A method of protecting a subject against an agent that elicits production of toxic free radicals, superoxide anions, or heavy metal cations in the subject consisting of the in vivo administration to the subject of a polynucleotide encoding a protein that is transiently expressed in said subject. The transiently expressed protein is capable of neutralizing or eliminating the toxic free radicals, superoxide anions or heavy metal cations that are elicited by the agent. This method is particularly useful in protecting cancer patients against the damaging effects of ionizing radiation and chemotherapeutic drugs.
