With a stable alternation of gene expression in cells during cell proliferation and differentiation process, DNA methylation plays a crucial role in the development of most types of cancer, neurodegenerative diseases and neurological diseases. Therefore, to characterize methylation of bases is critical to understand regulation of genes at epigenetic level. Sequencing of bisulfite-converted DNA provides a useful whole epigenome analysis tool for researchers to focus on specific tissues or dynamic developmental processes.
