Our review on paternal intergenerational epigenetic inheritance and the instructive sperm epigenome is now out!

We summarize how the paternal genome instructs the earliest stages of embryonic development and how environmental exposures can reshape this process.

A father’s legacy: the sperm epigenome, preimplantation development, and paternal environment
Paternal exposure to the environment can influence offspring phenotypes via a process known as intergenerational epigenetic inheritance. Such form of inheritance involves the sperm epigenome that i...

❓Can a father’s environmental exposures before conception influence their offspring?

We systematically tackled this - identifying effects of paternal age, environment and genetics on early embryos - as well as confounding influences

🚨 Preprint alert 🚨
Excited to share our work on "Ab-trapping," an antibody artifact causing misleading peripheral ("rim") staining in imaging & genomics (IF, CUT&Tag, CUT&RUN). Antibodies fail to penetrate structures, accumulating at the periphery. A 🧵👇

Ab-trapping - a peripheral staining artifact in antibody-based microscopy and genomics
Antibodies (Ab) are essential for detecting specific epitopes in microscopy and genomics, but can produce artifacts leading to erroneous interpretations. Here, we characterize a novel artifact, Ab-tra...

The DNA in our cells is not naked but instead is compacted by being wrapped around nucleosomes assembled from histone proteins. In our current view, this produces the chromatin architecture that leaves some regions open for transcription while others are more compacted & transcriptionally silent 1/n

We're so thrilled to finally share with you the published version of our CUT&Tag optimization and benchmarking paper "CUT&Tag recovers up to half of ENCODE ChIP-seq histone acetylation peaks" - out in @naturecomms.bsky.social today: www.nature.com/articles/s41...
CUT&Tag recovers up to half of ENCODE ChIP-seq histone acetylation peaks - Nature Communications
Cleavage Under Targets & Tagmentation is a rapidly expanding technique, but thorough evaluation and benchmarking against established ChIP-seq datasets are required. This study shows that CUT&T...

This is a reminder that there is still space in this starter pack if you want to join 🤩. Just send us a message!
Please join this starter pack for everyone working from chromatin replication to epigenetic inheritance and cell fate! Now still small, but we hope to gather everyone interested in joining. Please message us to be added, go.bsky.app/ALFFRUN
