In addition to let-7, the miRNAs miR-26a, miR-181, miR-9, miR-30, miR-125, miR-212 and miR-27 have also been shown to directly bind the 3′UTR of LIN28A/LIN28B and repress translation of the protein, and as these miRNAs are frequently under-expressed in malignant tumors, higher levels of LIN28 expression are seen [31–34]. The gene discussed is LIN28A; the disease is cancer.
