DNA methylation, whether in cells or in a cell-free environment, is one of the most powerful and most studied epigenetic regulators of gene expression and genomic organization. This is true for nearly all organisms, leading to the emergence of numerous methods for mapping 5-mC and 5-hmC and other modification states. There are many approaches for […]

Non-linear Alterations in DNA Methylation Provides Evidence of Aging in Stages!
Certain concepts – the speed of light, the electron’s charge, or the need to change cell media at the weekend – represent common constants in life. Many add the constant decay associated with the aging process to this list; however, analysis of DNA methylation in the mouse intestine now reveals that the aging process may […]
DNA Methylation Analysis Shows How Cannabis Exposure Increases the Risk of Adverse Health Outcomes
Do not risk missing a new paper describing a recent trans-ancestry epigenome-wide association study (EWAS) highlighting the significant health risks of recreational cannabis! In a fascinating new study, researchers now reveal that cannabis exposure can impact DNA methylation levels at specific regions independent of cigarette smoking to increase the risk of adverse health outcomes. Risk-averse […]
An Evolutionary and Epigenetic Tour-de-force Links DNA Methylation and Mammalian Aging
Have you climbed Mount Everest? Recorded a critically acclaimed album?? Written the great American novel??? These life-affirming feats of body and mind pale into insignificance when compared to the evolutionary and epigenetic tour-de-force reported in two recent papers based on mammalian DNA methylation datasets of colossal size and importance. An expeditionary force led by Steve […]
DNA Methylation Alterations Highlight Drivers of Aggressive Metastatic Tumors
The identification and early detection of events driving the metastasis of primary tumors may help identify therapeutic targets and patients that respond to specific therapeutics. Now, an epigenetic study focused on the spread of colorectal cancer to the liver reports DNA methylation as the spark driving metastatic events. Roadworthy researchers led by Euan J. Rodger, […]
