Little evidence for mitochondrial DNA methylation

gettingwell4 2-3 stars Required further work, Epigenetics

This 2018 Japanese rodent study used three different techniques to detect mitochondrial DNA methylation: “Whilst 5-methylcytosine (5mC) is a major epigenetic mark in the nuclear DNA in mammals, whether or not mitochondrial DNA (mtDNA) receives 5mC modification remains controversial. We used bisulfite sequencing, McrBC digestion analyses and liquid chromatography mass spectrometry, which are distinctly differing … Continue reading Little evidence for mitochondrial DNA methylation
