CDH1 and neoplasm: Then, we assessed the expression of E‐cadherin and N‐cadherin in xenograft tumour tissue sections and found that the expression of E‐cadherin was lower in RKO‐NC and SW480‐R than that in RKO‐shR and SW480‐NC, while the expression of N‐cadherin was higher in RKO‐NC and SW480‐R than that in RKO‐shR and SW480‐NC (Figure 3B, 3C).
