Previous studies have shown that LMP1 expression correlates with fibronectin expression in nasopharyngeal carcinoma [52], and that functionally, LMP1-mediated fibronectin deposition facilitates epithelial cell adhesion and migration in an activin A/TGFβ and β1 integrin-dependent manner [7]. This evidence concerns the gene FN1 and nasopharyngeal carcinoma.
