The results showed that HSPA8 knockdown suppressed the expression of mesenchymal markers (ZEB1, Vimentin, and Slug), upregulated the epithelial marker (E‐cadherin and Claudin‐1) and consistently decreased migratory and invasive ability in CRC cells, while overexpression of HSPA8 resulted in the opposite phenotype (Figure 2C–L and Figure S4B–H, Supporting Information). Here, CLDN7 is linked to colorectal carcinoma.
