Surprising finding that standard chemo treatment induces resistance to menin inhibitors in AML. Published in @ISEHSociety journal Exp. Hem:
exphem.org
Inhibitors of the menin-KMT2A interaction are promising agents for the treatment of KMT2A-rearranged leukemias. We evaluated menin inhibition in patient-derived xenografts of KMT2A-rearranged...

My institute @EinsteinMed kindly featured our recent paper presenting a new model for regulating hematopoietic stem cell numbers.👇Many thanks for showcasing our work so clearly! @SteidlUli @Gritsman_lab @EinsteinCellBio @Einstein_SCI

Please check out this thread on our latest paper in @Nature on HSC pool size regulation. https://t.co/hJLrLYXXEG Phenomenal collaboration with the one and only @Gritsman_lab, and driven by the outstanding @ShoTakeishi! @EinsteinCellBio @Einstein_SCI @EinsteinMed
Excited to share our latest work @Nature! We show that the total number of hematopoietic stem cells (HSCs) in the body is restricted, challenging the classical model that HSC numbers are determined locally by the niche and introducing a new paradigm. (1/9) https://t.co/kvFqNQ8Nxb

Thrilled that our paper is finally in press @ScienceMagazine!! *Platelets sequester cell free DNA, including free fetal and tumour-derived DNA* Tweetorial from @l_cmurphy below. Check out the news feature https://t.co/r1bXqfpPSU and terrific editorial from Dennis Lo
science.org
The cells could be a new source of tumor DNA for liquid biopsies
🚨 New paper alert! 🚨 I’m thrilled and proud to share that our latest work has just been published in @ScienceMagazine! 🎉 🧽 📖 Read our paper here: https://t.co/CvYSNq2nHj 🎬 Watch a summary: https://t.co/qvuZR3reTj 🧵 Or keep reading for the key points! 🔑 1/19

Check out our new preprint on an epigenetic resistance mechanism to PI3 kinase inhibition in AML and a new combination therapy with an EZH1/2 inhibitor that depletes leukemic stem cells! Great effort by @TheHematoPoet and the whole team
So excited to share a pre-print of my thesis work! Check it out to see how we can leverage an epigenetic resistance mechanism to PI3K inhibitors to target leukemic stem cells!! (Spoiler alert: PRC2 is involved!) Really proud of this work conducted with @Gritsman_lab
