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!

Fantastic to join the #EdinburghScienceFestival with our lab’s 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. #Drosophila #Genetics

Wonderful and honoured to write a perspective with @prudentlab.bsky.social @mrc-mbu.bsky.social on such an intriguing and cool observation of beautiful mitochondrial biology! Amazing work on how pearling allows mitochondrial genome organisation by @jclandoni.bsky.social @sulianamanley.bsky.social!

Check out the fantastic perspective by @jellevda.bsky.social & @prudentlab.bsky.social on our #pearling work, out in the same @science.org issue! www.science.org/doi/10.1126/...

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.

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 – More trials, better data, faster access – outlines policy changes that would have huge impact for people with rare diseases. πŸ‘‰ Read the report now: t.ly/LJRi4

Bluesky, I am pleased to present to you the main product of postdoc work, published in @science.org ☝️ 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

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 – because involving patients is key to success #mitochondrialdisease #mitoresearch #patientvoice #raredisease

2x CRA posts extended until end of April. So you have another chance to work with #mito disease patients as part of the @lifearc.bsky.social centre for #rare #mito diseases! See links below to apply! @eastgenomics.bsky.social @camneuro.bsky.social @cuhnhs.bsky.social

πŸ“’ We have not 1 but 3 clinical/patient-facing jobs working with #mitoCAMB on the #LifeArc #raredisease centre for #mito diseases. 1x pre/post-doctoral CRA; 1x post-doctoral CRA (with potential to become a 4 year ACL); 1x research coordinator Join us! Links below.
