Dysregulation of selected tsRNAs in NPC by qRT-PCR. We selected 10 tsRNAs dysregulated in NPC for custom qRT-PCR. (A) Expression of 5 tsRNAs upregulated in NPC. (B) Expression of 5 tsRNAs downregulated in NPC as well. All data were analyzed using Student’s t-test (*p < 0.05, **p < 0.01). ROC curve analysis of (C) tRF-1:28-Val-CAC-2, (D) tRF-1:24-Ser-CGA-1-M3, and (E) tRF-55:76-Arg-ACG-1-M2. (F) Examples of tRNA or pre-tRNA structures of the three validated tsRNAs were depicted. The red nucleotides indicate the presence of the three validated tsRNA sequences.
