Figure 4From: Verification of genes differentially expressed in neuroblastoma tumours: a study of potential tumour suppressor genes BSP sequencing of the POU4F2 promoter. Cell-line SK-N-BE shows methylation of CpG sites in the POU4F2 promoter. Cytosines (blue peaks) marked with arrows, are modified into thymidines (red peaks) if not methylated. Cell-line SK-N-BE is compared to unmethylated primary tumour 9R9.Back to article page
