Rare thyroid non-neoplastic diseases
Rare diseases are usually defined as entities affecting less than 1 person per 2,000. About 7,000 different rare entities are distinguished and, among them, rare diseases of the thyroid gland. Although not frequent, they can be found in the everyday practice of endocrinologists and should be considered in differential diagnosis. Rare non-neoplastic thyroid diseases will be discussed. Congenital...
متن کاملFRA-1 expression in hyperplastic and neoplastic thyroid diseases.
fra-1 gene overexpression has been shown to represent a general event in thyroid cell transformation in vitro and in vivo. Moreover, inhibition of FRA-1 protein synthesis by stable transfection with a fra-1 antisense construct significantly reduces the malignant phenotype of the transformed thyroid cells, indicating a pivotal role of the fra-1 gene product in the process of cellular transformat...
متن کاملDiagnostic Value of RAS Mutations in Indeterminate Thyroid Nodules.
Objectives To determine the diagnostic value of HRAS, KRAS, and NRAS mutations in fine-needle aspiration biopsies of thyroid nodules that are nondiagnostic on cytology. Data Sources PubMed, Scopus, Embase, CINAHL. Review Methods Two authors independently searched the data sources. To be included, studies reported the RAS mutational status and postoperative histopathologic diagnosis of nodules t...
متن کاملRoles of RAS and BRAF mutations in thyroid carcinogenesis.
Papillary carcinoma and follicular carcinoma are types of differentiated thyroid carcinomas, develop from the same thyroid follicular epithelial cells and show distinct biological behavior. Although several studies have demonstrated differences in the biological characteristics of these carcinomas, little is known about the genetic backgrounds that underlie these differences. The clarification ...
متن کاملDetection of N-, H-, and KRAS codons 12, 13, and 61 mutations with universal RAS primer multiplex PCR and N-, H-, and KRAS-specific primer extension.
OBJECTIVES Mutations of all three RAS genes, N-, H-, and KRAS, are identified mainly in codons 12, 13, and 61 of exons 2 and 3 in human cancers. DESIGN AND METHODS DNA samples were isolated from 58 oral cancer and 106 colorectal cancer patients. Multiplex amplification of codons 12 and 13 of exon 2 and codon 61 of exon 3 of three RAS genes using two pairs of universal primers for exons 2 and ...
