RMRP and lung adenocarcinoma: Analogous to RPPH1, RMRP is also implicated as a molecular sponge for specific miRNAs that otherwise target genes associated with growth, including miR-206, in which case RMRP overexpression neutralizes miR-206 levels and activities in lung adenocarcinoma (Meng et al., 2016), neuroblastoma (Pan et al., 2019), bladder cancer (Cao et al., 2019), and hepatocellular carcinoma contexts (Hongfeng et al., 2020).
