Transcription profiling of mouse C57BL6J lung exposed to 2 weeks of cigarette smoke compared to age-matched controls

ABSTRACT: We hypothesize that gene expression in the cigarette smoke (CS) exposed neonatal lung and age-matched controls will be divergent. CS exposed lung will have divergence of immune response genes and structural genes. The lungs of (6) 2 week old neonatal mice exposed to 2 weeks of CS were compared to the lung of (4) 2 week old age-matched control mice. We utilized microarray analysis to examine transcriptional differences between smoke exposed neonatal lung and age-matched controls. Experiment Overall Design: This study utilizes microarray analysis to test these hypotheses. Six sets of lungs were harvested from CS exposed mice and four sets of lungs were harvested from age-matched control mice. RNA was isolated and used for global gene expression profiling (Affymetrix Mouse 430 2.0 array). Statistically significant gene expression was determined as a minimum 6 counts of 9 pairwise comparisons, minimum 1.5-fold change, and p < 0.05. Further, Absolute | FC - FC SEM | >= 1.5.
