A hidden warning sign discovered in the gut may increase cancer risk
As we get older, chemical marks on our DNA slowly shift. Now, a study reveals this 'drift' in gut stem cells is fueled by ...
DNA methylation in bacteria, primarily involving the addition of methyl groups to adenine or cytosine residues, constitutes a pivotal epigenetic mechanism that modulates gene expression without ...
"We find that epigenetic clocks based on the entropy of methylation states predict chronological age with similar accuracy as common approaches that are based on methylation levels of individual ...
