Whole genome bisulfite sequencing(WGBS)


Whole Genome Bisulfite Sequencing (WGBS) stands as the gold-standard methodology for in-depth exploration of DNA methylation, specifically the fifth position in cytosine (5-mC), a pivotal regulator of gene expression and cellular activity. The principle underlying WGBS involves bisulfite treatment, inducing the conversion of unmethylated cytosines to uracil (C to U), while leaving methylated cytosines unchanged. This technique offers single-base resolution, allowing researchers to comprehensively investigate the methylome and uncover abnormal methylation patterns associated with various conditions, notably cancer. By employing WGBS, scientists can gain unparalleled insights into genome-wide methylation landscapes, providing a nuanced understanding of the epigenetic mechanisms that underlie diverse biological processes and diseases.
