Although radioiodine has been applied in thyroid diseases including carcinoma for over 70 years, it was only in 1996 that the basic molecular mechanism of iodine uptake was identified. Iodide is actively transported into the thyroid via a membrane glycoprotein known as sodium iodide symporter (NIS). NIS mediates radioiodine uptake into thyroid normal and cancer cells. The knowledge on NIS expression has provided scientific background to the empirical management of thyroid carcinoma. Based on recent studies of the NIS gene, this paper provides current clinical applications and future studies.
尽管放射性碘已应用于包括甲状腺癌在内的甲状腺疾病治疗70多年,但直到1996年才确定碘摄取的基本分子机制。碘离子通过一种称为钠碘同向转运体(NIS)的膜糖蛋白被主动转运到甲状腺中。NIS介导放射性碘摄取进入甲状腺正常细胞和癌细胞。关于NIS表达的知识为甲状腺癌的经验性治疗提供了科学依据。基于对NIS基因的最新研究,本文介绍了其当前的临床应用及未来研究方向。
