Abstract
An in vitro system for identifying agents capable of inhibiting or preventing oxidative damage is provided. The disclosed in vitro system comprises a mouse fibroblast culture derived from a transgenic mouse capable of expressing a reporter gene regulated by a human elastin promoter and a chemical means for generating reactive oxygen species within the mouse fibroblast culture. Also disclosed is a method for using this in vitro system for identifying agents capable of inhibiting or preventing oxidative damage. The disclosed method comprises adding a test agent suspected of providing protection against oxidative damage to the mouse fibroblast culture, adding a chemical means for generation of reactive oxygen species to the culture, determining human elastin promoter activity in the culture exposed to the test agent after a selected time period, and comparing the determined human elastin promoter activity in the culture exposed to the test agent to the activity of the same promoter in a control fibroblast culture wherein a decrease in the determined human elastin promoter activity is indicative of the test agent inhibiting or preventing oxidative damage.
