Human telomerase reverse transcriptase (hTERT) gene expression in thyroid neoplasms.
Ten percent of fine-needle aspirations (FNAs) of the thyroid are deemed "indeterminate" or "suspicious" for malignancy by the cytopathologist, but most of these lesions are benign. Therefore, additional markers of malignancy may prove to be a useful adjunct. The catalytic component of telomerase, human telomerase reverse transcriptase (hTERT), has been found to be reactivated in immortalized ce...
متن کاملExpression of thyroid-specific transcription factors TTF-1 and PAX-8 in human thyroid neoplasms.
TTF-1 and PAX-8 are tissue-specific transcription factors expressed in the thyroid follicular cells, contributing to the maintenance of the differentiated phenotype. In fact, it has been demonstrated that TTF-1 and PAX-8 are able to activate transcription from thyroglobulin and thyroperoxidase (TPO) promoters, the transcriptional activity of which is in vivo restricted only to the thyroid folli...
متن کاملInactivation of the retinoblastoma gene in human lymphoid neoplasms.
The absence of wild type retinoblastoma (Rb) gene expression in a wide variety of human solid tumors suggests an etiologic role for this tumor suppressor gene in human cancer. We have evaluated the involvement of Rb gene inactivation in the pathogenesis and progression of human lymphoma and leukemia. We examined the genomic configuration and transcription of the Rb gene in cultured cell lines a...
متن کاملHorner's syndrome and thyroid neoplasms.
Although thyroid goiter is a common condition, it rarely results in Horner's syndrome. We report a case of a patient with an intrathoracic multinodular goiter complicated by Horner's syndrome. Benign thyroid disease was confirmed pathologically, and the patient's symptoms improved after surgery. In the literature, the major cause of Horner's syndrome is neoplasia, with malignant lesions being t...
متن کاملNDRG1 protein overexpression in malignant thyroid neoplasms
OBJECTIVES The aim of this study was to examine the expression of the N-myc downstream-regulated gene 1 protein in benign and malignant lesions of the thyroid gland by immunohistochemistry. INTRODUCTION N-myc downstream-regulated gene 1 encodes a protein whose expression is induced by various stimuli, including cell differentiation, exposure to heavy metals, hypoxia, and DNA damage. Increased...
