Specifically, the miR-200b-3p/p38IP pair regulates monocyte/macrophage differentiation (Yu et al., 2016), miR-200b-3p in plasma may be a potential diagnostic biomarker of oral squamous cell carcinoma (Sun et al., 2018), and quercetin-induced miR-200b-3p can regulate the mode of self-renewal divisions in pancreatic cancer (Nwaeburu et al., 2017). This evidence concerns the gene SUPT20H and oral cavity squamous cell carcinoma.
