1 In utero exposure to benzene increases embryonic c-Myb and Pim-1 protein levels in CD-1 mice. Benzene proviral integration site 1 Mus musculus
2 We hypothesize that in utero exposure to benzene may cause leukemogenesis by affecting the embryonic c-Myb/Pim-1 signaling pathway and that this is mediated by oxidative stress. Benzene proviral integration site 1 Mus musculus
3 Our results show increased oxidative stress at 4 and 24 h after exposure, increased phosphorylated Pim-1 protein levels 4 h after benzene exposure, and increased Pim-1 levels at 24 and 48 h after benzene exposure. Benzene proviral integration site 1 Mus musculus
4 Our results show increased oxidative stress at 4 and 24 h after exposure, increased phosphorylated Pim-1 protein levels 4 h after benzene exposure, and increased Pim-1 levels at 24 and 48 h after benzene exposure. Benzene proviral integration site 1 Mus musculus
5 PEG-catalase pretreatment prevented benzene-mediated increases in embryonic c-Myb and Pim-1 protein levels, and benzene-induced oxidative stress. Benzene proviral integration site 1 Mus musculus
6 These results support a role for ROS in c-Myb and Pim-1 alterations after in utero benzene exposure. Benzene proviral integration site 1 Mus musculus
