The colony formation assay demonstrated that colonies were reduced remarkably in the si-LINC00152 group than in the si-NC group (P<0.05), indicating that LINC00152 silencing suppressed GC cells proliferation (Figure 2B), and CCK-8 assay detected cell viability in different time points also showed similar results (Figure 2C). This evidence concerns the gene CYTOR and gastric cancer.
