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 […]
Updated cfDNA Nucleosomics Technology Upgrades our Epigenetic ClocksMarch 4, 2024A new style, novel functionalities, and a better overall product; we always want our smartwatches to employ the latest technology, and why not?! Now, a well-timed update involving cell-free DNA (cfDNA) nucleosomics-based technology provides for a significantly upgraded epigenetic clock, which may boost aging-based research. A punctual team led by Vladimir B. Teif (University of […]
Single-Molecule Methylation Profiles of Cell-Free Cancer DNA—Without Playing GamesJune 14, 2023Sometimes, you have to jump through a lot of hoops to get what you want. Hanlee Ji’s lab (Stanford) must be tired of playing those games because they’ve developed a direct single-molecule methylation nanopore sequencing approach for cell-free DNA (cfDNA) that doesn’t involve bisulfite conversion or even PCR. And yet it works on nanogram or […]
eBook: Epigenetics of Cancer & Disease RiskMay 3, 2023The application of epigenetic approaches to disease research is moving quickly and hundreds of new papers are published every year, from virology to neurobiology and cancer. In this eBook, we present short summaries of interesting discoveries that caught our attention in each of these areas. Table of Contents Chapter 1: Epigenetics in Disease Risk Taking […]
Placental Proxies: A Shared DNA Methylation Profile Between cffDNA and BrainSeptember 27, 2022When you’re looking to access the latest and greatest publications, your VPN is the proxy you need. But now, there’s a new proxy in town to help with your quest for neurodevelopmental epigenetic information: Placenta and the cell free fetal DNA (cffDNA) that originates from it. A dynamic duo of papers from the lab of Janine LaSalle (UC Davis […]
No Cells? No Problem! How Cell-Free DNA Methylation Profiles May Guide Cancer ManagementAugust 20, 2022When set the monumental task of studying how the epigenetic mechanisms underlying tumorigenesis, isolating a cell sample usually represents your first analytical port of call; however, research now suggests that liquid biopsies of a patient’s blood may provide a wealth of information from cell-free DNA. Furthermore, widening this approach to DNA methylation analysis may also […]
Multimodal Nanopore Profiling of Circulating Tumor DNAAugust 1, 2022The Oxford Nanopore (ONT) sequencing platform may have more modalities than a Swiss army knife. In a multimodal masterpiece of a new study, researchers now demonstrate how DNA methylation, copy number alterations, nucleosome footprinting, and fragmentation profiles derived from liquid biopsies of cancer patients can deconvolute cellular composition and identify cancer-specific methylation changes from circulating […]
EPIC Technique Infers Gene Expression from Cell-free DNA FragmentationMay 9, 2022It’s time to put down that well-thumbed copy of Homer’s Odyssey, as there is a new epic in town. Now, the “epigenetic expression inference from cell-free (cf)DNA-sequencing” (EPIC-seq) technique heroically enables gene expression analysis using a process known as “fragmentomics.” Circulating cfDNA comes as nucleosome-associated fragments that reflect the chromatin configuration in the cell of […]
Selfies from Beyond the Grave: CelFiE Deconvolutes Cell-free DNA Methylation MessagesJuly 27, 2021Although receiving a selfie from beyond the grave might sound disturbing, posthumous snapshots from dying cells in the form of the cell-free DNA (cfDNA) they release can help prevent us from entering an early grave. Giving Snapchat a run for its money is a new program called CelFiE (CELl Free DNA Estimation via expectation-maximization), which […]
