A reduction in C666-1 migration was also observed when incubated with conditioned media from co-culture of PLA2G7-silenced THP-1 cells with C666-1 as compared to conditioned media from control-transfected THP-1 cells co-cultured with C666-1, which confirms our findings that PLA2G7 plays an important role in regulating cell migration in NPC (Figure 7A and 7B). This evidence concerns the gene PLA2G7 and nasopharyngeal carcinoma.
