LncRNAs reportedly affect the expression of miRNA by acting as a competitive endogenous RNA (ceRNA), thereby influencing tumor progression.25 To identify the NEAT1 target miRNAs in RB cells, we used a target prediction tool Starbase 2.0, and selected miR‐124 as a probable target (Figure 4A) based on its role in regulating tumor progression.26 To confirm this prediction, we carried out luciferase assay and revealed that a significant reduction in the WT‐NEAT1 luciferase activity but not that of MT‐NEAT1 (Figure 4B; P < 0.05) as a result of miR‐124 overexpression. This evidence concerns the gene NEAT1 and neoplasm.
