(2017) Type 1 iodothyronine deiodinase (DIO1) contributes to deiodination of 3,5,3',5'-tetraiodo-L- Restoration of type 1 iodothyronine deiodinase thyronine (thyroxine, T4) yielding of 3,5,3'-triiodothyronine (T3), a powerful regulator of cell expression in renal cancer cells downregulates differentiation, proliferation, and metabolism. Our previous work showed that loss of DIO1 oncoproteins and affects key metabolic pathways as well as anti-oxidative system. PLoS ONE 12(12): enhances proliferation and migration of renal cancer cells. However, the global effects of e0190179. https://doi.org/10.1371/journal. DIO1 expression in various tissues affected by cancer remain unknown.
