MKI67 and neoplasm: We further examined the lung metastasis and subcutaneous tumorigenicity of B16‐F10 LCC in mice and confirmed a significant reduction in lung metastasis and tumor burden (Figure 1d,g), correlated with decreased proliferation (Ki‐67) rather than increased apoptosis (cleaved caspase‐3) (Figure 1e,f) and decreased tumor volume and weight (Figure 1h,i).
