Lysosomal membrane homeostasis and its importance in physiology and disease Nature Reviews Molecular Cell Biology, Published online: 04 August 2025; doi:10.1038/s41580-025-00873-wLysosomes degrade cellular components, and their membrane is an important signalling hub. Recent insights into the mechanisms that maintain lysosomal membrane homeostasis β€” including the interplay between membrane damage, repair, lysophagy and lysosome biogenesis β€” highlight their importance in physiology, in disease and during ageing.

Protein language models reveal evolutionary constraints on synonymous codon choice Evolution has shaped the genetic code, with subtle pressures leading to preferences for some synonymous codons over others. Codons are translated at different speeds by the ribosome, imposing constrai...

This preprint from Helen Sakharova is one of the coolest things to come out of my lab: β€œProtein language models reveal evolutionary constraints on synonymous codon choice.” Codon choice is a big puzzle in how information is encoded in genomes, and we have a new angle. www.biorxiv.org/content/10.1...

🚨Preprint alert 🚨

We identify riboflavin (vitamin Bβ‚‚) as a key modulator of ferroptosis sensitivity via stabilizing FSP1 & recycling lipid-soluble antioxidants.

Excited to share our new preprint, led by Kirandeep Deol! 🀩 Genetic screens uncover mechanisms regulating FSP1 abundance in cancer. Vitamin B2 metabolism promotes FSP1 stability via FAD synth / binding, further linking nutrient metabolism to ferroptosis.
