What happens if you delete large intronic regions? In human tissue culture cells, we found many deletions that decrease growth and some that increase it. In most cases, deletion affected expression or splicing of the gene. www.cell.com/cell-reports... 1/3

A genome-wide functional analysis of conserved intronic regions reveals essential roles for speckle-associated retained introns

Farhangmehr et al. investigate functions of highly conserved intronic sequences in cell fitness using a CRISPR-based deletion screen. Deletions in FNBP4 intron lead to changes in p53 pathway genes. De...

RESEARCH PAPER: The competition between splicing and 3′ processing shapes the human transcriptome By Soles et al. and Yongsheng Shi ➡️ https://genesdev.cshlp.org/content/40/13-14/1099.full UC Irvine UC Irvine School of Medicine #RNAprocessing #splicing #mRNA #transcription

How do 2 meters of DNA fit inside a nucleus you can barely see? 🧬 Our new study mapped individual nucleosomes inside human cells.

Great opportunity! We’re looking to hire a Platform Manager to lead the decelopment and operations of the @ircm.bsky.social RNA Therapeutics core facility. If you have solid expertise in #RNA biology, particularly in methodologies to synthesize and purify oligonucleotides, mRNA and LNPs, apply now!

Interested in RNA and proteins? Perfect! 😀 We seek to fill a fully funded 3+ years PhD position for a project on pre-mRNA splicing regulation using structural biochemistry in combination with cell biology and bioinformatics. Find more information on our lab's homepage and get in contact via e-mail!

RNA can build. A short RNA self-assembles into a 60-subunit icosahedral cage like a viral capsid, but made entirely of RNA. The striking preprint also reveals a 57-nt RNA filament at ~2.7 Å. Congratulations, Lin Huang and colleagues! www.biorxiv.org/content/10.6...

Nitric oxide drives proteomic diversity through alternative splicing

Nitric oxide drives proteomic diversity through alternative splicing

Schindler et al. report that RNA-binding proteins undergo widespread S-nitrosylation at evolutionarily conserved sites. S-nitrosylation of the master splicing regulator PTBP1 alters RNA-binding properties to reprogram the transcriptome and proteome. Nitric oxide thereby coordinates gene and protein regulation in cellular physiology and disease.

Breaking news: Indiana University plant microbiologist Roger Innes has been locked out of his laboratory by the school in response to a request by one of his federal funders. The move comes after Innes complained about the government’s prosecution of Chinese postdocs. https://scim.ag/4tsDqRr

New preprint alert! Together with Tetsuya Yamamoto at Hokkaido University, we propose a “polymer micelle” model of transcriptional bursting. www.biorxiv.org/content/10.6...

And this, of course, is not scalable. And professionalizing things is expensive.

AI produces MORE editorial labor, not less. “[To weed out slop] the journal doubled its deputy editors from 6 to 11 & nearly doubled its sr editors from roughly 30 to 60. All of this is volunteer labor, unpaid academics donating time to maintain scientific quality.“ www.forbes.com/sites/johndr...
