A fishnet between nasopharyngeal carcinoma and resistance: the competing endogenous RNA network.

Chemotherapy and radiotherapy (chemo-/radiotherapy) have advanced as the main treatment modalities for nasopharyngeal carcinoma (NPC), improving patient survival rates. However, chemo-/radiotherapy resistance in NPC cells has emerged as a key factor contributing to poor prognosis. Recently, competing endogenous RNA networks (ceRNETs) have garnered attention for their potential clinical value in studying chemo-/radiotherapy resistance. In this review, we aimed to explore the molecular mechanisms of ceRNA-related molecules, including circular RNA (circRNA), long non-coding RNA (lncRNA), microRNA (miRNA), and other competing endogenous RNAs, in regulating the chemo-/radiotherapy resistance in NPC. Additionally, we discuss the potential applications of ceRNA as a prognostic indicator and therapeutic target for this resistance.
