CASC19 and nasopharyngeal carcinoma: Taken together, this study presented the comprehensive analysis of the lncRNA, miRNA, and mRNA expression profiles between radioresistance and radiosensitive NPC cells and built a novel ceRNA regulatory network, CASC19/miR-340-3p/FKBP5, as a key player in modulating the radiosensitivity of NPC cells by promoting autophagy (Figure 7).
