2. Wnt3a but not CDX-2 expression is associated with differentiated thyroid cancer
SUMMARY OBJECTIVE: Thyroid neoplasm incidence has increased worldwide, mostly due to the advancements in medical imaging and screening rates. The aberrant Wnt/β-catenin pathway has been identified as a key mechanism, and it has also been related to the metastatic activity of differentiated thyroid cancer. We aimed to verify the difference in the expression
