One of the chemoradiotherapy (CRT) side effects is oral mucositis (OM). Since photobiomodulation therapy (PBMT) is a public method for the repair process, in the present study the mechanism of PBMT in the prevention of OM is investigated via the bioinformatics approach. Six validated and significant differentially expressed genes (DEGs) associated with the prevention of OM in head and neck cancer (HNC) patients who had experienced CRT were extracted from the literature. After adding 50 neighbors from STRING, the network was constructed and analyzed. The results of the action map and network analysis were compared and discussed. HLA gene family were identified as central nodes of the analyzed network. Based on action map finding, activation is prominent action and IRF9 was the potent activator. The role of the IRF gene family was highlighted by action map analysis. Regulation of the immune system by HLA and IRF genes family is a crucial factor in the prevention of OM in the studied patients.
