To dissect the miR‐BARTs expression levels in the 20 available NPC biopsies, in which the BRCA1 protein expression status was studied in IHC, we revealed that the total expressions of BART2‐3p, BART12, BART17‐5p and BART19‐3p in BRCA1‐positive NPCs (n = 7) were significantly lower than in BRCA1‐negative NPCs (n = 13) (P = 0.039) (Figure 1E). The gene discussed is BRCA1; the disease is nasopharyngeal carcinoma.
