Whole genome bisulfite sequencing is a next-generation sequencing technology used to determine the DNA methylation status of single cytosines by treating the DNA with sodium bisulfite before high-throughput DNA sequencing. The DNA methylation status at various genes can reveal information regarding gene regulation and transcriptional activities. This technique was developed in 2009 along with reduced representation bisulfite sequencing after bisulfite sequencing became the gold standard for DNA methylation analysis.

dbo:abstract
  • Con il termine sequenziamento bisolfito dell'intero genoma, in lingua inglese Whole genome bisulfite sequencing (WGBS), si indica una tecnica di biologia molecolare che permette di determinare lo stato di metilazione di un intero genoma a livello di singole citosine. Tale tecnica si basa sul trattamento del DNA di interesse con sodio bisolfito, seguito da sequenziamento di prossima generazione (Next Generation Sequencing, NGS). In particolare, il sodio bisolfito è un composto chimico in grado di deaminare le citosine non metilate in uracili, i quali sono in seguito convertiti in timine. Al contrario, le citosine metilate non vengono convertite, risultando alla fine della reazione citosine. In seguito è possibile determinare l’esatta posizione genomica delle citosine metilate confrontando la sequenza del campione trattato con sodio bisolfito con quella dello stesso campione non trattato (o più spesso con la sequenza del genoma di riferimento disponibile per una data specie).

The DNA methylation status at various genes can reveal information regarding gene regulation and transcriptional activities. This technique was developed in 2009 along with reduced representation bisulfite sequencing after bisulfite sequencing became the gold standard for DNA methylation analysis. Whole genome bisulfite sequencing measures single-cytosine methylation levels genome-wide and directly estimates the ratio of molecules methylated rather than enrichment levels. Currently, this technique has recognized and tested approximately 95% of all cytosines in known genomes. With the improvement of library preparation methods and next-generation sequencing technology over the past decade, whole genome bisulfite sequencing has become an increasingly widespread and informative method for analyzing DNA methylation in epigenomic-wide studies.
