The results of the profiling (Figure 3A and Figure 3B) showed that while most of all the miRNA species examined showed downregulation in the Dicer-Pten DKO tumor lines, there were significantly elevated levels of miR-720 and miR-1937a, b, and c in the DKO tumor lines, which according to miRBase database (http://www.mirbase.org/index.shtml), belonged to tRNA fragments. Here, DICER1 is linked to neoplasm.
