DDIT4 and cancer: Posttranscriptional gene regulation by lncRNAs is always mediated by associating with RNA‐binding proteins (RBPs), which are known to modulate the expression, stability, maturation, and transport of target mRNAs.[27] For example, lncRNA HMS functions as a HOXC10 mRNA stabilizing factor by associating with the HuR to stabilize HOXC10 mRNA, which has an essential role in the proliferation of cancer cells.[44] In our study, we found that DDIT4‐AS1 could directly bind to DDIT4 mRNA.
