Thyroid cancer 1 (TC1, C8orf4) plays important roles in tumors. The aim of this study was to examine the protein expression levels, methylation status, and mutational status of TC1 (C8orf4) in lung cancers, and investigate the correlation between TC1, other members of the Wnt signaling pathway, and lung cancer. TC1 expression levels were assessed via immunohistochemical staining in 179 cases of lung cancer. β-catenin, TCF4, Axin, Disabled-2, Chibby, and DNA methyltransferase-1 (DNMT1) expressions were also examined...

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...

Sex-related systemic status of pituitary and thyroid hormones and cortisol was studied in rats on days 7 and 14 after transplantation of sarcoma C-45 cells into the lung. Females demonstrated slower development of the tumor process (49.0±10.7 vs. 32.0±3.9 days in males). Injection of tumor cells causes similar disorders in the levels of ACTH, thyrotropic hormone, and prolactin in males and females and opposite disorders in the thyroid and glucocorticoid homeostasis associated in males (in contrast to females) with reduction of cortisol level (by 1...

Complement component 1q subcomponent binding protein (C1QBP) is a ubiquitously expressed cellular protein and can be upregulated or activated in a variety of malignant tumors, including those from thyroid, colon and breast, but its role remains unclear in renal cell carcinoma (RCC). In this study, C1QBP knockdown in RCC cell influenced expression of multiple genes associated with cell adhesion, among which L1 cell adhesion molecule (L1CAM) was significantly higher upon a reduction of C1QBP. In turn, cell adhesion and invasion abilities were significantly increased with increased metastasis to lung and liver in vivo...

Importance: Incidental thyroid nodules are defined as nodules originally detected in a patient with no thyroid-related clinical symptoms, examination findings, or suspected thyroid disease. Medical imaging for diseases in the neck, chest, and spine is a common source of incidental thyroid nodules. They are easily detected but poorly characterized. The next step is to decide whether the incidental thyroid nodule should be further evaluated with ultrasonography. Observations: Indiscriminate workup of incidental thyroid nodules with ultrasonography is not cost-effective and is potentially harmful...

PURPOSE: Thyroid cancer is the most common endocrine malignancy worldwide. The molecular mechanisms underlying thyroid tumorigenesis remain unclear. Some studies suggested that the ZCCHC12 gene correlates with certain diseases. However, the function of ZCCHC12 in thyroid cancer has yet to be determined. This study investigated the role of the ZCCHC12 gene in papillary thyroid cancer (PTC). METHODS: We conducted a comprehensive analysis of massively parallel whole-transcriptome resequencing of matched PTC tumors and normal tissues in 19 patients...

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...

Neurofibromatosis type II (NF2) is a genetic disease characterized by bilateral vestibular schwannomas (VS) and other nerve system tumors. However, such tumors may be associated with environmental, rather than a genetic, etiology. Individuals fulfilling the clinical criteria of NF2 who had been treated by head ionized irradiation at a young age were compared for disease characteristics and molecular analysis with non-irradiated sporadic NF2 cases. In the study cohort, three of 33 sporadic adult cases fulfilling NF2 diagnostic criteria had a history of early age cranial irradiation exposure...

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...

Thirteen cases of invasive solid papillary breast carcinomas resembling the tall cell variant of papillary thyroid neoplasms (BPTC) are reported here. Some cases had long-term follow-up. BPTC is a special type of primary breast neoplasm showing a triple-negative profile but low aggressive potential. Knowledge on BPTC is still scanty; therefore, the aim of the present paper was to report on the features of an additional 13 cases. All the patients were female individuals, and the mean age at presentation was 62...

Pre-surgical diffusion weighted imaging (DWI) is increasingly important in the context of thyroid cancer for identification of the optimal treatment strategy. It has exemplarily been shown that DWI at 3T can distinguish undifferentiated from well-differentiated thyroid carcinoma, which has decisive implications for the magnitude of surgery. This study used DWI histogram analysis of whole tumor apparent diffusion coefficient (ADC) maps. The primary aim was to discriminate thyroid carcinomas which had already gained the capacity to metastasize lymphatically from those not yet being able to spread via the lymphatic system...

For locally advanced laryngeal cancers, the standard treatment of choice is chemoradiotherapy if organ function needs to be conserved. Surgical treatment with larynx preservation is conducted only for limited cases. For locally advanced laryngeal cancers such as those with vocal cord fixation and/or cricoid cartilage destruction, there is no apparent standardized organ-preserving surgery keeping the essential laryngeal functions, viz. the airway, deglutition and articulation, uncompromized. Recently, our surgical team saw a patient with T4a advanced laryngeal cancer with vocal cord fixation who aspired to maintain his laryngeal function...

BACKGROUND: Expression of IL-8 and its receptors CXCR1 and CXCR2 is a common occurrence in human epithelial thyroid cancer (TC). In human TC samples, IL-8 expression is associated with tumor progression. IL-8 enhances proliferation, survival, motility, and leads to the maintenance of stemness features and tumor-initiating ability of TC cells. Here, we studied the effects of Reparixin (formerly Repertaxin), a small molecular weight CXCR1 and CXCR2 inhibitor, on the malignant phenotype of various TC cell lines...
