Trefoil factor 3 (TFF3), a regulatory protein composed of 59 amino acids, has been suggested to be involved in pathogen- esis, proliferation, invasion, migration and apoptosis in multiple malignant tumors. However, the roles of TFF3 concerning the viability, migration and invasion in papillary thyroid carcinoma cells have not yet been studied. This study aimed to investigate the effect of TFF3 knockdown on a thyroid papillary carcinoma TPC-1 cell line both in vitro and in vivo. In the present study, lentivirus-mediated short hairpin RNA (shRNA) targeting TFF3 plasmids were first constructed and stable TPC-1 cells were obtained while their TFF3 gene was silenced with either shTFF3-TPC-1, or a scrambled shRNA control...

Emerging evidence suggests that unregulated Toll-like receptors (TLRs) signaling promotes tumor survival signals, thus favoring tumor progression. Here, the mechanism underlying TLR4 overexpression in papillary thyroid carcinomas (PTCs) mainly harboring the BRAFV600E mutation was studied. TLR4 was overexpressed in PTCs compared to non-neoplastic thyroid tissue. Moreover, paired clinical specimens of primary PTC and its lymph node metastasis showed a significant upregulation of TLR4 levels in the metastatic tissues...

Papillary thyroid carcinoma (PTC) is the one of the most common types of endocrine cancer and has a heterogeneous prognosis. Tumors from patients with poor prognosis may differentially express specific genes. Therefore, an analysis of The Cancer Genome Atlas (TCGA) database was performed and revealed that cytokine receptor-like factor 1 (CRLF1) may be a potential novel target for PTC treatment. The objective of the current study was to explore the expression of CRLF1 in PTC and to investigate the main functions and mechanisms of CRLF1 in PTC...

Papillary thyroid carcinoma (PTC) is defined by an invasive growth pattern and classic nuclear features: enlarged, grooved, overlapping nuclei with chromatin clearing and intranuclear cytoplasmic pseudoinclusions (INCP). True INCPs are characteristic of PTC, but may infrequently be seen in noninvasive follicular thyroid neoplasms with papillary-like nuclear features (NIFTP). Nuclear abnormalities that mimic INCP ("pseudo-pseudoinclusions") are common in a variety of thyroid lesions. H&E and ubiquitin-stained whole tissue sections of classic PTC (n = 25) and NIFTP (n = 35) were evaluated...

Iodine has always been connected to thyroid gland, and the fact that thyroid tissue traps, organificates and stores iodine more than other tissues is well known, hence the use of radioiodine as a diagnostic and therapeutic tool for thyroid disorders. However, false-positive cases do occur. We present a case of a 34-year-old patient who underwent total thyroidectomy for papillary carcinoma. Results of follow up TSH, thyroglobulin and thyroglobulin antibody tests after surgery lead to two rounds of radioactive iodine...

The T-box transcription factor TBX3 has been implicated in the patterning and differentiation of a number of tissues during embryonic development, and is overexpressed in a variety of cancers; however, the precise function of TBX3 in papillary thyroid carcinoma (PTC) development remains to be determined. In the current study, we report downregulation of TBX3 in PTC cells delays the G1/S-phase transition, decreases cell growth in vitro, and inhibits tumor formation in vivo. We identified p57KIP2 as a novel downstream target that serves as the key mediator of TBX3's control over PTC cell proliferation...
