Environmentally Reprogrammed Sperm Epigenetically Transmit Behavior Across Generations

July 11, 2017

Life’s full of experiences that often seem like a coin toss. Should you go the gym or feast on some sushi? While the epigenetic mechanisms behind the outcomes of these two events may seem quite different at first, when considering the epigenetics of sperm, it turns out they’re two-sides of the same coin. Intergenerational Effect […]

“Drop” Everything for the New Liquid Model of Heterochromatin Domain Formation!

June 30, 2017

The field of epigenetics tends to be very “fluid” with new studies and paradigm shifts seemingly the norm! Now two new studies in Nature have described a new liquid model for the formation and function of silent chromatin domains known as heterochromatin. The predominant view of heterochromatin formation and function tells us that repressive epigenetic […]

Down is the New Up: Single Base-Pair Methylome Maps of Cancer

June 29, 2017

Navigating the highly variable features behind the epigenomic basis of cancer is no easy task: What’s up is down, what’s down is up! Thankfully, to aid our quest, the lab of Manel Esteller at the Bellvitge Biomedical Research Institute (IDIBELL) in Spain has brought forth a map as massive as the DNA methylation changes behind […]

Epromoters: Two Great Regulatory Functions for the Price of One!

June 19, 2017

Not many people can resist the allure of the ubiquitous neon signs promising fantastic two-for-the-price-of-one offers that promise to double the value of their hard-earned cash. Interestingly, these bargain offers also seem to be a feature in the human genome as a subset of promoters provide extra value by also acting as enhancers for other […]

HDACking Histone Acetylation With dCas9-HDAC3

June 12, 2017

Hacking the epigenome is no easy task. Each deactivated Cas9 (dCas9) system boasts its own nuances that must be teased apart before we can crack the histone code with its suite of effector domains. When it comes to histone acetylation, we’ve seen the histone acetyltransferase construct dCas9-p300, which writes H3K27ac to activate gene expression. However, […]

Tea Beats Coffee as a DNA Methylation Caffeine Fix in Women

June 10, 2017

There’s no denying that caffeine fuels epigenetic discovery, but now a recent epigenome-wide association study (EWAS) offers up a different epigenetic perspective about your daily caffeine fix. This creative rush comes at you from a European collaboration led by Uppsala University (Sweden). The team brewed up the first epigenome-wide association study (EWAS) of coffee and […]

The PARTICLE Accelerator of DNA and Histone Methylation Coordination

June 8, 2017

Finding the links between DNA methylation and histone modification is no easy chore. Long non-coding RNAs (lncRNAs) may be the answer; they are a huge part of the transcriptome, and many appear to be functional. There is growing evidence that lncRNAs act to “lnc” other epigenetic regulators together and coordinate their function. Adding to that […]

DNA Methylation is a Plus for Many Transcription Factors

June 6, 2017

When it comes to transcription factor binding, DNA methylation has a reputation as a trouble maker. When most people think of DNA methylation, they think of it blocking proteins from being able to bind. But does it deserve the bad rap? Though there are some examples of DNA methylation promoting binding of certain transcription factors […]

Drive the LINE: H4K20me3 Beats DNA Methylation at LINE-1 Chimeric Transcripts in Colorectal Cancer

April 10, 2017

The drivers of gene expression maintain a fragile balance that tends to cross the LINE in cancer. LINE-1s are transposable elements full of both mystery and regulatory potential. Within their 5’ untranslated region (UTR) lies a bidirectional promoter (L1-5’UTR) that consists of a sense promoter (L1-SP), which transcribes the element, and an antisense promoter (L1-ASP), which […]

Rapid m6A RNA Methylation Soothes Your Molecular Sunburns

April 10, 2017

Now that has spring has sprung, many of us are quickly remembering not only how much we missed the sunshine, but also that we forgot to stock up on aloe vera to soothe that fresh sunburn. Attesting to the utility of a good spot treatment, the lab of Yang Shi at Harvard Medical School reveals […]
