ABSTRACT
Elevated expression of c-Myc is associated with a variety of human cancers including clear cell renal cell carcinoma (ccRCC). Increasing evidence suggests that long noncoding RNAs (lncRNAs) are an important class of molecules that regulate both tumor initiation and progression. Here, we report the lncRNA c-Myc-induced regulator of ELF2 (MIRE) as a transcriptional target of c-Myc. MIRE functions as an oncogenic molecule in ccRCC by increasing ELF2 expression. Mechanistically, MIRE promotes phase separation of the RNA binding protein hnRNPK and facilitates the binding of hnRNPK to ELF2 mRNA, thereby resulting in the stabilization of ELF2 mRNA. Interestingly, MIRE is also under transcriptional control by ELF2, establishing an ELF2-MIRE positive feedback loop. Together, these findings provide new insights into the mechanisms by which c-Myc promotes tumorigenesis. They also implicate MIRE as an important regulator of ccRCC carcinogenesis.
