XIST and thyroid gland carcinoma: Minna et al. reported a series of 18 miRNAs remarkably dysregulated (|fold-change| ≥ 1.5; FDR < 0.05) in thyroid cancer tissues compared to non-tumor thyroid tissues [28]; of the reported miRNAs, miR-34a inhibited XIST expression in thyroid cancer cells the most significantly in the present study.
