Ectopic thyroid tissue results from abnormal embryologic development and migration of the thyroid gland. True malignant transformation in ectopic thyroid tissue is extremely rare and is always diagnosed after surgical excision of the lesion by pathology examinations. There are well-documented cases of ectopic thyroid cancer while primary tumoral lesion occurs in the orthotopic thyroid, but only...

In the Drosophila ovary, hedgehog (hh) signaling from cells near the apical tip of the germarium stimulates the proliferation and specification of somatic cells in region 2 of the germarium, 2-5 cells away from the hh-expressing cells (A. J. Forbes, H. Lin, P. Ingham and A. Spradling (1996) Development 122, 1125-1135). This report examines the role during early oogenesis of several genes that a...

Abstract Background In cases of papillary thyroid carcinoma (PTC), lymph nodes are a typical site metastasis. Extrathyroidal tissue involvement in differentiated causes the disease to progress and affects patients’ treatment options. Papillary (PTC) is common type (DTC), other follicular (FTC). Ectopic sites, such as intrathyroidal node invasion classical malignancy, extremely uncommon. It can ...

Ectopic thyroid glands generally occur in the midline as a result of abnormal median migration, and their presence lateral to the midline is rare. We present one case of an ectopic thyroid gland masquerading as a lateral neck metastasis of a papillary thyroid carcinoma (PTC). In this case of a 54-yr-old woman with left PTC, we suspected left lateral neck metastasis on preoperative neck computed...

Thyroid cancer is the most common tumour of the endocrine system, and its incidence rate has markedly increased over the past several decades. Aberrantly expressed microRNAs (miRNAs) are reportedly involved in the formation and progression of papillary thyroid carcinoma (PTC) by regulating their target genes. Thus, miRNAs may be potential molecular biomarkers for the prediction and prognosis of...

Papillary Thyroid Carcinoma (PTC) is the most frequent thyroid cancer. Although several PTC-specific miRNA profiles have been reported, only few upregulated miRNAs are broadly recognized, while less consistent data are available about downregulated miRNAs. In this study we investigated miRNA deregulation in PTC by miRNA microarray, analysis of a public dataset from The Cancer Genome Atlas (TCGA...

Papillary thyroid carcinoma (PTC), the most common histological subtype of thyroid cancer, accounts for between 80 and 90% of all thyroid cancer cases. Previous studies have suggested that microRNAs (miRNAs/miRs) are involved in the development of PTC. The aim of the present study was to investigate whether miR-144 inhibits cellular proliferation in PTC. The expression of miR-144 was detected i...

Ventral cell fates in the central nervous system are induced by Sonic hedgehog, a homolog ofhedgehog, a secreted Drosophila protein. In the central nervous system, Sonic hedgehog has been identified as the signal inducing floor plate, motor neurons, and dopaminergic neurons. Sonic hedgehog is also involved in the induction of ventral cell type in the developing somites. ptc is a key gene in the...

Solute carrier family members control essential physiological functions and are tightly linked to human diseases. Solute carrier family 35 member F2 (SLC35F2) is aberrantly activated in several malignancies. However, the biological function and molecular mechanism of SLC35F2 in papillary thyroid carcinoma (PTC) are yet to be fully explored. Here, we showed that SLC35F2 was prominently upregulat...
