RET/PTC oncogene activation occurs in about 20% of human thyroid papillary carcinomas. However, it is not known yet whether it is an early or late event in the process of thyroid carcinogenesis. Here we demonstrate, by using a combined immunohistochemical and reverse transcriptase-polymerase chain reaction based approach, that RET/PTC activation is present in 11 out of 26 occult thyroid papillary carcinomas analysed. Therefore, we conclude that it represents an early event in the process of thyroid cell transformation.

Abstract
RET/PTC oncogene activation occurs in about 20% of human thyroid papillary carcinomas. However, it is not known yet whether it is an early or late event in the process of thyroid carcinogenesis. Here we demonstrate, by using a combined immunohistochemical and reverse transcriptase-polymerase chain reaction based approach, that RET/PTC activation is present in 11 out of 26 occult thyroid papillary carcinomas analysed. Therefore, we conclude that it represents an early event in the process of thyroid cell transformation.File in questo prodotto:
