Expression of RASSF1A, DIRAS3, and AKAP9 genes was also analysed using data obtained from the GEO database, including 227 pathologically changed tissues (35 FA, 44 FTC and 148 PTC) and 80 control non-cancerous tissues (including 44 samples from PTC and non-tumour control obtained from the same patients). This evidence concerns the gene AKAP9 and thyroid cancer, nonmedullary, 2.
