Using a post-hoc comparison for pairs of groups, we observed that HLTF expression decreased when comparing adenomas to anaplastic carcinomas (MOD: p = 0.03, Figure 3A; LI: p = 0.05, Figure 3B), adenomas to follicular carcinomas (LI: p = 0.02, Figure 3B), papillary carcinomas to follicular carcinomas (MOD: p = 0.02, Figure 2A; LI: p = 0.000003, Figure 2B) and papillary carcinomas to anaplastic carcinomas (MOD: p = 0.002, Figure 3A; LI: p = 0.00006, Figure 3B). This evidence concerns the gene HLTF and undifferentiated carcinoma.
