Project description:Papillary thyroid carcinoma (PTC) is the most common malignant phenotype of thyroid cancer, with a rapidly increasing number of new cases globally. Multifocality is a common phenomenon in patients with PTC. The tumor microenvironment (TME) plays a pivotal role in cancer progression in papillary thyroid carcinoma (PTC), yet the composition and phenotype of cells within TME in bilateral PTCs are poorly understood.
Project description:RNA-Sequencing analysis of 18 papillary thyroid carcinoma biopsies and of 4 healthy donors' thyroids. In this analysis we assessed differential gene expression and investigated the mutational landscape in this tumor type. Analysis of gene fusion was also performed, leading to the identification of a novel chimeric transcript, potential driver in tumor initiation. Total RNA isolated from 18 papillary thyroid carcinoma biopsies and 4 healthy donors' thyroids.
Project description:Long noncoding RNAs (lncRNAs) have been proved to play important roles in cancer biology. To understand their expression profile and potential functions in papillary thyroid carcinoma (PTC), we investigated the lncRNA and mRNA expression in PTC and paired adjacent noncancerous thyroid tissues using microarray analysis.
Project description:Although most thyroid tumours are benign, thyroid cancer represents the most common malignancy of the endocrine system, comprising mainly follicular and papillary thyroid carcinomas (FTC and PTC, respectively). Previous studies have shed some light on the molecular pathogenesis of thyroid cancer but there have not been any comprehensive mass spectrometry-based proteomic studies to reveal protein expression differences between thyroid tumours and the molecular alterations associated with tumour malignancy. We applied a label-free quantitative mass spectrometry analysis to compare normal thyroid tissue with the three most common tumours of the thyroid gland: follicular adenoma, follicular carcinoma and papillary carcinoma.
Project description:We tried to analyze the effect of FTO on papillary thyroid carcinoma. We constructed a FTO overexpression stable cell line of papillary thyroid carcinoma cells. We performed meRIP-seq sequencing analysis of the FTO overexpression stable transfer cell line to try to assess which genes were changed at the m6A level in papillary thyroid cancer cells by overexpressing FTO.

Project description:CircRNA deregulation could be a crucial event in thyroid carcinoma. To investigate circRNA signatures present in several papillary thyroid carcinoma (PTC) patients to complement our understanding of PTC pathogenesis. Using microarray technology, we screened the circRNA profiles in 3 pairs of PTC tumors and matching adjacent normal tissues. This study evaluated circRNAs expression profiles and their ability to serve as reliable biomarkers and new potential diagnostic and therapeutic targets for PTC
Project description:Paillary thyroid cancer (PTC) is the most common type of thyroid malignancy. Extrathyroidal invasion (ETİ), lymph node metastasis, and distance organ metastasis is poor prognostic factor in PTC. The metastasis is still a leading cause of papillary thyroid cancer death. The early detection of metastatic signature is crucial for identification of thyroid cancer prognosis and personalized therapeutic strategies. In the present study, we present thyroid cancer metastasis and invasivenes related miRNAs identified by comprehensive miRNA expression profiling of formalin-fixed paraffin embedded (FFPE) thyroid tissues obtained from patients belonging to intrathyroidal, invasive and metastatic thyroid carcinoma groups
Project description:Here we have performed quantitative and qualitative profiling of the proteome of cystic fluid from human cystic papillary thyroid carcinoma with the aim to identify specific proteins and pathways involved in cystic fluid from human cystic papillary carcinoma, as well as possible diagnostic markers.
Project description:Thyroid nodules occur in about 60% of the population. Current diagnostic strategies, however, often fail at distinguishing malignant nodules before surgery, thus leading to unnecessary, invasive treatments. As proteins are involved in all physio/pathological processes, a proteome investigation of biopsied nodules may help correctly classify and identify malignant nodules and discover therapeutic targets. Quantitative mass spectrometry data-independent acquisition (DIA) enables highly reproducible and rapid throughput investigation of proteomes. An exhaustive spectral library of thyroid nodules is essential for DIA yet still unavailable. This study presents a comprehensive thyroid spectral library covering five types of thyroid tissue: multinodular goiter, follicular adenoma, follicular and papillary thyroid carcinoma, and normal thyroid tissue. Our library includes 925,330 transition groups, 157,548 peptide precursors, 121,960 peptides, 9941 protein groups, and 9826 proteins from proteotypic peptides. This library resource was evaluated using three papillary thyroid carcinoma samples and their corresponding adjacent normal thyroid tissue, leading to effective quantification of up to 7863 proteins from biopsy-level thyroid tissues.
