Abstract
Increasing evidence showed that long non-coding RNAs (lncRNAs) play critical roles in tumor progression. FEZF1-AS1 is a cancer-associated lncRNA which upregulated and associated with poor prognosis in patients with cancer. However, the roles of FEZF1-AS1 in multiple myeloma (MM) remains unclear. In the present study, our data revealed that FEZF1-AS1 expression was increased both in MM samples and cell lines. Loss of functional assays indicated that FEZF1-AS1 suppression inhibited MM cells proliferation, arrested cell cycle in G0/G1 phase and induced cell apoptosis in vitro. Furthermore, our data indicated that FEZF1-AS1 functioned as a competing endogenous RNA in MM cells that regulated miR-610 expression, which suppressed Akt3. Those data showed that FEZF1-AS1 promoted MM cells proliferation through regulating miR-610/Akt3 axis, suggesting FEZF1-AS1 could be served as a potential target for cancer therapeutics in MM.
