MKI67 and colorectal carcinoma: In the MC38 intra‐splenic injection‐based liver metastatic model, acriflavine treatment markedly inhibited TROP2‐driven CRC liver metastatic colonisation, as evidenced by fewer liver metastasis nodules (Figures 6D and F and S7E), reduced liver weight (Figure 6E), and lower MKi67 expression levels (Figure 6D).
