Furthermore, we knocked out OGG1 using CRISPR/Cas9 technology (Figure 2H,I) and the results were consistent with those obtained from OGG1‐knockdown cells, highlighting the criticality of OGG1 in mediating oxidative stress‐induced tumour migration and invasion (Figures 2J–L and S2F). The gene discussed is OGG1; the disease is neoplasm.
