Comparative Evaluation of Cyclin D1 Protein Expression in Papillary Thyroid Carcinoma and Follicular Epithelial Dysplasia Associated with Hashimoto’s Thyroiditis
Background: Hashimoto’s thyroiditis (HT) is a common autoimmune disease characterized by chronic inflammation of the thyroid gland. Cyclin D1, a key regulator of cell-cycle progression implicated in multiple malignancies, may also contribute to the pathogenesis of thyroid lesions. Objectives: This study aimed to evalua...
