Radiation-induced oral mucositis (RIOM) is considered to be one of the most important public health problems today, affecting the overall well-being of millions of patients who have received radiotherapy. Nevertheless, the field of preventing and treating RIOM is still widely unexplored. Curcumin (Cur) with its promising anti-inflammatory and antioxidant properties is accompanied with obstacles in application, including poor dissolubility, instability and low bioavailability. In this study, a tetrahedral framework nucleic acid drug delivery system (TFNAS) was synthesized and established using a novel method to carry Cur (Cur-TFNAS) for efficient drug delivery. The results showed that Cur-TFNAS enhanced the antioxidant capacity of human oral mucosal keratin-forming cells (HOKs) compared to free Cur and TFNAS. Meanwhile, Cur-TFNAS reduced DNA damage and shielded the cells from inflammatory factors. A similar result was also well documented in vivo . Herein, we consider that Cur-TFNAS acts as a nano-shield for preventing radiation oral mucositis and shows important clinical value in the future.
