Fig. 7From: The dynamic cellular and molecular features during the development of radiation proctitis revealed by transcriptomic profiling in mice P53 is specifically activated in the acute phase in mouse RP. IHC staining was performed in the rectal tissues of mice at control and irradiated groups using anti-p53 antibody. Representative images of p53 staining of the tissue sections from control (4 h) and irradiated mice at the indicated time points are shown. Scale bars, 50 μmBack to article page
