Hidden no longer. New work reveals that a core centromere chaperone has been conserved across animals far more broadly than we realised. Highlight of beautiful work from @jeremyahollis.bsky.social & colleagues @harmitmalik.bsky.social Lab #preLight ⬇ prelights.biologists.com/highlights/r...

Remote homology and functional genetics unmask deeply preserved Scm3/HJURP orthologs in metazoans - preLights
Hidden no longer. By peering beyond sequence similarity, this work reveals that a core centromere chaperone has been conserved across animals far more broadly than we realised.

Dr. @yarimura.bsky.social brings frogs back to Fred Hutch after a long absence to study the structure of DNA-linked molecular complexes that change during the cell cycle and malfunction in cancer and other diseases. bit.ly/3J8S5Ae

Frogs help Fred Hutch find the shape of small things
Frogs have made significant contributions to Fred Hutch science over the years as a model organism that shares much of our biology, but they've been absent from the menagerie for about two decades. Dr...

#Celegans peel-1/zeel-1 is one of the best-characterized animal #toxin-antidote systems, but how does it work? @lewsiferase.bsky.social &co show that PEEL-1 co-opts the PMPL-1 to exert toxicity by creating a novel #IonChannel that leads to cell swelling @plosbiology.org 🧪 plos.io/3HfH8LN
Selected frames of a live-cell imaging time-course experiment. A single cell is shown, co-expressing PEEL-1::eGFP and PMPL-1::mCherry. The nucleus is labeled (“N”). t = 0 is 16 hrs after transfection. Acute swelling can be seen (t = 2 hr 30 min), followed by a transient blob or protrusion (arrow) jetted out by the cell (t = 4 hr 15 min) and later reabsorbed (dotted arrow) (t = 4 hr 20 min). Scale bar = 10 µm.

Excited to share a recent preprint by Oliver Newsom, where we evaluate the functional contributions of serum for cancer cell proliferation. Inside: A broadly applicable serum-free media, Quantitative lipid uptake characterization, Evidence lipid scavenging > synthesis for cancer cell proliferation.

In the midst of the dark ages, we MUST retain optimism—keep going, keep publishing, keep talking science, and keep doing fun experiments! Our latest paper on the fascinating TF SKN-1/NRF presents exciting new findings using our one and only #Celegans #genetics #oxidativestress #proteasome

Our latest work on the ever-fascinating skn-1 transcription factor (Nrf1 and Nrf2 for non-worm people). www.biorxiv.org/content/10.1...

Protein sequence editing defines distinct and overlapping functions of SKN-1A/Nrf1 and SKN-1C/Nrf2
The Nrf/NFE2L family of transcription factors regulates redox balance, xenobiotic detoxification, metabolism, proteostasis, and aging. Nrf1/NFE2L1 is primarily responsible for stress-responsive upregu...

The best part of the week kicks off soon: Friday Afternoon Seminars! Can’t wait to learn about the latest research from Elyse Christensen in the @nlehrbach.bsky.social Lab and Liberalis Boila in Human Biology’s Kugel Lab. For all our @FredHutch.bsky.social colleagues, join us for two great talks!
Friday Afternoon Seminars (FAS), this Friday 11/22 at 4pm in Pelton.
