PAPILLARY THYROID CARCINOMA IN MASHHAD
Thyroid cancer is the most common endocrine malignancy. This study surveys the pathologic characteristics of thyroid cancerin Mashhad and study of papillary carcinoma in more detail. In this retrospective study, 108 out of 197 cases of thyroid cancer were papillary in type (55%), with female to male ratio of 1.91 which is lower than current reports. The age at the time of diagnosis ranged ...
متن کاملMicroRNA-613 inhibits cell growth, migration and invasion of papillary thyroid carcinoma by regulating SphK2
MicroRNAs (miRNAs) have emerged as important gene regulators and are recognized as key players in carcinogenesis. In this study, we investigated the biological function and mechanism of miR-613 in the regulation of papillary thyroid cancer (PTC) development. We found that miR-613 was downregulated in PTC cell lines and tissues, and overexpression of miR-613 significantly suppressed PTC cell gro...
متن کاملExpression of Estrogen and Progesterone Receptors in Papillary Thyroid Carcinoma
Background: Papillary thyroid carcinoma (PTC), occurs mostly in women and sex hormones may play a role in the pathogenesis and clinical course. The objective of this study was to determine the status and prevalence of estrogen and progesterone receptors in PTC with regard to age, gender, tumor size and lymph node involvement. Methods: Immunohistochemical stains were performed on 92 tissue bl...
متن کاملThe role of microRNA genes in papillary thyroid carcinoma.
Apart from alterations in the RET/PTC-RAS-BRAF pathway, comparatively little is known about the genetics of papillary thyroid carcinoma (PTC). We show that numerous microRNAs (miRNAs) are transcriptionally up-regulated in PTC tumors compared with unaffected thyroid tissue. A set of five miRNAs, including the three most up-regulated ones (miR-221, -222, and -146), distinguished unequivocally bet...
متن کاملFamily of microRNA-146 Regulates RARβ in Papillary Thyroid Carcinoma
Retinoic acid is a promising tool in adjuvant cancer therapies, including refractory thyroid cancer, and its biological role is mediated by the retinoic acid receptor beta (RARβ). However, expression of RARβ is lowered in papillary thyroid carcinoma (PTC), contributing to promotion of tumor growth and inefficiency of retinoic acid and radioactive iodine treatment. The causes of aberrant RARB ex...
