KRASG12V and BRAFV600E are oncogenic mutations that activate ERK signalling. Here, the authors use single cell analysis in intestinal organoids and show that BRAFV600E activates ERK in all intestinal cell types, while KRASG12V induces ERK activation in only a subset of cells, depending on cell differentiation state.
