The hyperproliferation of vascular smooth muscle cells underlies many vascular diseases. Here Xieet al. show that the splicing factor SRSF1 is an endogenous stimulator of human and mouse aortic smooth muscle cell proliferation via the Δ133p53/EGR1/KLF5 signalling axis, identifying potential therapeutic targets for vascular proliferative disorders.
