“After incubation with Dex, iodide accumulation in NP-1 cells increased up to 1.5-fold, whereas NIS mRNA and protein expression levels were increased up to 1.7-fold.”
“In conclusion, in addition to an antiproliferative effect, treatment with Dex increases androgen-dependent NIS mRNA and protein expression as well as iodide accumulation, resulting in an increased cytotoxic effect of 131-I in prostate cancer cells stably expressing NIS under the control of the PSA-promoter.”
