Figure 1. Methylation assay of the CBS gene and its quality control. (A) The abridged general view of five CpG sites on the CBS gene promoter. F: forward primer; R: reverse primer. The genomic positions and functional annotations of CBS were obtained from the UCSC genome browser according to human 2013 (GRCh37/hg19). (B) Methylation status of the CBS gene in patients with hypertension was analyzed by quantitative methylation-specific PCR.
