Excited about Kolya Aleksashin's new work, enabling preparation of active in vitro translation systems from primary human cells and difficult-to-edit cells (fibroblasts and cardiomyocytes). This opens new opportunities to probe mechanisms of translation regulation.

Not all RelE toxins are created equally. RelE1, E2 cut 16S rRNA, RelE3 degrades mRNA in a ribosome-dependent manner. #MicroSky #Ribosome 🧪 #RNASky ⬇️
Two M. tuberculosis RelE toxins don’t cut mRNA, they slice 16S rRNA itself, shutting down translation in a totally unexpected way, new study reveals.
A big leap in understanding TB’s survival tricks and new angles for therapies.
