Additionally, IHC staining revealed that the average ACAA1 staining score was significantly lower in NPC tissues (average staining score:4.28, n = 125) when compared to NNE (average staining score: 6.21, n = 14) (Figure 1F and G, p < 0.0001). This evidence concerns the gene ACAA1 and nasopharyngeal carcinoma.
