Today we’re announcing X-Cell — Xaira’s first step toward a virtual cell. 🧬 A foundation model that predicts how gene expression changes under causal perturbations — across cell types, conditions, and even unseen biology. This is not trained on observational atlases. It is trained on interventions. 🧵👇

New @NatureGenet paper by @ciacobu @MSKCancerCenter on genomic evolution of #PancreaticCancer at single cell resolution. Genomic heterogeneity of KRAS allelic balance likely explains a lot of de novo heterogeneity in response to KRAS inhibitors. nature.com/articles/s41588-0…

The ability to detect and assess cell-free tumor DNA will keep getting better, ultimately making "liquid biopsy" a standard of early detection and care. A new report @CellCellPress today highlights progress in tDNA sequencing value for a form of lung cancer cell.com/cell/fulltext/S0092… @CharlesSwanton

Congratulations to @nicholas_navin @MDAndersonNews and the @humancellatlas team for mapping the panorama of the “normal” breast epithelium. And surprise, surprise: Normal breast tissues harbour rare populations of aneuploid epithelial cells nature.com/articles/s41586-0… Mean ~3% Increase with age Harbor “pathogenic” alterations Associated with specific epithelial lineages Congratulations Nick & team!

ecDNA are rogue genetic material that amplify genes, contribute to treatment resistance and drive genomic heterogeneity. We report on the Origins and impact of extrachromosomal DNA today in @Nature nature.com/articles/s41586-0…

Thrilled to share our paper published in @Nature, where we uncover a new process of tumor initiation through a polyclonal-to-monoclonal transition at the @precancerous stage. So proud of my fantastic team (led by @ZhaolianLu ) and incredible collaborators! nature.com/articles/s41586-0…

Great to see the preprint from @owen_sansom published in @CR_AACR KRAS Loss of Heterozygosity Promotes MAPK-Dependent #PancreaticCancer Initiation and Induces Therapeutic Sensitivity to MEK Inhibition aacrjournals.org/cancerres/a… In the KRAS inhibitor era, these findings on the wild type allele status have implications for patient stratification & treatment responses.

💡Will #ctDNA serve as a treatment response biomarker in metastatic cancers? Here’s a thorough evaluation in @CCR_AACR from the RECIST working group, looking at the next steps towards using ctDNA for novel early endpoints in clinical trials and beyond. 👉 doi.org/10.1158/1078-0432.CC…

Pancreatic cysts are often found incidentally on imaging tests for other indications. Imaging, symptom assessment, and laboratory tests can help distinguish benign cysts from those associated with a risk of malignant transformation. Learn more: nej.md/4g4jz5s

New preprint from @ciacobu @CpcrMsk Genomic evolution of #PancreaticCancer at single-cell resolution biorxiv.org/content/10.1101/… @EileenMOReilly @CentralParkWMD @benjraphael This study sequenced 137,491 single-nucleus DNA libraries from 24 pancreatic cancers, including primary tumors, metastatic cancers from rapid autopsy samples, and longitudinal samples from patients who had recurrence. Incredible dataset mapping evolutionary trajectories in this cancer.
