Abstract

Gene therapy using human sodium iodide symporter (hNIS) and radioiodine has been considered promising in a variety of gene therapy trials. However, the optimal timing of radioiodine application following hNIS gene transfer remains unknown. The present study aimed to investigate the serial expression of hNIS following adenovirus-mediated hNIS gene transfer into anaplastic thyroid carcinoma (ARO) to determine the optimal timing of radioiodine application. Recombinant adenovirus encoding the hNIS gene (rAd-hNIS) was generated using a homologous recombination reaction. The iodine uptake of rAd-hNIS‑transfected ARO cells gradually increased until 120 min post‑125I application but the fold increase, reflecting the relative uptake of rAd-hNIS‑transfected compared to non‑transfected ARO cells, reached plateau at 60 min post‑125I application. For the in vivo analysis, rAd-hNIS was injected intratumorally into ARO cell xenografts in the thighs of nude mice (n=12). Two, 3, 4 and 6 days after rAd-hNIS injection, γ‑scintigraphic images were obtained 60 min following injection of 5.5 MBq of 131I intraperitoneally. Treated/non-treated (T/NT) xenograft count ratios were the highest at day 2 post‑rAd-hNIS injection (2.85±0.61), and gradually decreased thereafter (2.54±0.65, 2.31±0.42 and 2.18±0.90 at days 3, 4 and 6 post‑rAd-hNIS injection, respectively). Real‑time polymerase chain reaction (RT-PCR) and immunohistochemical staining demonstrated that hNIS expression was the highest at day 2 following rAd-hNIS injection. In conclusion, the optimal timing for radioiodine administration is day 2 after adenovirus-mediated hNIS gene transfer into anaplastic thyroid carcinoma.
