A Amplification alteration of the APEX1 gene in thyroid cancer and normal tissue samples from The Cancer Genome Atlas (TCGA) database. B Real-time PCR detection of the mRNA expression level of Ref-1 in tumor and normal tissue samples from 16 patients. C Western blot detection of the protein expression level of Ref-1 in tumor and normal tissue specimens from 8 patients. D Representative immunohistochemical staining for Ref-1 in PTC specimens. E Percentages of samples with different BRAF mutation statuses and specific Ref-1 expression levels among 178 PTC cases. F RFS analysis of groups based on the high and low expression of Ref-1 among 178 PTC cases. *P < 0.05, **P < 0.01.
