In order to verify the effect of RRP12 on the metastatic ability of HCC, through the scratch experiment on HCCLM3, the scratch spacing of the NC group was significantly reduced after 48 hours, whereas the scratch spacing of the RRP12 knockdown group did not change significantly, so we concluded that the cancer cell invasion and migration ability decreased (Figure 8C). Here, RRP12 is linked to hepatocellular carcinoma.
