Two Barcodes, One DNA Fragment: Budget-Friendly Single-Cell Whole-Genome Bisulfite Sequencing

April 29, 2018

While single-cell whole-genome bisulfite sequencing is rapidly evolving, the associated price tag hasn’t been quite as dynamic. This lack of dynamism is primarily because current single-cell whole-genome bisulfite sequencing (scWGBS) methods are limited by the need to process each cell in individual reaction vessels and also low alignment rates. These limitations mean a high (financial) […]

TERRA lncRNA Tailors a Trimethylation Trio at Telomeres

April 27, 2018

A good tailor will make any scientist look presentable in an expensive suit or a glitzy dress (when we escape the confines of a lab coat) and now, the group of Maria A. Blasco (CNIO, Madrid, Spain) describes how long non-coding RNAs (lncRNAs) tailor our telomeric DNA with just enough trimethylated histones to suit any […]

Transposons and DNA Methylation Learn to Get Along

April 26, 2018

A lot of things just don’t mix well, dogs and cats, oil and water, and as most geneticists would agree, transposons and DNA methylation. DNA methylation is the mortal enemy of transposon activity; across the tree of life it has a conserved role silencing transposable elements from plants, to algae, to vertebrates. This suggests DNA […]

dmrseq Powers-Up Whole-Genome Bisulfite Sequencing Analysis

April 16, 2018

In our modern world, power is everything. Whether it be political, social, or even statistical, humankind always thirsts for more. While political and social power may be a little beyond our scope, a new bioinformatic package has come forth to power up your ability to detect differentially methylated regions (DMRs) from whole-genome bisulfite sequencing (WGBS) […]

Classification Conundrums: DNA Methylation and Central Nervous System Tumors

April 13, 2018

It’s human nature to categorize the world around us. From the earliest taxonomic classification defining us as Homo sapiens, we’ve grouped dogs by breed (pugs, bulldogs, retrievers), wines by grape (merlots, chardonnays, pinot noirs), and of course, cancers by origin (gliomas, melanomas, sarcomas). You can order a DNA test for your dog, or ask the […]

Don’t Blame Mom, Thank Her! Extra Maternal Care Creates a Stress Resilient Epigenomic Profile in the Developing Brain

April 10, 2018

Stress is something we are all too familiar with. When it comes down to a stressful situation, it seems that there are almost two types of people: those stricken by anxiety and depression, and those who keep on walking on as if nothing has happened. But what shapes such a distinction between people? One contributing […]

Hemimethylated CpGs: Paradox or Paradigm?!

March 28, 2018

Science is full of paradoxes, and while we humble epigeneticists have yet to come across a cat that is both alive and dead, we have discovered a mysterious states of DNA methylation! For instance, some CpG sites can be both methylated and unmethylated at the same time, depending on which strand it is located on. […]

Transgenerational Epigenetic Inheritance of a Trio of Epigenomic Changes Induced by DDT

March 27, 2018

DNA methylation has long been the shining star of transgenerational epigenetic inheritance work, with other mechanisms signing backup. But now, the solo act has now become a trio, with histone modifications and non-coding (ncRNA) stepping into the limelight. For an in utero exposure to be truly transgenerational, and not an intergenerational effect, it must impact […]

Embrace Your Age! Age-related H4K16ac Gains Protect Your Brain from Developing Alzheimer’s Disease

March 19, 2018

In our quest for the fountain of youth, we often find ourselves attracted to anything that will fight off the signs of aging. But now, the first genome-wide analysis of a specific histone modification in the brains of human patients affected by Alzheimer’s disease (AD) demonstrates that we should embrace the epigenetic changes that come […]

Cutting Through the Epigenetic Complexities Linking Aging and Tumorigenesis

March 16, 2018

Writing your first grant proposal? Optimizing that tricky Western blot? Programming an old PCR machine? Only a few things are more complex than our current understanding of the epigenetic links between aging and tumorigenesis, but this has not stopped a few valiant labs from doubling down and busting a few paradigms while they are at […]
