TUSC3 and cancer: Some lncRNAs function as sponges and regulate levels and activities of miRNAs.12, 13 miRNAs were primary regulators of gene expression via targeting 3’‐UTR of target genes14 and regulated biological processes in numerous cancers.16 In the current study, we indicated that DGCR5 shared miR‐873‐5p response element with TUSC3; elevated miR‐873‐5p expression status and downregulated TUSC3 mRNA level was discovered in neoplastic tissues in comparison with non‐neoplastic tissues.
