Moreover, FGD4 mRNA was expressed at a higher level in NPC specimens than in controls (0.422±0.173 vs. 0.131±0.135; P = 0.0005; two-tailed Mann Whitney test); however, no correlation was observed between the levels of FGD4 and LMP1 mRNA (P = 1; Spearman test). This evidence concerns the gene PDLIM7 and nasopharyngeal carcinoma.
