NPC1 and nasopharyngeal carcinoma: Furthermore, TUNEL staining further demonstrated that miR‐874‐3p overexpression inhibited NPC apoptosis in the miR‐874‐3p‐treated rats, whereas miR‐874‐3p knockdown enhanced NPC apoptosis in the miR‐874‐3p inhibitor‐treated rats (Figure 7C), suggesting that the miR‐874‐3p overexpression has a protective effect against IVDD.
