PAX8-PPARgamma fusion gene expression was found in 25% (six of 24) of follicular thyroid carcinomas (FTCs) and in 17% (six of 36) of follicular thyroid adenomas, but in none of the 10 normal tissues, 28 nodular hyperplasias, 38 papillary thyroid carcinomas (PTCs) and 11 poorly differentiated thyroid carcinomas (PDTCs).     ///    "By real-time RT-PCR, we observed that tumours negative for the PAX8-PPARgamma rearrangement expressed lower levels of PPARgamma mRNA than the NT.
