Figure 4From: Epigenetic markers for early detection of nasopharyngeal carcinoma in a high risk populationScatter diagram of relative quantity of methylation of (A) CADM1 and (B) MAL gene. The Y axis is expressed in log scale. CADM1 (A) showed an insignificant variations between normal brushing and NPC brushing and between NPC brushing and NPC paraffin (one-way ANOVA using Tukey analysis p = 0.654 and 0.069 respectively). Thus Q-MSP confirmed the result of MSP. MAL (B) showed insignificant variations between normal brushing and NPC brushing (p = 0.070). Methylation level in NPC paraffin was comparable to NPC brushing (p = 0.069) but was significantly higher compared to normal brushing (p = 0.002) indicating that MAL methylation can be a promising marker for NPC detection. HR = high risk, NPC = nasopharyngeal carcinoma.Back to article page
