Radiation-induced fibrosis is a severe side effect of radiotherapy. TGF-β and radiation synergistically induce expression of the profibrotic PAI-1 gene and this cooperation potentially involves p53. Here, we demonstrate that p53 is both indispensable and sufficient for the radiation effect inducing synergistic activation of PAI-1 by radiation and TGF-β.
