The c-Myc oncoprotein plays a prominent role in cancer initiation, progression, and maintenance. Long noncoding RNAs (lncRNAs) are recently emerging as critical regulators of the c-Myc signaling pathway. Here, we report the lncRNA USP2-AS1 as a direct transcriptional target of c-Myc. Functionally, USP2-AS1 inhibits cellular senescence and acts as an oncogenic molecule by inducing E2F1 expression. Mechanistically, USP2-AS1 associates with the RNA-binding protein G3BP1 and facilitates the interaction of G3BP1 to E2F1 3′-untranslated region, thereby leading to the stabilization of E2F1 messenger RNA. Furthermore, USP2-AS1 is shown as a mediator of the oncogenic function of c-Myc via the regulation of E2F1. Together, these findings suggest that USP2-AS1 is a negative regulator of cellular senescence and also implicates USP2-AS1 as an important player in mediating c-Myc function.
