New preprint from the lab! We dig into the regulatory roles of TEs in the mouse placenta, with some surprising findings. Led by the awesome @smamante.bsky.social. Particular kudos to him for navigating the many twists and turns of the project.
New preprint from our lab: ‘Retroviral insertions contributed to the divergence of human and chimpanzee brains’. Very proud of this piece which took almost a decade to finish.

#1 Centromeres are epigenetic loci defined by CENP-A, positioned in unmethylated DNA flanked by highly methylated regions. Our work, published in @natgenet.nature.com in collaboration with @naltemose.bsky.social investigates the role of DNAme at human centromeres www.nature.com/articles/s41...
New paper from our lab! We found that LINE-1 transposons contribute to early human brain development.

Very happy to share our protocols paper for CELLO-seq. This will make single cell long read RNA-seq more accessible and provides analysis guidelines. We hope this helps the #transposon #TEsky community and folks working on #singleCell isoform and allelic #gene expression. doi.org/10.1038/s415...
A must read!
We are looking for new colleagues to come join us in Galway as group leaders (Junior and Senior). The Centre for Chromosome Biology is a great place and it is a good time to join. Please reach out if you want to chat about the opportunity!

Finally out! 🥳 Our paper showing how a transposable element (TE) insertion can cause developmental phenotypes is now published @natgenet.nature.com 🧬🦠🐁
Below is a brief description of the major findings. Check the full version of the paper for more details: www.nature.com/articles/s41588-025-02248-5
The work was led by my inspiring PhD student Fereshteh Dorazehi and ably supported by a team of wonderful scientists over many years! Fereshteh and I have presented/will present the story at some recent and upcoming meetings and are happy to hear feedback. For now it's time for summer holidays! 9/9
Second, the factor directing human L1 methylation in early development was unknown - a deletion in the ancestral promoter is thought to evade silencing by the KRAB-ZNF/TRIM28 system. We show MORC2 is critical here, at least for those most dangerous elements transcribed in the pluripotent state. 8/X
First, MORC2 ATPase mutations cause severe developmental disorders: we explain how ATPase activity is coupled to chromatin binding and CpG methylation patterning of different targets. That many of the hyperrepressed genes encode KRAB-ZNFs, themselves TE silencers, is conceptually fascinating! 7/X
Apart from relating human genetic L1 activation to a clear cellular phenotype in development cell models, we are excited about these results for two main reasons...
6/X
Genetic loss of L1 silencing due to MORC2 mutation had severe consequences on cellular fitness in a 2D NPC model after pluripotency exit - rescued upon L1 CRISPRi! (shout out to @anitaada.bsky.social @jakobssonlab.bsky.social for the vector - see www.biorxiv.org/content/10.1... ) 5/X
Explaining the persistence of these transcriptional phenotypes we found striking loss of CpG methylation over the youngest human- and hominoid specific L1s (including polymorphic alleles), and hypermethylation of gene promoters. 4/X
Modelling these effects in pluripotent stem cells, we observed loss of function (transcriptional activation) at L1s and gain of function (transcriptional repression) at promoters, an effect which persisted upon differentiation to neural progenitors. 3/X
We engineered mutations to figure out requirements of MORC2 binding to its distinct chromatin targets. Accumulation of MORC2 at L1s and other broad targets requires reversible ATP-dependent dimerization, whereas engagement of gene promoters does not. Mutation misdirects MORC2 onto promoters. 2/X
Very proud of this work where we define how the MORC2 ATPase directs CpG methylation of active human L1 transposons in early development.
