Figure 2. LDLRAD2 promotes in vitro migration and invasion of GC cells. Overexpression of LDLRAD2 in MGC-803 and MKN28 cell lines and silenced LDLRAD2 in BGC823 cell line (A). Overexpression of LDLRAD2 significantly enhanced morphological characteristics of EMT of MGC-803 cell line, while silence of LDLRAD2 significantly inhibited morphological characteristics of EMT of BGC823 cell line (B). Western blotting analysis showed that the expression levels of epithelial cell markers such as E-cadherin and γ-catenin were dramatically decreased, while mesenchymal cell markers such as N-cadherin and vimentin were significantly increased in LDLRAD2-overexpression cell lines (C). The expression levels of epithelial cell markers were increased, while mesenchymal cell markers were decreased in LDLRAD2-silenced cell line, (C). LDLRAD2-overexpression MGC-803 cell exhibited significantly enhanced invasive capability (D), while LDLRAD2-silenced BGC-823 cell had dramatically decreased invasive capability (E).
