Absolutely thrilled π£ to share our preprint π¨οΈ: "Mapping active cis-regulatory elements from transcription initiation eventsβ.
www.biorxiv.org/content/10.6...
We introduce nucCAGE and PRIME to identify active cis-regulatory elements (CREs) and disease-associated, non-coding variants.
Visualising heteroplasmic mitochondrial DNA variants in situ? Now out as #mtDNA-smFISH in @cp-devcell.bsky.social! We find purifying selection against pathogenic mtDNA variants through genetic bottlenecks in the germline and the developing brain. www.cell.com/developmenta...
We can't distinguish single-nucleotide variants (yet), but do visualise mtDNA deletions and distinguish D. yakuba from D. melanogaster mtDNA at single-molecule level in situ, in whole-mount tissue and human cells. Do give it a try, and let us know how it works in your hands and model systems!

Great to bring together 70+ researchers & partners at the LifeArc Centre for Rare Mitochondrial Diseases Annual Meeting in Cambridge last week!
From scientific updates and flash talks to patient voice discussions it was a day full of insight and collaboration!
Really pleased to see this out @natsmb.nature.com: www.nature.com/articles/s41.... MitoPerturb-Seq combines #singlecell#CRISPR screening with whole-cell Multiome, to identify nuclear modifiers of mtDNA dynamics. @mitocamb.bsky.social@mrc-mbu.bsky.social@prudentlab.bsky.social and Stephen Burr
Fantastic to join the #EdinburghScienceFestival with our labβs Stitch and Fly workshop!
We had a highly interactive, fully booked session discussing our research alongside fruit fly-inspired stitching!
Huge thanks to the PhD students in our lab and SBS public engagement team.

Doing all this at single-cell resolution allowed high-throughput, and was essential to capture the mosaic nature of mtDNA. Hopefully #MitoPerturb-Seq will lead to discovery of novel mtDNA maintenance and quality control genes, and solve cell-type specific vulnerabilities to #mitochondrialdisease.
Using #DamID-seq, we found that only ~1/3 of the differentially-expressed genes was directly bound by the canonical stress-response transcription factor Atf4, with many more factors identified by #SCENIC for future exploration.
Simultaneous RNA- and mtDNA-sequencing also allowed analysis of mtDNA replication throughout the cell-cycle, which we find to be fully relaxed. However, depletion of mtDNA results in cell-cycle slowing across all cell-cycle stages, and not just the G1-S checkpoint.
We build on CROP-seq #CRISPR screening, whole-cell ATAC-seq and 10xGenomics Multiome protocols from @leifludwig.bsky.social@caleblareau.bsky.social, and mtDNA and gRNA enrichment approaches, to study how nuclear gene perturbations impact mtDNA heteroplasmy and copy number in mouse fibroblasts.
Perturbation of Tfam, Opa1 or Polg caused mtDNA depletion, which increased heteroplasmy variance. Maybe not so surprising, but simultaneous RNA-seq then allowed us to study the single-cell transcriptional response to mtDNA depletion, which was much stronger to Opa1, than to Tfam or Polg gRNAs.
Launched to a positive reception in parliament yesterday, a new report β More trials, better data, faster access β outlines policy changes that would have huge impact for people with rare diseases.

We probably shouldnβt have favourites amongst projects in the lab, but this one was mine. Iβm so pleased we can finally share it:
Our work is now out in Nature Communications:
π nature.com/articles/s41467-025-67692-7
Excited to share our first bioinformatics contribution! π Led by Niek Wit in collaboration with the van den Ameele lab @jellevda.bsky.social , we developed DamMapper damid-seq.readthedocs.io/en/latest/, a workflow for DamID-seq analysis, to map SET1B and HIF-1 chromatin occupancy. rdcu.be/eK2TS
Bluesky, I am pleased to present to you the main product of postdoc work, published in @science.org βοΈ
As it turns out, the very quality control mechanism that can remove mutant mtDNA copies is the one that maintains high mutant burden, or heteroplasmy levels
π’ BREAKING NEWS!
The first ever treatment for a mitochondrial disease has been approved for use by NHS England! Idebenone is now available for LHON patients
A huge milestone for the mito community! π₯

Welcome to the new serie of Cambridge Fly Club meetings. We organise several events every year to foster collaboration and maintain a positive dynamic between Drosophila groups in Cambridge.
We spent a great afternoon at the House of Lords for the launch of the @lifearc.bsky.social Centre for #Rare#Mitochondrial Diseases, supported by @mdukcharity.bsky.social The event centre hosted staff, dignitaries, patients, MPs & those involved in rare disease policy & research. We even unveiledβ¦
Yesterday we were proud to join the launch of the LifeArc Centre for Rare Mitochondrial Diseases - a major step forward in mito research
We led a workshop on making complex science clear β because involving patients is key to success

Our new preprint is out! We optimized our open-source platform, HyDrop (v2), for scATAC sequencing and generated new atlases for the mouse cortex and Drosophila embryo with 607k cells. Now, we can train sequence-to-function models on data generated with HyDrop v2!
