FIG. 1.

Expression of IFN genes (A) and IFN regulatory genes (B) in AA-treated PM. PM (10⁷ cells) were seeded in 90-mm plastic Petri dishes as described in Materials and Methods. After a 24-h incubation, PM cultures were washed and treated with AA at a concentration of 1,000 μM. Total cellular RNA was then extracted 6 h later and processed for semiquantitative reverse transcriptase PCR. Results are representative of three different experiments.
