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. 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.
