The results showed that less tumor volumes, weights, Ki‐67 positive cells as well as lung metastasis nodules were observed in ARAP1‐AS1‐depleted groups as compared with control groups (Figure 2E,F), likewise, the opposite trends were displayed in ARAP1‐AS1‐overexpressed groups (Figure 2E,F). This evidence concerns the gene ARAP1 and neoplasm.
