In the transplanted tumor tissue constructed with H524 cells, the expression levels of CD31, Ki67, and c‐caspase‐3 in the 80 mg/kg group were not significantly different from those in the control group (P > 0.05), while the expression levels of CD31 and Ki67 were significantly decreased, and the expression levels of c‐caspase‐3 were significantly increased in the 120 mg/kg group, which were statistically significant differences compared with the control group (P < 0.05) (Figure 5G‐L). The gene discussed is PECAM1; the disease is neoplasm.
