Figure 1. RT-PCR analysis of human sodium/iodide symporter (hNIS) and enhanced firefly luciferase (effluc) gene expression in MDA-231, MDA-231/NF cells and human thyroid tissue.

RT-PCR revealed hNIS mRNA expression in MDA-231/NF cells and human thyroid tissue, and effluc mRNA expression in MDA-231/NF cells. RT-PCR fragments have lengths of 583 bp and 316 bp for hNIS and effluc in MDA-231/NF cells; however, these bands do not appear in MDA-231 cells.
