KDM6B-dependent epigenetic programming of uterine fibroblasts in early pregnancy regulates parturition timing in mice
Parturition timing in mice is controlled by locus-specific adjustment of histone H3 trimethyl lysine 27 (H3K27me3) levels within uterine fibroblasts in early gestation, with subsequent locus-specific ...

Targeting FOXM1 condensates reduces breast tumour growth and metastasis - Nature
The transcription factor FOXM1 forms functional condensates, the formation of which can be targeted with a specific peptide to suppress breast cancer growth and metastasis.

Y'all, there is now a Paperpile extension for Word. This should be useful for a lot of us who have heavy Word users and heavy Google Doc users on the same writing teams. paperpile.com/word-plugin/

1/ In March 2023, I received a lumbar puncture. This was key to receiving my chronic inflammatory demyelinating polyneuropathy #cidp diagnosis. This 🧵 is on my experience with identifying and treating #autoimmunedisease. I'll also be sharing some 🧵s I posted previously on the Other Place.

Researchers identified one key breakthrough for GLP-1 drugs in the 1980s, but Pfizer walked away.

We designed MS2 and PP7 binding coat proteins that are degraded in cells except when bound by their hairpin RNAs. You can check out our pre-print here: tinyurl.com/27p7hyt9, and listen to a Google AI-generated podcast on it here: notebooklm.google.com/notebook/d71...

We did this crazy project where we tried to see if proteins could interact with their mirror image ligand. Seems impossible when proteins need to form 3D structures to interact. But what about if the interaction remains disordered??? www.nature.com/articles/s41...

Stereochemistry in the disorder–order continuum of protein interactions - Nature
Studies on protein–protein interactions using proteins containing d- or l-amino acids show that stereoselectivity of binding varies with the degree of disorder within the complex.

snoRNA-facilitated protein secretion revealed by transcriptome-wide snoRNA target identification
Transcriptome-wide mapping of snoRNA targets reveals mRNA-snoRNA-7SL RNA ternary interactions, which facilitate nascent protein translocation to the ER and subsequent secretion.

Came to a new understanding of 'colocalization' since starting STED microcopy: there is no colocalizaiton, objects cannot occupy the same physical space!

How long does an mRNA stay in the nucleus? How long does it stay in the cytoplasm? In an amazing collaboration with @landthalerm.bsky.social, we used metabolic labeling, cell fractionation and mathematical modeling to quantify mRNA flow through the cell. Finally out in MSB: doi.org/10.1038/s443...
Graphical abstract of the paper.

I’m thrilled to share a collaborative story from @Mendell_lab and Jan Erzberger labs, led by postdoc extraordinaire Xiaoqiang Zhu. We showed that in addition to their canonical decoding function, tRNAs play a key role in regulating mRNA stability during translation! www.science.org/doi/10.1126/...
science.org
Specific tRNAs promote mRNA decay by recruiting the CCR4-NOT complex to translating ribosomes
The CCR4-NOT complex is a major regulator of eukaryotic messenger RNA (mRNA) stability. Slow decoding during translation promotes association of CCR4-NOT with ribosomes, accelerating mRNA degradation....

A report made counterintuitive claims that PRC2 binds → more RNA than PTBP1 & hnRNPU → RNAs that do not exist in the cell We found a simple explanation: the authors ignore most RNA in the sample, leading to inflated background & misleading conclusions. www.biorxiv.org/content/10.1...
biorxiv.org
Failing to account for RNA quantity inflates background and leads to the misleading appearance that PRC2 and GFP bind to RNA in vivo
We recently published biochemical and quantitative evidence that challenges the widespread claims that PRC2 binds directly to many RNAs in vivo . A recent preprint performs a re-analysis of some of ou...

Missed the woodpecker sweep by 1 at Green-Wood Cemetery this morning. Tallied Yellow-bellied Sapsucker, Red-headed Woodpecker, Red-bellied Woodpecker, Downy Woodpecker & Northern Flicker. Oddly, Hairy Woodpecker is rare here despite breeding at nearby Prospect Park #birds #birdsNYC

REX - a mammalian "range extender" element that can turn short-distance enhancers into long-distance enhancers. New preprint from a collaboration led by Grace Bower and Evgeny Kvon. doi.org/10.1101/2024...
Schematic overview of the proposed mode of action of the newly discovered REX element. Top: An enhancer can activate a gene at a short distance, but not at at long range. Middle: Presence of (C/T)AATTA motifs within an enhancer enable it to act over long distances. Bottom: Coupling a short-range enhancer to the REX element containing the same motifs turns it into a long-range enhancer.

I've been meaning to write a lengthy thread about our experiences with DNA methylation editing in mouse ESCs if that would be useful (or interesting?) for a niche audience here. tl;dr: it was frustrating but we learned a lot, and it ended with our shiny new pub (1/17) www.nature.com/articles/s41...
