Popis: Epigenetics: choose your DNA methylation probing tool wisely! Researchers who study human epigenetics need to carefully consider the platform used to measure genome-wide patterns of DNA methylation. A team led by Karin Michels and Andrea Baccarelli from Harvard University in Boston, Massachusetts, USA, empirically examined the strengths and weaknesses of two methylation profiling tools: Illumina’s Infinium BeadChip, which uses a microarray system to interrogate hundreds of thousands of methylation sites across the genome at single-nucleotide resolution; and a high-throughput sequencing-based approach known as rapid multiplexed reduced representation bisulfite sequencing, or rmRRBS. The former did a better job at reading methylation in protein-coding and mitochondrial-related genes, while the latter required less input DNA and covered more methylation sites across the genome. The authors conclude that a scientist’s platform preference should depend on the nature of his or her investigation.
