WebIodide is accrued from the blood into thyroidal cells through the sodium/iodide symporter (NIS). It is attached to the tyrosyl residue of TG through the action of thyroid peroxidase (TPO) in the presence of hydrogen peroxide (H2 O 2). WebFeb 27, 2024 · Conclusions: The findings of this preclinical study showed that ALK fusion-induced downregulation of NIS, the prerequisite of RAI refractoriness, could be reversed in thyroid cells by either direct inhibition of ALK or its downstream signaling pathways.

Webremains unclear. To gain insight into the function of nominally thyroid-specific genes in skin, we analyzed the expression of thyroid-stimulating hormone–receptor (TSH-R), thyroglobulin (Tg), sodium iodide symporter (NIS), and thyroperoxidase (TPO) genes in normal human skin biopsies and cultured primary keratinocytes and dermal fibroblasts. WebOct 31, 2012 · NIS-mediated iodide uptake also forms the basis for the diagnostic nuclear imaging and radioiodine therapy for thyroid diseases. Radioiodine therapy following NIS gene transfer was shown to be efficient in nonthyroid, especially, liver cancer models.
