Besides, EOC is known to progress via the epithelial‐mesenchymal transition (EMT), during which cells lose cell‐cell adhesion, and develop migratory and invasive characteristics.23 Transcription factors Snail1 and Slug are known to downregulate adhesion molecule E‐cadherin and promote EMT.24, 25 Thus, the examination of EMT‐related markers was performed by western blot analysis and the results showed that Snail, Slug, and Vimentin were decreased, while E‐cadherin was increased after knockdown of EGFR or ABHD11‐AS1, consistent with inhibition of cancer cell migration and invasion (Figure 2D). This evidence concerns the gene EGFR and cancer.
