In the rat, expression of the CYP1A1 gene is closely associated with arylhydrocarbon hydroxylase (AHH) enzyme activity. AHH is an inducile enzyme activity known to play an important role in the bioactivation of polycyclic aromatic hydrocarbons (PAHs) to mutagenic and
To study the inhibitory effects of some agents or drugs (inhibitors) on benzo(e)pyrene (B(e)P)-induced cell death and apoptosis on human retinal pigment epithelial (ARPE-19) cells in vitro. ARPE-19 cells were pretreated with varying concentrations of different classes of inhibitors (calpain
The objective of this study was to examine the potential for a specific ligand of carcinogen binding protein (CBP) to induce changes in the overall character of hepatic microsomal cytochromes P-450 (P450) and to compare potential changes with those induced
UDP-glucuronosyltransferases (UGTs) are cytoprotective and may also be genoprotective. Since over 10% of the population have hereditary deficiencies in UGTs, this family of enzymes could constitute an important determinant of susceptibility to chemical carcinogenesis, teratogenesis, and neurodegeneration. Fibroblasts contain Phase
The present studies were undertaken to provide a rationale for the observation that benzo(a)pyrene and 2-acetylaminofluorene induce the hepatic CYP1A1 protein, whereas their non-carcinogenic isomers benzo(e)pyrene and 4-acetylaminofluorene are, at best, relatively very weak inducers. Using amino acid sequence alignment
