Congrats! Impressed and proud !

Grateful to our incredible teamโ€”scientists, artists, and collaboratorsโ€”who built this story with us. We hope the science and imagery inspire new ways of seeing how leukemias take shape. @gandhardatar.bsky.social , @sciencyelmira.bsky.social , @drawimpacts.bsky.social , and others!

Even more exciting, we find that other AML driversโ€”like NUP98 and KMT2A fusionsโ€”coerce their own โ€œmajestic creaturesโ€ into the same C-body nightmare, revealing a shared structural logic behind clinically similar leukemias. See the original thread โฌ‡๏ธ for more insights.

Disparate leukemia mutations converge on nuclear phase-separated condensates Mutant NPM1 and various leukemia oncofusions form biophysically indistingishable nuclear condensates, termed C-bodies, which orchestrate leukemogenic gene expression. These findings consolidate divers...

And hereโ€™s the twist we uncover in the new work โฌ‡๏ธ: the gremlinโ€™s power was never in the cytoplasm at all. NPM1c must act *in the nucleus* through phase separation, bringing together multiple proteins on chromatin to drive AML... Overturning years of assumptions.

Now: NPM1c becomes a nestling contemplating potential destiniesโ€”(1) majesty of wild-type NPM1โ€™s eagle-like order (2) a menacing hawk that shatters the nucleus as it sparks C-body formation and unleashes HOX programs - subverting life-giving differentiation to life-taking self-perpetuation

Mutant NPM1 Maintains the Leukemic State through HOX Expression Brunetti etย al. show that specific loss of NPM1c from the cytoplasm leads to downregulation of HOX genes and differentiation in NPM1 mutant AML. Blocking NPM1c nuclear export by XPO1 inhibition reduce...

NPM1c comes from a tiny frameshift that creates a nuclear export signal in what is normally a nucleolar protein. In earlier work, we portrayed its HOX-activating force as a mischievous gremlin straining to escape the nucleusโ€”an image that captured how disruptive this mutant is.

Today's the print release of a #RibackLab and #GoodellLab collaborationโ€” weโ€™re excited to share the visual story behind the science, including the dramatic artwork that inspired how we thought about aberrant function of NPM1c - which occurs in about 1 in 3 adult acute myeloid leukemias (#AML).

Happy to share our review at Cell Stem Cell as part of their Hallmarks series. As always, a pleasure to work with friends and colleagues Anne Brunet (@brunetlab.bsky.social) and Peggy Goodell(@goodell-lab.bsky.social).

Thank you so much, Dan! Itโ€™s such a huge honor. When I started my lab more than 25 years ago, I never imagined this would be possible. I give enormous credit to being in a fantastic supportive environment and many amazing trainees who did all the hard work.
