Therefore, we aimed to investigate its role in thyroid cancer progression and its potential as a... AB - Global hypomethylation of Alu repeats was used as a surrogate marker for DNA global hypomethylation, and was assessed using the Quantification of Unmethylated Alu technique. Mutations in BRAF and RAS were determined by Sanger sequencing. AB - Ninety primary thyroid tumors were included [28 low-risk differentiated thyroid cancer (DTC), 13 pediatric DTC, 33 distant metastatic DTC, 7 poorly differentiated thyroid cancer (PDTC), and 9 anaplastic thyroid cancer (ATC)], as well as 24 distant... AB - Distant metastatic DTC, PDTC, and ATC were increasingly affected by global Alu hypomethylation, suggesting that this epigenetic entity may be involved in thyroid cancer progression and dedifferentiation.
