Notably, several cancer-related genes displayed a correlation between RNA expression and DNA methylation status, including MTOR, NOTCH1, and MAGI1. Furthermore, TSHR and SLC26A7, encoding the thyroid-stimulating hormone receptor and an iodine receptor highly expressed in normal thyroid, respectively, displayed low expression as well as aberrant gene body DNA methylation. Here, SLC26A7 is linked to cancer.
