Organization of miRNA survival related clusters miR-17-92 and miR-106-363. Panel (a) depicts the structure of the two polycistronic miRNA genes identified in our previous work . Panel (b) lists the miRNAs constituting the survival signature identified by Srinivasani et al. The protective miRNAs signature could be identified without any a priori knowledge on its role in patients' survival in . Adapted from  and .
