In order to analyse the effect of knockout or overexpression on the proliferation of gastric cancer cells, we showed that the overexpression of LINC01303 significantly increased the cell proliferation of GC cells by CCK8 and colony formation experiments, while the down‐regulation of LINC01303 significantly inhibited the proliferation of GC cells (Figure 2B,C). Here, LINC01303 is linked to gastric cancer.
