The molecular mechanisms leading to basal extrusion are unclear. Here, the authors use the Drosophila accessory gland to model human prostate acini and show that Ras/MAPK and PI3K/AKT/mTOR pathways are co-activated in two autocrine loops by dEGF and dIGF, inducing basal extrusion and subsequent tumour formation.
