Methylation’s Moonlighting Mysteries: DNMT3L’s Divergent Roles in Down SyndromeApril 12, 2021By daylight, DNA methyltransferase 3L (DNMT3L) takes on the modest role of a catalytically inactive but stimulatory binding partner for its more popular methyltransferase siblings (DNMT3A and DNMT3B). But, when the sun goes down, DNMT3L gives new meaning to protein moonlighting. DNMT3L is located on chromosome 21, which has made it a prime candidate for the Down syndrome […]
From Single Molecules to Single Cells: NanoMethPhase and scMspJI-seq Upgrade DNA Methylation Mining MethodsApril 2, 2021Mining the DNA methylome can provide a treasure trove of biological insight, and two new whole-genome DNA methylation sequencing methods have come along to fuel a technological gold rush. NanoMethPhase and scMspJI-seq break new ground in phasing allele-specific methylation (ASM) and generating strand-specific single-cell methylomes. By applying these novel approaches, the talented teams dig deep into complex DNA […]
Cancer-associated Histone Mutations Modulate Nucleosome Remodeling to Get That Histone Body Moving!March 26, 2021While any new study mentioning histones generally gets our epigenetic tails wagging, a stunning study into how cancer-associated histone mutations influence nucleosome remodeling has also got our “globular” bodies moving! Although most researchers focus on mutations in the histone tail, most high-frequency cancer-associated mutations actually affect the main “bodies” of the histone proteins (known as […]
The Epigenetic Clock – From Deep Space to Deep LearningDecember 30, 2020As the year comes to its end, our epigenetic clocks keep on ticking, and hot new DNA methylation-based studies keep rolling in. Here, we gaze into two deeply interesting studies that take us on an epigenetic journey from deep space to deep learning by reporting how space travel can influence epigenetic aging and how neural […]
C.elegans Studies Worm into the Fundamentals of Transgenerational Epigenetic InheritanceSeptember 21, 2020While a “bird’s-eye view” of a topic can often provide colossal insight, the opposite perspective can sometimes be just as useful! Recently, two fascinating studies of transgenerational epigenetic inheritance have taken a “worm’s-eye view” of this research area to deepen our understanding of this complex mechanism in the model nematode worm C. elegans. C. elegans […]
Micro-C and Single-Cell Hi-C Provide Macro Chromosome Conformation InsightsApril 11, 2020Genome-wide chromosome conformation capture analyses, such as Hi-C, have provided us with snapshots of the large-scale spatial architecture of mammalian genomes, describing chromatin compartments, topologically associating domains (TADs), and CTCF– and cohesin-mediated chromatin loops in many cell types. However, the resolution of Hi-C-based protocols, limited by the size and uniformity of chromatin fragmentation, represents a […]
EpiGenie Guide: Chromatin ShearingMarch 6, 2020ChIP-Seq has transformed the field of epigenetics, providing unprecedented resolution and coverage for surveying protein- DNA interactions. Powerful, high-throughput sequencing is credited with most of the benefits, but there’s a lot more that goes into ChIP-Seq than sequencing. Chromatin shearing is one of the first critical steps in the ChIP-Seq workflow. Depending on your approach, […]
MeCP2 on the Brain: Repressing Transcription of Long Highly Methylated GenesDecember 17, 2019It seems that everyone has MeCP2 on the brain – as evidenced by its starring role in two new Molecular Cell papers – but it’s in your brain too! The MeCP2 protein is essential for neuronal function and consistent with this, loss-of-function mutations in MeCP2 cause the neurodevelopmental disorder Rett syndrome. Unfortunately, because MeCP2 acts […]
A Perfect Harmony: Orchestrating Joint Chromatin Conformation and Methylome Mapping in Single CellsOctober 7, 2019If a better understanding of gene regulation is music to your ears, then tune in for the latest developments in single-cell epigenomics. It is well established that both DNA methylation and higher-order chromatin structure play crucial roles in development, differentiation and disease, and there are readily available technologies for both (whole-genome bisulfite sequencing and chromatin […]
Webinar: The Epigenetics of the Exposome and Aging – Paul G. ShielsOctober 2, 2019Don’t miss this great webinar detailing some of the latest discoveries about the role of epigenetics in aging. Aging results in a gradual and progressive loss of physiological functions and physical abilities over time. Overcoming the growing burden of age-related issues is one of the greatest challenges facing modern society. These issues are leading to […]
