Transcription profiling of human normal human bronchial epithelial (NHBE) cells exposed to whole cigarette smoke over a time series to study the impact of tobacco exposure

ABSTRACT: Gene expression patterns were assessed in normal human bronchial epithelial (NHBE) cells exposed to cigarette smoke (CS) from a typical "full flavor" American brand of cigarettes in order to develop a better understanding of the genomic impact of tobacco exposure, which can ultimately define biomarkers that discriminate tobacco-related effects and outcomes in a clinical setting. NHBE cells were treated with CS for 15 minutes and alterations to the transcriptome assessed at 1,2,4 and 24 hours post-CS-exposure using high-density oligonucleotide microarrays. Experiment Overall Design: Cells were exposed to smoke or air (“mock-exposed”) for 15 min, after which they were refed with fresh media and allowed to incubate for 1h, 2h, 4h or 24h. Smoke and mock samples were compared at each time
