Oncogenic PIK3CA mutations cause lineage-selective niche corruption
Activating PIK3CA mutations occur in cancer and also non-malignant overgrowth disorders, in which marked lineage-selectivity of pathology is characteristic. Yet the basis of such context-dependent effects remains poorly understood. Here, by combining patient-derived and CRISPR-engineered iPSC models of vascular development with time-resolved, single-cell signalling and transcriptomic analyses, we…
