The CCK8 assays showed that the Lv‐LUCAT1‐HepG2 cells, as well as Lv‐LUCAT1‐Huh7 cells, have increased proliferation ability compared to the control groups, whereas that of the sh‐LUCAT1‐MHCC97H cells and sh‐LUCAT1‐Hep3B cells were suppressed, indicating that LUCAT1 promotes HCC cell growth (Figure 2A). This evidence concerns the gene LUCAT1 and hepatocellular carcinoma.
