How do cells sort which RNAs to keep or destroy? New preprint from THJ, Brenneke and Plaschka labs shows that export and decay machineries (TREX2/PAXT) both recognise UAP56-bound RNAs. Whether they’re exported or degraded depends on where in the nucleus this happens.

Molecular basis of polyadenylated RNA fate determination in the nucleus
Eukaryotic genomes generate a plethora of polyadenylated (pA+) RNAs, that are packaged into ribonucleoprotein particles (RNPs). To ensure faithful gene expression, functional pA+ RNPs, including prote...

This is an amazing opportunity to join the plant sciences faculty in the Oxford Department of Biology!

I am so impressed with the quality and collegiality of these colleagues. I’m not on the committee, but I’m happy to answer questions as I can.

My lab's very first manuscripts are out!!!!

- We identified nearly 60 conserved RNA structures in plastids #chloroplast #RNA
- We found that transcriptional response to warm temperatures in whole seedling is confounded by response at organ level #thermomorphogenesis

This is definitely worth reading
Mary K Gaillard, a theorist who had a knack for telling experimental physicists where to look, died in her home on May 23 at 86.

Dr. Gaillard was an unpaid scientist at CERN for more than a decade, & the first woman physicist hired & tenured at Berkeley:

Happy to share our latest preprint doing low cell number (mini-bulk) and single cell #proteomics on tumour associated neutrophils from human glioblastoma where we find multiple functional states that would be invisible to scRNAseq, some showing pro-tumoural states with potential therapeutic value
Single cell proteomic analysis defines discrete neutrophil functional states in human glioblastoma
Neutrophils are vital innate immune cells shown to infiltrate glioblastomas, however we currently lack the molecular understanding of their functional states within the tumour niche. Neutrophils are k...

Finally out!
I’m thrilled to share our new paper (Wolin et al., Cell 2025).

This paper describes SPIDR, a high-throughput method for mapping RBP binding sites.

By combining #SPIDR with #cryoEM, we identified the exact binding site of LARP1 within the #mRNA channel of the 40S ribosomal subunit.

New preprint! We solve a mystery you didn't know existed. Mitotic cells lack new transcription but require ongoing translation. Interphase mRNA half life is only 2-4 hrs. So how do cells arrest in mitosis for hours without depleting their transcriptomes?

Global inhibition of deadenylation stabilizes the transcriptome in mitotic cells
In the presence of cell division errors, mammalian cells can pause in mitosis for tens of hours with little to no transcription, while still requiring continued translation for viability. These unique...
