Then, we predicted the binding site of miR-383 to MCUR1 by microRNA target scanning algorithm software, and confirmed that miR-383 directly interacts with MCUR1 by dual-luciferase analysis (Fig. 3I).Database analysis suggested that MCUR1 levels were elevated in HCC tissues and higher levels of MCUR1 expression were associated with poor prognosis (Fig. S3E-F). Here, MCUR1 is linked to hepatocellular carcinoma.
