From: Effect of cigarette smoke condensate on gene promoter methylation in human lung cells
Heatmap of the intensity of promoter methylation of the 24-genes panel in PSAE (human primary small airway epithelial) cells. Cells were cultured in the absence or presence of 0.3 or 1.0 μg/ml CSC for 3, 14 or 30 days. Methylation was assessed by the Methyl-Profiler DNA Methylation PCR System. Methylation analysis in the lung cancer lines, A549 and H1299, is also represented. Color code and intensity indicate level of methylation.
