ANXA1 and nasopharyngeal carcinoma: Because ANXA1 expression was significantly increased in the NPCs with metastasis relative to NPCs without metastasis (Fig. 1a, Supplementary Table S1), and ANXA1 expression was positively correlated with lymphonode and distant metastasis (Supplementary Table S2), we tested the effects of ANXA1 on NPC cell migration and invasion in vitro.
