Targeted expression of the ret/PTC1 oncogene induces papillary thyroid carcinomas.

The ret/PTC oncogene, a rearranged form of the ret proto-oncogene, has been found to be restricted to human papillary thyroid carcinomas. This report shows that transgenic mice with thyroid-targeted expression of the ret/PTC1 oncogene developed thyroid carcinomas with considerable similarities to human papillary thyroid carcinomas, particularly in the nuclear cytologic features and the presence of local invasion. Our findings indicate that ret/PTC2 is not only a biomarker associated with papillary thyroid carcinomas, but is also the only proven specific genetic event leading to the development of papillary thyroid carcinoma.Journal ArticleResearch Support, Non-U.S. Gov'tResearch Support, U.S. Gov't, P.H.S.info:eu-repo/semantics/publishe
