FOXO1 and esophageal squamous cell carcinoma: Zhang et al. reported that the lncRNA DNM3OS is highly expressed in ESCC cells and tissues and further suggested that CAFs induce the transcription of DNM3OS by activating the platelet-derived growth factor-β (PDGF-β)/platelet-derived growth factor receptor β (PDGFR-β)/forkhead box protein O1 (FOXO1) pathway.
