5hmC Stands Apart from 5mC Through Single-Cell Multi-omic MethodsOctober 23, 2023Sometimes, you really want to stand out from the crowd. For years, 5-hydroxymethylcytosine (5hmC) has lurked in the shadows, often lumped together with 5-methylcytosine (5mC). However, these modifications have different effects—5mC generally turns down expression and 5hmC ramps it up. Sure, several methods can tease apart 5mC and 5hmC, but they require a lot of sample […]
Let It Rain: Droplets Generate Single-Nuclei Multiomes of Either Histone or RNA ModificationsSeptember 25, 2023A downpour of single-cell and single-molecule multiomics methods are prompting us to exclaim, “Let it rain!” We recently told you about a couple of single-molecule epigenetic mapping methods involving chromatin. And now, two new papers show how using a droplet-based microfluidic platform can provide multiomic information about single-cell transcriptomes along with histone modifications or RNA […]
Just Add HiDRO to Figure Out How Genomes Fold in Single CellsSeptember 14, 2023Water hydrates and is essential for life—for plants, humans, and even fish. So, it’s fitting that a new technique called HiDRO takes high-throughput FISH to the next level to identify factors that help genomes fold in 3D at high throughput in single cells. Cohesin helps DNA form loops, which can then form topologically associated domains (TADs). […]
Detecting Global Levels of 5mC and 5hmC at the Same Time—With ColorAugust 23, 2023Color is exciting and fun—just look at Andy Warhol’s striking silkscreen paintings of Marilyn Monroe. Now, a new method uses bright red and green fluorescence to detect global levels of both methylated and hydroxymethylated cytosine (5mCs and 5hmCs) modifications of genomic DNA in the same straightforward assay, which could lead to easy and inexpensive clinical […]
DM-Seq: A DM You’ll Want to Slide Into for Direct Methylation Sequencing of CytosinesJuly 31, 2023When someone slides into your DMs, it could mean that they are interested in you. Now, there’s a whole new meaning of “DM” for epigeneticists. Direct Methylation Sequencing (DM-seq) nondestructively maps 5mCs directly at single-base resolution with enzymes, and only needs nanograms of sample. There are already lots of ways to get at 5mC, including: Kohli’s […]
HiRES Lets You See Chromatin Structure and Transcription Clearly—At the Same TimeJuly 10, 2023To see clearly, sometimes you just need a good pair of glasses or contacts. Now, Dong Xing’s lab (Peking University) has combined single cell Hi-C and RNA-seq to get a “Hi-RES” picture of chromatin and gene expression from the same cells simultaneously. Sure, separate Hi-C and RNA-seq data from different cells have been combined before, but […]
Single-cell Epitranscriptomic Mapping of m6A from Small Samples with picoMeRIP-seqJuly 2, 2023Most successful epitranscriptomics studies rely on large amounts of input sample; however, huge findings may also reside in the smallest of specimens, such as zygotes or embryos. Now, a study provides exciting in vivo insight into these microcosms by describing the development of an epitranscriptomic mapping technique for single-cells and rare cell types. While traditional […]
BIND&MODIFY and NOMe-HiC Go the Distance with Single-Molecule, Long-Range Epigenetic MapsMay 4, 2023Staying in your own neighborhood can be nice, but sometimes you need to go on a trip and see different scenery. Chromatin is a lot like that—things can look very different along a DNA strand that bends and folds. That’s why two separate teams have come up with multi-omics methods that go the whole distance […]
Online Learning: Rinnformatics – Genome Informatics Classes for EveryoneApril 14, 2023If you’ve ever wanted to develop informatics skills to analyze sequencing data, but weren’t sure where to start, then we have the place for you! We found this fantastic resource built by Dr. John Rinn and his lab at the University of Colorado – Boulder. It’s a free, online series of courses that give you […]
Building Layers of Epigenome and Transcriptome Spatial Information in Single CellsMarch 27, 2023Layers make things a lot more interesting—a cake with chocolate, vanilla and strawberry layers is much more decadent than a single-tier vanilla one. And now the labs of Rong Fan (Yale University), Gonçalo Castelo-Branco (Karolinska Institute), and Yanxlang Deng (now at University of Pennsylvania) have put the icing on the cake with a new paper […]
