Project description:A cohort of distinct thyroid neoplasias was hybridized onto the Affymetrix U95 GeneChip We profiled the gene expression of a cohort of 9 Hurthle cell adenomas, 17 follicular adenomas, 9 follicular thyroid carcinomas, 13 follicular variants of papillary thyroid carcinomas, 6 Hashimoto throiditis, 8 thyroid hyperplasias and 9 papillary thyroid carcinomas.

Normal thyrocytes vs papillary vs anaplastic thyroid carcinomas

Project description:We profiled the gene expression of 11 anaplastic thyroid carcinomas (ATC), 49 papillary thyroid carcinomas (PTC) and 45 normal thyroids (N) We hibridized a series of anaplastic thyroid carcinomas (ATC) and papillary thyroid carcinomas (PTC) onto Affymetrix U133 Plus 2.0 arrays. 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.

Expression profiling in proliferative thyroid lesions of different histologies and normal thyroid tissue

Project description:Experiment a) Establishment of expression profiles in conventional papillary thyroid carcinomas (PTCs) with a BRAF mutation vs. PTCs without a BRAF mutation and using normal thyroid (TN) specimens as reference. Experiment b) Establishment of expression profiles in follicular adenomas (FAs) of the thyroid and follicular variant of papillary thyroid carcinomas (FVPTCs).

PIAS2b dsRNAi repression kills by mitotic catastrophe anaplastic thyroid and non-thyroid carcinomas, but not normal thyroid or differentiated carcinomas

Project description:The E3 SUMO ligase PIAS2 is expressed at high levels in differentiated papillary thyroid carcinomas but at low levels in anaplastic thyroid carcinomas (ATC), an undifferentiated cancer with very high mortality. Double-stranded RNA–directed RNA interference (dsRNAi) targeting the PIAS2 isoform beta (PIAS2b) inhibits growth of ATC cell lines and patient primary cultures in vitro and orthotopic patient-derived xenografts (oPDX) in vivo, but not of thyroid cell lines or non-anaplastic primary thyroid cultures (differentiated carcinoma, benign lesions, or normal). PIAS2b-dsRNAi also has an anti-cancer effect on other anaplastic human cancers (pancreas, lung, and gastric). Mechanistically, PIAS2b is required for proper mitotic spindle and centrosome assembly, and it is a dosage-sensitive protein in ATC. Strikingly, PIAS2b-dsRNAi induces mitotic catastrophe at prophase. High-throughput proteomics revealed the proteasome (PSMC5) and spindle cytoskeleton as direct targets of PIAS2b SUMOylation at mitotic initiation. PIAS2b-dsRNAi is a promising therapy for ATC and other aggressive anaplastic cancers.
