Figure 5. Correlation of EBV copy number, HOXA2 methylation status and MMP-9 concentration in plasma samples from NPC patients.

Figure 5

Plasma was collected from five NPC patients at different time intervals (1~3 months) after standard NPC treatments (including radiation and chemotherapy) were administered according to the CGMH guidelines (N=22). (A-D) Correlations were observed between the log EBV DNA copy number, HOXA2 methylation status and plasma MMP-9 concentration. Pearson's correlation coefficients (r) are indicated. (E) Plasma MMP-9 concentrations from 22 NPC samples and seven healthy donors were measured by ELISA. The results are shown as mean±SD (** p<0.01).
