Panel A: Summary of genes and miRNAs biomarkers studied in different animal models. The genes or miRNAs studied in different animal models such as baboons, human, mouse, and NHP were compared. Panel B: Statistics of radiation countermeasures, their classification, and experimental studies in different animal models. The drugs studied in animal models e.g., NHP, human, mouse/rat, and minipig were compared to identify unique and common ones in each model.
