HOXD3 and neoplasm: Furthermore, the expression of HOXD3 and ITGA2 in LV‐shHOXD3 tumours was lower than that in control tumours (Figure 9F), and the expression of HOXD3 and ITGA2 was notably decreased in the HOXD3‐downexpressing treated tumours as compared with that in the control treated tumours at protein levels (Figure 9G).
