As shown in Figure 8, the apoptosis rates of HepG2shMus81 and Bel‐7402shMus81 cells were slightly increased from 7.13 to 18.63% and from 3.76 to 12.53% when comparing with HepG2shCtrl and Bel‐7402shCtrl cells, suggesting Mus81 knockdown itself could slightly improve the apoptosis rate of HCC cells. The gene discussed is MUS81; the disease is hepatocellular carcinoma.
