Local mitochondrial physiology defined by mtDNA quality guides purifying selection Author summary Mitochondria are essential organelles in our cells that convert nutrients into usable cellular energy. They contain their own DNA, and mutations in this DNA can compromise mitochondrial...

How do cells assess mtDNA quality?

Local ATP and membrane-potential gradients reflect mtDNA integrity and drive intracellular purifying selection.

We introduce FAST, a scalable mtDNA QC assay in S. cerevisiae.

Great collaboration with the Schmoller Lab.

Oxidative phosphorylation complexes contain subunits encoded by both the nuclear and mitochondrial genomes. How do cells coordinate the synthesis and assembly of these complexes at the inner membrane? We teamed up with Martin Ott (@mitolab.bsky.social) to address this in two recent papers.

Translational activators align mRNAs at the small mitoribosomal subunit for translation initiation Nature Structural & Molecular Biology - Mitochondrial translational activators (TAs) facilitate transcript-specific translation. Using selective ribosome profiling and cryo-electron microscopy,...

Ribonucleotide incorporation into mitochondrial DNA drives inflammation - Nature Imbalanced nucleotide metabolism leads to age- and mtDNA-dependent inflammatory responses and senescence-associated secretory phenotype in senescence.

📢 Publication Alert: We're excited to share a new study from the Langer Lab published in @nature.com! It uncovers how an excess of RNA building blocks can destabilize mitochondrial DNA, which plays a role in age-related inflammation.

HuD controls widespread RNA stability to drive neuronal activity-dependent responses Neuronal activity shapes brain development and refines synaptic connectivity in part through dynamic changes in gene expression. While activity-regulated transcriptional programs have been extensively...

Our new pre-print from the Greenberg and Churchman labs shows that activity-dependent modulation of RNA stability is a major, and underappreciated, mechanism of gene regulation in neurons. Tutorial below! www.biorxiv.org/content/10.1... (1/11)

A molecular switch at the yeast mitoribosomal tunnel exit controls cytochrome b synthesis Abstract. Mitochondrial gene expression needs to be balanced with cytosolic translation to produce oxidative phosphorylation complexes. In yeast, translati

In a new study by our @pelleeas.bsky.social, we reveal how Mrx4 organizes translational regulation of cytochrome b synthesis at the mitoribosomal tunnel exit. Thanks @kawresearch.bsky.social for funding and @stirlingchurchman.bsky.social for the fun collaboration! academic.oup.com/nar/article/...

We just returned from a great retreat with the @osman-lab.bsky.social in the Austrian alps. Intensive scientific discussions on mitochondrial gene expression, fun people, delicious food and great scenery, thank you so much everyone!

Small molecules restore mutant mitochondrial DNA polymerase activity - Nature An activator of DNA polymerase γ restores function to disease-causing mutant variants and demonstrates a potential route to treatments for inherited mitochondrial disorders involving POLG mutations.

New paper out from the Falkenberg and Gustafsson labs. Thanks to Pretzel for a successful collaboration.

@verenaresch.bsky.social did a wonderful job on the cover and animation, she really brought it to life 👩‍🎨

We're on the cover of @science.org this week. Awesome work by @florentwaltz.bsky.social. #CryoET is reaching crazy resolutions inside cells, and this is just the beginning. Fantastic interpretation of the proton motive force by @verenaresch.bsky.social. Always a pleasure making #SciArt with you!🧪🧶🧬🌾
