Figure 2B indicates that LINC00449 was markedly downregulated in these cells by si-LINC00449. Additionally, the OD value of si-LINC00449 at 450 nm decreased, implying a reduction in the HCC cells’ proliferation ability (Figure 2C and D). The plate cloning assay demonstrated that si-LINC00449 reduced the number of cell clones in Figure 2E. Figure 3A presents the number of migrating cells detected, indicating a weakened level of cell migration. Similarly, transfection of si-LINC00449 resulted in reduced invasiveness of HCC cells (Figure 3B). This evidence concerns the gene LINC01232 and hepatocellular carcinoma.
