PRF1 and head and neck squamous cell carcinoma: Interestingly, in the ceRNA network, miR-3065-3p and the lncRNAs CXCR2P1, HNRNPA1P21, CTA-384D8.36, and IGHV1OR15-2 were significantly correlated with OS in HNSCC patients in the TCGA database; the relevant interactions within the network include the following: miR-3065-3p/IL2RA; CXCR2P1/miR-210-3p/FOXP3; HNRNPA1P21/miR-767-5p/IL10RA; CTA-384D8.36/miR-149-5p/STAT5A; CTA-384D8.36/miR-149-5p/PRF1; and IGHV1OR15-2/miR-744-3p/IL2RA.
