulation of glycolysis  ECM  and developmental genes.
