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. journals.plos.org/plosgenetics... 🧬⚡

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.

📢 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. www.nature.com/articles/s41...

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)

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...

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!🧪🧶🧬🌾
