Immunohistochemistry and Western blotting revealed that xenograft tumours in the KYSE150 + CAFmiR‐193a‐3p KD group exhibited increased levels of PTEN and E‐cadherin and decreased p‐Akt and Snail expression compared with the KYSE150 + CAFControl group (Figure 6D,F). This evidence concerns the gene SNAI1 and neoplasm.
