Fig. 5From: A positive feedback loop between ID3 and PPARγ via DNA damage repair regulates the efficacy of radiotherapy for rectal cancerAnimal experiments verified the effect of ID3 on the radiosensitivity of HCT116 and HT-29 cells. A The experimental scheme for xenograft tumor irradiation. B Images of xenograft tumors in nude mice before and after irradiation. C Images of xenograft tumors stripped from nude mice. The tumor volume was measured (D) and the tumor inhibition rate was analyzed (E). Data are expressed as mean ± SD (n = 5). *P < 0.05.
