1 Induction of cytochrome P(1)450 RNA and benzo[a]pyrene metabolism in primary human hepatocyte cultures with benzanthracene. benz(a)anthracene cytochrome P450 family 1 subfamily A member 1 Homo sapiens
2 We have examined the steady-state level of RNA from the P(1)450 gene and the metabolism of benzo[a]pyrene (BP) in primary cultures of human hepatocytes exposed for up to 4 days to 12.5 microM benzanthracene (BA), and in uninduced control cultures. benz(a)anthracene cytochrome P450 family 1 subfamily A member 1 Homo sapiens
3 While the steady-state levels of RNA from the P(1)450 gene were nondetectable in uninduced (DMSO only) human hepatocytes, 12.5 microM BA-induced AHH activity, BP metabolism, and/or P(1)450-specific RNA in hepatocytes from seven human cases were investigated. benz(a)anthracene cytochrome P450 family 1 subfamily A member 1 Homo sapiens
4 While the steady-state levels of RNA from the P(1)450 gene were nondetectable in uninduced (DMSO only) human hepatocytes, 12.5 microM BA-induced AHH activity, BP metabolism, and/or P(1)450-specific RNA in hepatocytes from seven human cases were investigated. benz(a)anthracene cytochrome P450 family 1 subfamily A member 1 Homo sapiens
5 Exposure of human hepatocytes in vitro to BA leads to a large increase in the steady-state level of the RNA specific for the P(1)450 gene and an increase metabolism of BP. benz(a)anthracene cytochrome P450 family 1 subfamily A member 1 Homo sapiens
