The redox gene expression patterns of Thyroid MSCs compared to PTC MSCs were similar to the expressions observed in thyroid epithelial Nthy and TPC1 cells, with the exceptions of SOD3 and NOX4. The NOX4 gene was undetectable in the epithelial Nthy and TPC1 cells, whereas Thyroid MSCs and PTC MSCs both had high NOX4 expression levels. This evidence concerns the gene NOX4 and thyroiditis.
