Compared with the NC tumours, the protein level of CD11b and CD14 greatly increased (Figure 5D) in ZEB1 knock‐down tumours, while the expression of cyclin D1, cyclin A2, p‐Rb and CDK4 was markedly decreased (Figure 5C) in ZEB1 knock‐down tumours. The gene discussed is ITGAM; the disease is neoplasm.
