Extrathyroidal role of iodine / 中华内分泌代谢杂志

ABSTRACT

As an essential micronutrient in mammals, iodine is involved in the synthesis of thyroid hormone and plays an important role in human life. Iodine itself has the characteristics of chemical elements, such as antioxidant, anti-inflammatory, and other effects. It plays a role in some free radical-related chronic diseases. Iodine also has anti-proliferation and pro-apoptotic effects on some tumor cells to inhibit tumor development. At present, many studies about iodine focus on its role in thyroid gland and its hormone. A little attention has been paid to the extrathyroidal action of iodine. Here we reviewed the role of iodine in extrathyroidal tissues and organs with iodine uptake capacity and its effect on metabolism.
