The succinate dehydrogenase flavoprotein subunit gene (SDHA) was also significantly up-regulated in GO (P < 0.05), 1.4-fold, while genes encoding the thyroid antigens thyroglobulin, thyroid peroxidase and TSHR were not differentially expressed. qPCR verified up-regulation of CASQ2 and down-regulation BMP7, CD80, IGFBP5, and MYD88 genes in GO.
