1 We have evaluated the effects of some highly purified NDL-PCBs and benzo[a]pyrene (BP) on BP-induced Raf, Erk, Mdm2, p53 signaling and on BP-induced apoptosis and cell cycle arrest. Benzo(a)pyrene tumor protein p53 Homo sapiens
2 A dioxin-like PCB (DL-PCB 126) was used as reference and gave results that were predictable from previous studies, i.e. it attenuated BP-induced p53 response and apoptosis. Benzo(a)pyrene tumor protein p53 Homo sapiens
3 This phosphorylation promotes a cytoplasmic translocation of FoxO3a and p53 and our data suggest that NDL-PCBs may inhibit BP-induced apoptosis by preventing a FoxO3a-dependent translocation of p53 to the cytoplasm. Benzo(a)pyrene tumor protein p53 Homo sapiens
4 This phosphorylation promotes a cytoplasmic translocation of FoxO3a and p53 and our data suggest that NDL-PCBs may inhibit BP-induced apoptosis by preventing a FoxO3a-dependent translocation of p53 to the cytoplasm. Benzo(a)pyrene tumor protein p53 Homo sapiens
