6 Interestingly, the p53 signaling pathway was activated by BaP, but not by TCDD, in BeWo cells and co-treatment by the p53 inhibitor pifithrin-alpha or siRNAs-mediated silencing of p53 prevented up-regulation of beta-hCG and syncytin-2 induced by BaP. Benzo(a)pyrene tumor protein p53 Homo sapiens
7 Taken together, these data demonstrate that BaP induces differentiation of placental trophoblastic BeWo cells in an AhR- and p53-dependent manner. Benzo(a)pyrene tumor protein p53 Homo sapiens
