DNA-PK INHIBITION AGGRAVATES DOWN-REGULATION OF NIS-MEDIATED IODIDE-TRANSPORT IN NORMAL CULTURED THYROCYTES SUBJECTED TO GENOTOXIC STRESS

Norden M. M., Carlsson T., Nilsson M. Biomedicine, Sahlgrenska Academy Gothenburg University, Gothenburg, Sweden Abstract Uptake and accumulation of iodide is the most prominent feature of the thyroid gland. The function is regulated by both positive and negative signals acting on the NIS promoter, TSH being the strongest enhancer. Recent in vitro findings indicate that Read More
