Bisulfite treatment and sequencing analysis identifies methylation of BRD7 promoter. (A) Representative sequencing graphs of BRD7 promoter region in 5–8F cells treated with or without 5-Aza-CdR. Modified and unmodified cytosines are indicated by arrows. (B) Schematic depiction of methylated cytosine in BRD7 promoter region. The Cytosine under the "*" in the dinucleotide CpG indicates methylated cytosines.
