To analyze the effects of lncPARP1 silence on HCC cell proliferation, we performed CCK-8 assay and found that knockdown of lncPARP1 remarkably inhibited proliferation of both Bel-7402 and PLC/PRF/5 cells, compared with that of control cells (Figure 2B). The gene discussed is LINC01703; the disease is hepatocellular carcinoma.
