| Popis: | Aims: The BRAFV600E oncogene, reported in 40%–60% of papillary thyroid cancer (PTC), has an important role in the pathogenesis of PTC. It is associated with the loss of thyroid iodide-metabolizing genes, such as sodium/iodide symporter (NIS), and therefore with radioiodine refractoriness. Inhibition of mitogen-activated protein kinase (MAPK) pathway, constitutively activated by BRAFV600E, is not always efficient in resistant tumors suggesting that other compensatory mechanisms contribute to a BRAFV600E adaptive resistance. Recent studies pointed to a key role of transforming growth factor β (TGF-β) in BRAFV600E-induced effects. The reactive oxygen species (ROS)-generating NADPH oxidase NOX4, which is increased in PTC, has been identified as a new key effector of TGF-β in cancer, suggestive of a potential role in BRAFV600E-induced thyroid tumors. Results: Here, using two human BRAFV600E-mutated thyroid cell lines and a rat thyroid cell line expressing BRAFV600E in a conditional manner, we show tha... |
