Fig 2. Inhibition of AR prevents LPS-induced expression of inflammatory marker proteins.
Growth-arrested hNPECs were preincubated with sorbinil or zopolrestat for 24 h followed by treatment with LPS (1 μg/ml) and incubation for additional 24 h. At the end of incubation, cells were lyzed and equal amount of protein (40 μg) was separated on SDS-PAGE followed by immunoblotting using antibodies against COX-2, iNOS, and ICAM-1. Immunoblotting of the stripped membranes with GAPDH antibodies was used to depict equal protein loading. Numbers below the blots show fold changes in the expression of proteins (n=3). sorb, sorbinil; zopol, zopolrestat.
