Figure 3From: Allelic variation in the canine Cox-2 promoter causes hypermethylation of the canine Cox-2 promoter in clinical cases of renal dysplasiaRepresentative electropherograms from the DNA sequencing of bisulfite- converted DNA. (A) DNA that has not been converted with bisulfite (normal sequence). The primer set for this experiment was primer set 1 from reference [11]. (B) Wild-type allele showing that the CpG island of the Cox-2 promoter is unmethylated. (C) Electropherogram showing dense methylation of multiple alleles throughout the CpG island of the cyclooxygenase-2 (Cox-2) gene. (D) Electropherogram from Case number 2 (Shiz tzu) showing complete hypermethylation of the Cox-2 CpG island.Back to article page
