Valproic acid alleviates total-body irradiation-induced small intestinal mucositis in mice

Gastrointestinal (GI) injury is one of the serious problems of total-body irradiation (TBI). However, no fundamental treatment for TBI and other radiation-induced GI injury has yet been established. Valproic acid (VPA) administration reduces mortality in mice subjected to total-body irradiation (TBI) with X-rays. This study aimed to evaluate the effects of VPA on GI injury induced by TBI in mice.
