Attenuation of oxidative damage and inflammatory responses by apigenin given to mice after irradiation

► We determined the mitigative effects of apigenin given to mice after irradiation. ► A reduction in oxidative damage was found in irradiated mice receiving apigenin. ► Suppression of activated NF-κB was also found in irradiated mice receiving apigenin. ► Further, the data showed that apigenin ameliorated lymphocyte suppression. ► Hence, the beneficial effects of apigenin given after irradiation are uncovered.
