Transcription profiling by array of human amnion epithelial FL cells treated with the carcinogen BPDE at low concentration

ABSTRACT: The environmental carcinogen, (±)-anti-benzo[a]pyrene-7,8-diol-9,10-epoxide (BPDE), causes bulky-adduct DNA damages, triggers certain signaling pathways, and elicits gene expression changes. Here, we focused on the temporal gene expression changes induced by a low concentration (0.05 µM) BPDE in human amnion epithelial FL cells. Differential gene expression profiles at 1, 10 and 22 h post BPDE treatment were obtained using Affymetrix HG-U133 Plus 2.0 oligonucleotide microarrays. A cohort of gene expression changes related to cell cycle progression, cell growth or apoptosis, stress response, and post-transcriptional regulation was validated with quantitative real-time RT-PCR. The alteration of several cell cycle-related genes was correlated and possibly contributed to the cell cycle arrest
