E. coli and S. aureus differentially regulate Keap1 degradation. (A) Cytoplasmic and nuclear proteins were extracted from cells treated with E. coli (1 × 10⁷ particles/mL), S. aureus (1 × 10⁷ particles/mL) and lipopolysaccharides (LPS) (10 μg/mL) and were analyzed by immunoblotting with anti-Keap1. GADPH and Histone are shown as loading controls, respectively. (B) A chart bar shows Keap1 levels determined with densitometry analyses after normalization to GADPH. Data are representative of three triplicates and are representative of 3 separate experiments. * p < 0.05.
