Interaction with Human Bronchial Epithelial Cells in vitro Affects Gene Expression in Moraxella catarrhalis

ABSTRACT: In this study, DNA microarray technology was used to measure global gene expression in M. catarrhalis cells that had attached to human bronchial epithelial cells in culture. M. catarrhalis ATCC 43617 was allowed to attach (MOI~30) to a monolayer of 16HBE14 human bronchial epithelial cells for 2 hr in OmniTray cell culture plates. Additional portions of these bacteria were incubated in tissue culture medium in 75-cm2 cell culture flasks in the absence of 16HBE14 cells for 2 hr. After this incubation period, the medium in the flask with the 16HBE14 monolayer was decanted and replaced with tissue culture medium containing 25 mM sodium azide (to protect RNA). The 16HBE14 monolayer and attached bacteria were released from the plastic by scraping. After low-speed centrifugation to collect the
