A critical issue for radiation countermeasure development is the limited number of animal models suitable for countermeasure testing under the FDA Animal Rule. We are characterizing the minipig as an additional large-animal model for advanced drug testing for the Acute Radiation Syndrome (ARS). Our previous work has shown that the minipig is a suitable model for longitudinal blood sampling in irradiated, immunocompromised animals, and that the hematopoietic sub-syndrome of the ARS closely mimics that in humans in terms of clinical signs, symptoms and kinetics of blood cell depletion and recovery.
Administration of G-CSF, the standard cytokine treatment for radiation injury, provided protection and hematological recovery as expected from other models. Utility of the minipig for ex vivo and in vivo biodosimetric studies was confirmed by the similarity in response between human and porcine samples of gamma-H2AX, a surrogate marker for double-strand breaks and a potential tool for quickly assessing exposure to radiation.
My current research interests include understanding the pathophysiology of radiation injury and validating the minipig as a large-animal model for ARS in adult and pediatric populations, for radiation countermeasure efficacy testing.
