Human thyroid adenomas, carcinomas, and normals


ABSTRACT: Human samples of various thyroid carcinomas, adenomas, and normals, each from a different patient, had mRNA assays performed using Affymetrix HG_U133A arrays, with 22283 probe-sets. The 99 samples consisted of 4 normals, 10 follicular adenomas, 13 follicular carcinomas, 7 oncocytic adenomas, 8 oncocytic carcinomas, 51 papillary carcinomas (each typed as having classical, follicular or tall cell morphology), 4 anaplastic carcinomas, and 2 medullary carcinomas. Interesting additional information on common mutations are provided including RAS mutation, BRAF mutation, RET/PTC rearrangements, and PAX8/PPARG translocations. Details of those assays are provided in our linked publications, as well as additional details on the specific mutations in a few special cases. No survival data is provided. Information for 93 of the 99 samples was previously made available on the web. The anaplastic and medullary carcinoma data were not previously shared. A supplementary Excel spreadsheet holding the same processed data as the series matrix file is provided and is more compact. The raw (.CEL) files are also provided.

A subset of follicular thyroid carcinomas contains a balanced translocation, t(2;3)(q13;p25), that results in fusion of the paired box gene 8 (PAX8) and peroxisome proliferator-activated receptor gamma (PPARG) genes with concomitant expression of a PAX8-PPARgamma fusion protein, PPFP. PPFP is thought to contribute to neoplasia through a mechanism in which it acts as a dominant-negative inhibitor of wild-type PPARgamma. To better understand this type of follicular carcinoma, we generated global g  ...[more]
