Overexpression of DQ786243 was found to regulate miR-146a through Foxp3, miR-146a subsequently inhibits NF-κB signaling by blocking IL1R-associated kinase expression and tumor necrosis factor receptor-associated factor (TRAF) 6, increasing the proportion and inhibitory function of Tregs in patients with OLP (Wang et al., 2019b). This evidence concerns the gene FOXP3 and oral lichen planus.
