Keeping up With Epigenetic Clocks: PRC2-AgeIndex Measures Gains of DNA Methylation Across the GenomeAugust 6, 2024While it may seem like it’s harder to keep up with epigenetic clocks than with the Kardashians, this is one you’re not going to want to miss. Many epigenetic clocks people use to assess aging are built on the DNA methylation status of a few CpGs, and it’s unclear how these sites are related to […]
CoRSIVs in Cows? Targeting a DNA Methylation Bullseye May Improve Livestock Farming!August 5, 2024Finding informative epigenetic targets in the genome is no easy task; however, cleverly composed studies previously reported on the discovery of correlated regions of systemic interindividual variation (or CoRSIVs) in humans – DNA methylation patterns that vary between individuals but remain consistent across tissues. Now, this talented team sets its sights on understanding this level […]
A CHARMing Epigenetic Editor Enchants Endogenous DNA Methylation Machinery to Pause Prion DiseaseJuly 8, 2024While George Clooney or Cate Blanchett exude a degree of charm, a captivating new epigenetic advance may outdo them both! A new study now describes a compact epigenetic editor known as “CHARM” that engages the cell’s own DNA methylation machinery to stop a fatal neurodegenerative disease in its tracks. A charismatic crew guided by Sonia […]
cfDNA Methylation Analysis Captures the Double Trouble of Inflammaging!July 1, 2024Analyzing cell-free (cf)DNA methylation from liquid biopsies represents a non-invasive approach to profile various diseases, but what if it could help us understand the devious duo of inflammaging – aging and inflammation? A talented team has dealt with this “double trouble” by applying enzymatic methyl-seq (EM-seq) to evaluate cfDNA methylation patterns. Researchers headed by Jian-Ping […]
DNA Methylation Differences in Imprinting Control Regions Contribute to Ethnic Disparities in Alzheimer’s Disease RiskMay 28, 2024Non-Hispanic Black (NHB) patients have a two-fold higher risk of developing Alzheimer’s disease than non-Hispanic White (NHW) patients for unknown reasons; now, a fascinating epigenetics study reveals the involvement of DNA methylation at imprinting control regions (ICRs). Researchers headed by Randy L. Jirtle and Cathrine Hoyo (North Carolina State University) explored ethnic variation in disease […]
