Several potential biomarkers of thyroid cancer have been reported, including BRAFV600E and RAS genes in papillary thyroid cancer (PTC) [3,4], paired box 8 (PAX8), peroxisome proliferator-activated receptor γ (PPARγ) fusion gene [5], loss of heterozygosity (LOH) on chromosome 3p and 7q loci, and RAS mutations in follicular thyroid cancer (FTC) [6]. Here, PAX8 is linked to thyroid gland follicular carcinoma.
