Cytosolic proteins were prepared to determine the expression levels of NF-κB-dependent pro-inflammatory gene and adhesion molecules. Western blotting was performed to detect renal COX-2, iNOS, and 5-LOX levels in cytoplasmic extracts from aged rats (A). NF-κB-dependent Adhesion molecules levels were detected by Western blot using anti VCAM-1 and anti ICAM-1-specific polyclonal antibodies. Levels were normalized to β-actin. One representative blot is shown from 3 experiments that yielded similar results. **P<0.01, ***P<0.001 vs. normal aged rat by ANOVA.
