RNA-Sequencing of human papillary thyroid carcinomas

ABSTRACT: 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.

Papillary thyroid carcinoma (PTC) is the most frequent thyroid malignant neoplasia. Oncogene activation occurs in more than 70% of the cases. Indeed, about 40% of PTCs harbor mutations in BRAF gene, whereas RET rearrangements (RET/PTC oncogenes) are present in about 20% of cases. Finally, RAS mutations and TRK rearrangements account for about 5% each of these malignancies. We used RNA-Sequencing to identify fusion transcripts and mutations in cancer driver genes in a cohort of 18 PTC patients. F ...[more]

ATCs were obtained from different hospitals in France and Belgium. Paired RNA samples of PTCs and non-tumoral thyroid tissues were obtained from Ukraine via the Chernobyl Tissue Bank (www.chernobyltissuebank.com). Diagnoses were confirmed by the members of the International Pathology Panel of the Chernobyl Tissue Bank.

Gene expression signature associated with BRAFV600E mutation based on transgenic mouse model (mouse)

Project description:BRAFV600E mutation is the most frequent molecular event in papillary thyroid carcinoma. The relation of this genetic alteration with the factors od poor prognosis has been reported as well as its influence on PTC gene signature. However human material disables distinction of cancer causes from its effect. We used our transgenic mouse model of papillary thyroid carcinoma induced by the BRAFV600E mutation to select BRAFV600E-specific gene signature The transgenic mouse model was obtained by the microinjection of the transgene, composed of the human BRAF cDNA with V600E mutation under the control of bovine thyroglobulin, into the ferilized mice egg cells. Three lines were derived and mice after 4-24 months were sacrificed and histopathological evaluation of thyroids was carried out. In order to find BRAFV600E-specific gene signature microarray analysis was performed. The analysis invloved 38 mice thyroid samples: 10 mice papillary thyroid carcinomas, 10 borderline lesions (all being BRAF-positive), 10 apparently asymptomatic thyroids (5 BRAF-positive and 5 BRAF-negative) and 8 benign hyperplastic lesions (4 BRAF-positive and 4 BRAF-negative). Multofactoral analyses were performed in order to define some additional factors that could have impact on the gene expression profile.

However human material disables distinction of cancer causes from its effect. We used our transgenic mouse model of papillary thyroid carcinoma induced by the BRAFV600E mutation to select BRAFV600E-specifi gene signature which was than compared to human material The human microarray data were obtained for: 27 papillary thyroid carcinomas including 18 BRAF(+), 8 RET(+), 1 RAS(+); 18 apparently healthy thyroids. In order to find BRAFV600E-specific gene signature data obtained from our transgenic mouse model of PTC were compared to human material. The analyses were performed taking into account not only the BRAF mutation but also other PTC initiating events including RET rearrangements and RAS poin mutations. Morover the microarray data were validated with the QPCR reaction.

Proteomics of thyroid tumours - Proteomics of thyroid tumours provides new insights into their molecular composition and changes associated with malignancy

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.
