TP53BP1 and periodontitis: The m6A-dependent regulation of tumor protein p53 binding protein 1 (TP53BP1) mRNA by WTAP was confirmed using methylated RNA immunoprecipitation (MeRIP), RNA immunoprecipitation (RIP), and Actinomycin D (Act D) assays.<h4>Results</h4>WTAP was identified as a candidate gene that was upregulated in periodontitis gingival tissues.
