The significance of the first FDA-approved PROTAC lies not in proving that targeted protein degradation is superior to conventional therapies, but in proving that degrading proteins is possible as a therapeutic go.nature.com/4x3NYt7
Our paper is now out in @natcellbio.nature.com! @craigmcrews.bsky.social

We identify a new regulator of the quality control system that protects one of nature's most important molecular machines: the ribosome. QC failure → unmitigated metabolic stress & cell death.
We identify novel catalytically impaired PARP1 mutants and show that the toxicity of some variants in cells can be rescued by the PARP inhibitor saruparib. Thus, in specific contexts, saruparib plays a pro-survival role rather than a cytotoxic one.

“In other words, unwritten science is not just incomplete; it simply does not exist for the purposes of the field. When you look at it this way, the job of a scientist - having ideas, testing them, and persuading others they are right - turns out to be, fundamentally, an act of writing.”
Doing the periodic cleaning of used plasmid miniprep columns and realized in honor of Earth Day it may be worth reminding you molecular biologists:
Plasmid miniprep columns can be cleaned and reused essentially indefinitely! Just add 1 M HCl, soak overnight and wash 3x w/ water. Save $ and plastic
Could the #ribosome be a selfish element? @mkrupovic.bsky.social & Eugene Koonin propose that the #evolution of life can viewed as a ribosomal takeover, where the ribosome evolved to consume most of the cell’s resources.

Excited to finally share our preprint on mapping the genetic interaction network of the DNA damage response with combinatorial knockout screens led by Sam Hayward, Alina Vaitsiankova, and Tomas Lama-Diaz! www.biorxiv.org/cgi/content/...

Douglas et al. study the E3 ligase HOIL-1, mutated in patients with a type of myopathy. Mutant HOIL-1 influences the sensitivity to disulfidptosis initiated by ZAKα–ATF4 in glucose starvation and inte...
Schützenhofer et al. show that expression of catalytically impaired PARP1 mutants
is toxic to cells, which can be overcome by treatment with saruparib, a PARP1-specific
inhibitor that displays a pro-r...
In this Essay, the evolution of life is construed as a ribosomal takeover, whereby the ribosome evolved to consume most of the cell’s resources, while other cellular componentry ensured the…
The DNA damage response (DDR) is a complex network of cellular pathways that ensures the faithful maintenance of our genomes upon a wide array of genomic insults. To elucidate the functional architect...
