The positive rate of proliferation index Ki67 (Figure 2J) and the number of lung metastatic nodules (Figure 2K) were significantly reduced after silencing MAFG‐AS1, while overexpression of MAFG‐AS1 exerted promoting effects on the tumor volume (Figure 2I), proliferative ability (Figure 2J), and lung metastatic capacities (Figure 2K). This evidence concerns the gene MKI67 and neoplasm.
