Role of oncogene PIM-1 in the development and progression of papillary thyroid carcinoma: Involvement of oxidative stress.

In this study, we aimed to clarify the role of PIM-1 in papillary thyroid carcinoma (PTC) in vitro and investigate the relationship between PIM-1 and redox proteins (NOX4, SOD2, and GPX2) at the tissue and cellular levels. As a PIM-1 inhibitor, SGI-1776 inhibited cell proliferation, colony formation, migration and induced an increase in apoptosis and reactive oxygen species in two PTC cell lines (BCPAP and TPC-1). The expressions of PIM-1, SOD2 and GPX2 were downregulated after siNOX4 exposure.

Predictive Risk-scoring Model For Central Lymph Node Metastasis and Predictors of Recurrence in Papillary Thyroid Carcinoma.

There are about half of papillary thyroid carcinoma (PTC) patients with the experience of central lymph node metastasis (CLNM), while the model to predict high-risk groups of CLNM from PTC patients is uncertain. The aim of this study was to evaluate candidate risk factors of CLNM and identify risk factors of recurrence to guide the postoperative therapeutic decision and follow-up for physicians and patients.A total of 4107 patients(4884 lesions) who underwent lymph node dissection in two hospitals from 2005 to 2014 were evaluated.

Diagnostic values of thyroglobulin in lymph node fine-needle aspiration washout: a systematic review and meta-analysis diagnostic values of FNA-Tg.

Thyroglobulin measurement in the needle washout after fine-needle aspiration (FNA-Tg) served as an important measurement for suspicious recurrent or metastatic lesions. We conducted a pooled analysis to evaluate the diagnostic accuracy of FNA-Tg and searched electronic databases for original articles in English from 1993 through 2017. Finally, a total of 22 studies containing 2,670 lymph nodes (LNs) that enrolled participants with suspicious neck LNs during thyroid nodule workup or papillary thyroid cancer (PTC) follow-up were included.

Expression and prognostic significance of MCM-3 and MCM-7 in salivary adenoid cystic carcinoma.

This study sought to investigate minichromosome maintenance protein 3 (MCM3) and minichromosome maintenance protein 7 (MCM7) expression in salivary adenoid cystic carcinoma (SACC) samples, and to evaluate the relationship between clinicopathological characteristics and prognosis. The expressions of MCM3 and MCM7 were evaluated using immunohistochemistry of tissue sections from SACC patients, and statistical analyses were performed to evaluate the associations between MCM expression and clinicopathological variables and to analyze the disease-free survival (DFS) and prognostic factors. The positive expression rates of MCM3 and MCM7 in SACC were 98.

Preliminary screening and analysis of metastasis-related lncRNA and co-expressed papillary thyroid carcinoma mRNA.

The objective of the present study was to investigate the long non-coding RNA (lncRNA) and mRNA expression profiles that are associated with the invasion and metastasis of papillary thyroid carcinoma (PTC). Transwell invasion assays were used to screen three highly invasive sub-strains of the human PTC IHH4 cell line: IHH4-M1, IHH4-M2 and IHH4-M3. In addition, tumor-bearing nude mice were used to identify the invasive and metastatic capacity of the three sub-strains.

Nomograms predicting disease-specific regional recurrence and distant recurrence of papillary thyroid carcinoma following partial or total thyroidectomy.

The study aimed to establish effective nomograms for prediction of tumor regional recurrence and distant recurrence of papillary thyroid carcinoma (PTC) patients after partial or total thyroidectomy.These nomograms were based on a retrospective study on 1034 patients who underwent partial or total thyroidectomy for PTC. The predictive accuracy and discriminative ability of the nomograms were evaluated by the concordance index (C-index) and calibration curve.
