Several studies have identified a relationship between oncogene activation and dedifferentiation of PTC. Mutations of RAS, RET/PTC and BRAF modulate the expression of thyroid genes. An impaired NIS expression has been demonstrated in PTCs harboring the BRAFV600E mutation.Aim of this study was to analyze BRAF and RET/PTC1-3 alterations and their influence on the expression of thyroid differentiation genes. Seventy-one PTC samples were studied. Quantitative analysis o...

BRAFV600E is the most common mutation in papillary thyroid carcinoma (PTC). Anatomo-patology and clinical features of PTC with BRAFV600E are well described in literature.Aim of this study was to examine the prognostic significance of BRAFV600E in patients with PTC and a follow-up of 15-20 years.Genomic DNA was purified from 67 paraffin-embedded tumoral tissue. A PCR-SSCP analysis of exon 15 of BRAF ...
