We are pleased to announce a new preprint by @mlweilert.bsky.social: “Widespread low-affinity motifs enhance chromatin accessibility and regulatory potential in mESCs” (www.biorxiv.org/content/10.1...). See summary and longer recap below:

(TLDR; low-affinity motifs matter as pioneers!)
Widespread low-affinity motifs enhance chromatin accessibility and regulatory potential in mESCs
Low-affinity transcription factor (TF) motifs are an important element of the cis-regulatory code, yet they are notoriously difficult to map and mechanistically incompletely understood, limiting our a...

Finally, we propose a model in which chromatin is self-organising based on histone acetylation and nucleosome depletion. We hypothesise that active cis-regulatory elements may contact one another at or above a layer of acetylated nucleosomes.

Spread the word! There is a professor position opening at our University @upcite.bsky.social. There are several possible (great) labs to join, but if you are interested in DNA methylation and epigenetics in mammals, don't hesitate to contact me directly!

Do we need LLMs to predict epigenomes from DNA—or is biophysics enough? 🧬
IceQream (IQ) is a biophysics-based framework that predicts epigenomes with SOTA-level accuracy—and is fully explainable.

We lack clear guidelines for AI use by our students. My attempt:

Encouraged (when used responsibly):
✅Exploration, brainstorming and troubleshooting
✅Controlled software development and debugging

Discouraged (in most cases):
🚫Writing or "improving" academic texts
🚫Creating academic illustrations

Just received a notification that our university is renegotiating #openaccess agreements with the “big five” publishers (Springer, Elsevier, etc), and it is highly likely that we will lose some of these agreements. If we do, this will be a big problem since we do not have budgets to pay OA fees

Sequencing advice sought:
Anyone have any experience of Element AVITI sequencing for methylation profiling by WGBS or EM-sequencing?
Useful to know what other people's experience is as local facility have one and cheaper than Illumina for short read sequencing.
Please share 🙏

Now that I'm settled in at @umasschan.bsky.social, I'm hiring at all levels: grad students, post-docs, and software engineers/bioinformaticians!

The goal of my lab is to understand the regulatory role of every nucleotide in our genomes and how this changes across every cell in our bodies.

Interesting paper from Gernot Längst & Co. They calculated nucleosome repeat length in Plasmodium falciparum, the malaria-causing parasite, and showed that it follows a smooth continuous function of time (the numbers on the X axis below are hours post-invasion) www.biorxiv.org/content/10.1...

Many enhancers that drive tissue-specific gene expression are already connected to gene promoters in human pluripotent cells.

In a new preprint, we share some clues about when, how, and why this happens!
