TP53 and neoplasm: The inspection of substantially deregulated miRNAs overall confirmed prior studies on miRNA deregulation in ATC [14,37,38], e.g., the downregulation of the rather tumor-suppressive let-7 miRNA family, the TP53-driven miR-34c, and the pro-epithelial miRNAs of the miR-200 and miR-30 families [14].
