    A cDNA encoding an NADPH oxidase flavoprotein was isolated from the rat thyroid gland. The predicted 1517-residue polypeptide was 82.5% identical to the human THOX2/DUOX2 and 74% similar to THOX1/DUOX1. Rat THOX2 lacks a stretch of 30 residues, corresponding to one exon in the human gene sequence. THOX2 mRNA was found to be expressed in cultured FRTL-5 cells. The level of THOX2 mRNA was increased by cAMP in these cells and it was decreased in the thyroids of rats treated with the antithyroid drug methimazole, unlike the TPO and NIS mRNAs. Since it was found in the intestine, duodenum, and colon, in addition to thyroid, we suggest that it be called LNOX, the new family of long homologs of NOX flavoproteins rather than THOX and/or DUOX.

    • Thyroid (Armour® Thyroid)

      Thyroid is a hormone produced by the body. When taken correctly, thyroid is used to treat the symptoms of hypothyroidism (a condition where the thyroid gland does not produce enough thyroid hormone). Symptoms of hypothyr...

    • Methimazole (Tapazole®)

      Methimazole is used to treat hyperthyroidism, a condition that occurs when the thyroid gland produces too much thyroid hormone. It is also taken before thyroid surgery or radioactive iodine therapy.
