RET proto-oncogene is activated in the development of PTC via RET/PTC rearrangements. Single nucleotide polymorphisms (SNPs) of the gene are associated with PTC in some studies. We investigated possible association of SNPs with RET/PTC in Czech patients. We analyzed 234 patients with PTC (101 fresh frozen thyroid samples, 133 paraffin-embedded formalin-fixed samples) and 172 controls. RNA from frozen samples was reversely transcribed to cDNA. RET/PTC</i...

BRAF point mutations are found in 29-69% of papillary thyroid carcinoma (PTC). BRAF is a serine-threonine kinase involved in the phoshorylation of MAPK signaling pathway. The mutation is located in the exon 15 of BRAF, resulting in the substitution of valine to glutamate at codon 600 (V600E). Mutation generates unregulated B-Raf activity that leads to increased cellular proliferation. The aim of this study was to determine the frequency of BRAF mutation in the Czech population...
