Figure 6From: Gene promoter methylation assayed in exhaled breath, with differences in smokers and lung cancer patients Methylation density of DAPK promoter by tumor histology in lung cancer cases. The methylation density of DAPK promoter in EBC samples from adenocarcinoma, squamous cell carcinoma, non-small cell carcinoma and small cell carcinoma (n = number of subjects) was compared by ANOVA multiple group comparison. There was no significant difference in methylation density between adenocarcinoma, squamous cell carcinoma, non-small cell carcinoma and small cell carcinoma (p = 0.401)Back to article page
