Fucose residues of cell surface glycans, which play important roles in growth, invasion and metastasis, are added by fucosyltransferases (FUTs) and removed by α-L-fucosidases (FUCAs). By the differential display method, we isolated a 3' non-coding region of α-L-fucosidase-1 (FUCA1) (a gene coding for the lysosomal fucosidase-1 enzyme) as a wild-type p53-inducible gene: 18S and 20S FUCA1 mRNA species were induced in Saos-2 cells transfected with a temperature-sensitive p53 mutant at the permissive temperature...

Anaplastic thyroid cancer (ATC) is an aggressive malignancy with poor prognosis. It was reported that Forkhead box D3 (FOXD3) transcription factor is associated with several cancers. We investigated its antitumorigenic role of ATC in this study. The ATC cell lines SW1736 and K18 exhibited lower FOXD3 expression than the Nthy-ori-3-1 normal thyroid cell line. FOXD3 downregulation in ATC cell lines promoted invasiveness and epithelial-to-mesenchymal transition (EMT) and decreased cellular apoptosis. FOXD3 silencing also enhanced p-ERK levels in the ATC cell lines, suggesting it negatively regulated MAPK/ERK signaling...

In the past 2 decades, the incidence of thyroid cancer has been rapidly increasing worldwide. Anaplastic thyroid cancer (ATC) is the most lethal of all thyroid cancers and one of the most aggressive human carcinomas. SPC24 is an important component of the mitotic checkpoint machinery in the tumorigenesis and high levels of SPC24 have been found in colorectal and hepatocellular carcinomas, but its role in anaplastic thyroid cancer is still unclear. Our results showed that SPC24 was high expressed in human thyroid cancer samples...

Monoclonal antibodies that inhibit the interaction between PD1 and PD-L1 are approved for clinical use in several cancer types, and they are also in clinical trials for additional indications, including thyroid carcinomas. A few papers have reported on PD-L1 expression in thyroid carcinomas, including a recent large study by Ahn et al. in Endocrine-Related Cancer using tissue microarrays on differentiated and anaplastic thyroid carcinoma. However, the expression of PD-L1 in medullary thyroid carcinoma (MTC) has not been reported so far, even though ongoing clinical studies aim to test the effectiveness of checkpoint inhibitors in this rare histotype as well...

Glycans containing α-L-fucose participate in diverse interactions between cells and extracellular matrix. High glycan expression on cell surface is often associated with neoplastic progression. The lysosomal exoenzyme, α-L-fucosidase-1 (FUCA-1) removes fucose residues from glycans. The FUCA-1 gene is down-regulated in highly aggressive and metastatic human tumors. However, the role of FUCA-1 in tumor progression remains unclear. It is speculated that its inactivation perturbs glycosylation of proteins involved in cell adhesion and promotes cancer...

Runx2 promotes metastatic ability of cancer cells by directly activating some of the mediators regarding malignancy. Galectin-3 (Gal-3) extensively expressed in normal and transformed cells and it is responsible for many cellular processes. In this study, we aimed to investigate whether there is any relationship between runx2 transcription factor and regulation of galectin-3 expression in different human thyroid carcinoma cell lines. To show effects of runx2 transcription factor on gal-3 expression, we developed runx2 knockdown model in the thyroid carcinoma cell lines; anaplastic 8505C and 8305C and, papillary TPC-1 and follicular FTC-133 by using siRNA transfection...

The syndrome of Familial Non Medullary Thyroid Carcinoma (FNMTC) includes two or more patients with an isolated non-medullary thyroid cancer (papillary, follicular, anaplastic) within the same family. To diagnose FNMTC, the clinician must exclude a syndromic presentation such as the syndromes of Cowden, Gardner or Werner, and the Carney Complex. Up to now, a hundred families with FNMTC have been genetically studied, including forms with (Ch19p13.2) or without oxyphilia (Ch2q21), in association with a multinodular goiter (Ch14q32), or with a renal cancer (Ch1q21)...

AIM: Thyroid cancer is the most common endocrine malignancy, with an increasing incidence worldwide. Most thyroid cancers are well differentiated and have a favorable outcome. However, undifferentiated thyroid cancers are one of the most lethal human malignancies. Anaplastic thyroid cancer (ATC) accounts for 2% of all thyroid cancers, and its median survival rate is low. ATC is responsible for more than one-third of thyroid cancer-related deaths. Myricetin is a flavonol compound found in walnuts, herbs, and various berries and is known to induce apoptotic death of various types of cancer cells...

Context: Recent studies showed that transcription of the MYC gene is driven by interaction of bromodomain and extraterminal domain (BET) proteins with acetylated histones on chromatin. A potent inhibitor, JQ1, which effectively disrupts the interaction of BET proteins with acetylated histones, preferentially suppresses transcription of the MYC gene. We recently reported that JQ1 decreased thyroid tumor growth and improved survival in a mouse model of anaplastic thyroid cancer (ATC) by targeting MYC transcription...

Anaplastic carcinoma of the thyroid (ATC) is a lethal human malignant cancer with median survival of 6 months. To date, no treatment has substantially changed its course, which makes urgent need for the development of novel drugs or novel formulations for drug delivery. Nanomedicine has enormous potential to improve the accuracy of cancer therapy by enhancing availability and stability, decreasing effective doses and reducing side effects of drugs. Camptothecin (CPT) is an inhibitor of DNA topoisomerase-I with several anticancer properties but has poor solubility and a high degradation rate...

Central airway obstruction (CAO) can result from various benign and malignant etiologies. Anaplastic thyroid cancer (ATC) is the most aggressive form of thyroid cancer. Rapid airway compromise is the main cause of death in ATC. We report a patient with ATC who presented with a large neck mass leading to CAO with long segment tracheal and right main bronchial compression and respiratory failure. Urgent Rigid Bronchoscopy was performed for airway stabilization and patient was managed with a combination airway stenting approach...

Establishment and maintenance of the apical-basal cell polarity, required for proper replication, migration, specialized functions and tissue morphogenesis, relies on three evolutionary conserved complexes: PAR, CRUMBS and SCRIBBLE. Loss of cell polarity/cohesiveness (LOP/C) is implicated in cancer progression, and members of the polarity complex have been described as either oncogenes or oncosuppressors. However, no information on their role in thyroid cancer (TC) progression is available. In the present study, we evaluated the gene expression of the PAR complex members aPKCι, PARD3α/β and PARD6α/β/γ in 95 papillary TC (PTC), compared to their normal matched tissues and in 12 anaplastic TC (ATC)...
