📢📢📢 There's still time to submit your abstract!!!! Showcase your science and enjoy the company of your colleagues at this year's @isehsociety.bsky.social meeting! iseh.org/Annual-Meeting

Our newest preprint is now online! We lift up the hood on TET2 mutant clonal hematopoiesis and show that oxidative metabolism is a critical feature of TET2 deficient HSPC - in mice and humans. We also find compensatory control of redox state is a key selective mechanism and potential vulnerability.

Our study examining the role of the nicotinamide salvage pathway in #MDS and its potential for therapeutic exploitation is now available as a preprint: www.biorxiv.org/content/10.6... Thanks to our collaborators and funding from Evans Foundation and Blood Cancer United!

The Nicotinamide Salvage Pathway is a Metabolic Vulnerability of High-Risk MDS Stem Cells

High-risk myelodysplastic syndrome (HR-MDS) is a malignant clonal disorder originating in hematopoietic stem and progenitor cells (HSPCs). The current standard of care for HR-MDS patients is hypomethy...

#ASH25: Did you know that clonal hematopoiesis affects at least 20% of adults over 60? Cancer Center's @ericpietras.bsky.social, PhD, shares his insights on the role of this condition in cancer and aging at the 2025 American Society of Hematology Presidential Symposium ⬇️ https://bit.ly/3KOKdoi

Rewriting the Rulebook of Blood

At ASH 2025, Eric Pietras, PhD, highlights how aging, inflammation, and metabolism drive clonal hematopoiesis—and shape cancer and cardiovascular risk.

So proud of Dr. Sweta Patel, who gave a fantastic #ASH25 talk about her science in high-risk myelodysplastic syndrome. Way to go Sweta!

We also want to recognize three past ACS grantees who were invited speakers during marquee symposia during #ASH25: - Dr. Scott Armstrong MD, PhD (ASH-EHA Joint Symposium) - Dr. @ericpietras.bsky.social (ASH Presidential Symposium) - Dr. John DiPersio (ASH Presidential Symposium) Congrats all! 🧪

What an awesome stem cell session speaker group for #ASH25 Workshop on Myeloid Development @vangalenlab.bsky.social @thekinglab.bsky.social @paralkarlab.bsky.social Sandra Pinho and Allison Yeh (love the photobomb!)

ASH is coming! Excited to present alongside Vikram Paralkar, Sandra Pinho, Peter Van Galen, and Alison Yeh at the stem cell session of the myeloid workshop on Friday. @ericpietras.bsky.social will be moderating— don’t miss it!

@bff.fm is 12 years old this week! I've had the pleasure to be a DJ at this awesome radio station for over 11 of those. Like any community media, BFF.fm is a nonprofit and relies on its listeners and fans for support. Head on over to BFF.fm/12years and celebrate with us!

Big thanks to @cuanschutz.bsky.social for a profile of our lab's trained immunity work in autoimmune disease. March is #AutoimmunityAwarenessMonth and a good time to consider the importance of NIH @altnih4science.bsky.social and the agencies supporting such work. news.cuanschutz.edu/news-stories...

Do Stem Cell ‘Memories’ Trigger Autoimmune Disease Flare-Ups?

New research raises the possibility that 'memories' held within blood stem cells may trigger autoimmune disease flares over a person’s lifetime.

This is just a phenomenal new record from Jefre Cantu-Ledesma - really shakes up some of his well-worn tropes toward drone-inflected music by adding a talented cast of musical collaborators. Utterly immersive. Worth getting on vinyl. jefrecantu-ledesma.bandcamp.com/album/gift-s...

Since the new year, I've protected some time to get back in the lab and do science. With all the noise and confusion out there it's a wonderful experience to get focused and make some impactful discoveries again. A great reminder of why we do this.
