FOXD3 and nasopharyngeal carcinoma: In our study, we have found the unusual expression of FOXD3-AS1 in NPC tissues through bioinformatics analysis of GSE61218 and GSE 126683, which is consistent with other datasets (BioProject: PRJNA451367 and GSE64634) in previous studies (18, 34) and demonstrated it in NPC cells and tissues.
