BRD9 and periodontitis: Inspired by above findings, to test the prevention and therapeutic potential of dBRD9 for LPS/ligation-induced acute periodontitis and alveolar bone loss, the modified injectable photocuring SF containing BRD9 degrader, was further utilized and injected into the periodontal tissue during LPS/ligation induction, with SF containing vector in the contralateral (Fig. 9h).
