1 Quercetin suppresses DNA double-strand break repair and enhances the radiosensitivity of human ovarian cancer cells via p53-dependent endoplasmic reticulum stress pathway. Quercetin tumor protein p53 Homo sapiens
2 However, the role of tumor suppressor p53 on quercetin"s radiosensitization and regulation of endoplasmic reticulum (ER) stress response in this process remains obscure. Quercetin tumor protein p53 Homo sapiens
3 Here, quercetin exposure resulted in ER stress, prolonged DNA repair, and the expression of p53 protein; phosphorylation on serine 15 and 20 increased in combination with X-irradiation. Quercetin tumor protein p53 Homo sapiens
4 Knocking down of p53 could reverse all the above effects under quercetin in combination with radiation. Quercetin tumor protein p53 Homo sapiens
5 In human ovarian cancer xenograft model, combined treatment of quercetin and radiation significantly restrained the growth of tumors, accompanied with the activation of p53, CCAAT/enhancer-binding protein homologous protein, and gamma-H2AX. Quercetin tumor protein p53 Homo sapiens
6 Overall, these results indicated that quercetin acted as a promising radiosensitizer through p53-dependent ER stress signals. Quercetin tumor protein p53 Homo sapiens
