1 Survivin and p53 modulate quercetin-induced cell growth inhibition and apoptosis in human lung carcinoma cells. Quercetin tumor protein p53 Homo sapiens
2 However, the regulation of survivin and p53 on the quercetin-induced cell growth inhibition and apoptosis in cancer cells remains unclear. Quercetin tumor protein p53 Homo sapiens
3 In this study, we investigated the roles of survivin and p53 in the quercetin-treated human lung carcinoma cells. Quercetin tumor protein p53 Homo sapiens
4 Subsequently, quercetin increased the levels of total p53 (DO-1), phospho-p53 (serine 15), and p21 proteins, which were translocated to the nuclei in A549 cells. Quercetin tumor protein p53 Homo sapiens
5 Subsequently, quercetin increased the levels of total p53 (DO-1), phospho-p53 (serine 15), and p21 proteins, which were translocated to the nuclei in A549 cells. Quercetin tumor protein p53 Homo sapiens
6 Treatment with a specific p53 inhibitor, pifithrin-alpha, or transfection of a p53 antisense oligodeoxynucleotide enhanced the cytotoxicity of the quercetin-treated cells. Quercetin tumor protein p53 Homo sapiens
7 Treatment with a specific p53 inhibitor, pifithrin-alpha, or transfection of a p53 antisense oligodeoxynucleotide enhanced the cytotoxicity of the quercetin-treated cells. Quercetin tumor protein p53 Homo sapiens
8 Together, our results suggest that survivin can reduce the cell growth inhibition and apoptosis, and p53 elevates the p21 level, which may attenuate the cell death in the quercetin-treated human lung carcinoma cells. Quercetin tumor protein p53 Homo sapiens
