MYH9 and nasopharyngeal carcinoma: In addition, we found that overexpression of MYH9 obviously decreased the epithelial marker E-cadherin expression and remarkably increased the mesenchymal markers Vimentin, Slug, and Snail expression, while knockdown of MYH9 increased E-cadherin expression and decreased Vimentin, Slug, and Snail expression in NPC cells (Supplementary Fig. S5).
