To determine whether the SNP rs117565607 (A/T) was involved in the transcriptional regulation of TRIM26 in NPC, we firstly divided 108 clinical NPC samples into two groups according to the SNP genotype of rs117565607 and observed that TRIM26 was significantly downregulated in NPC tissue samples with genotype AA/AT (genotype based on sense strand of the sequence) than TT (Figure 3B). This evidence concerns the gene TRIM26 and nasopharyngeal carcinoma.
