Figure 5: Protein expression of NF-κB (p65 and p50 subunits) and JNK and activity level of ATF6 in mouse liver following intense exercise exposure with or without quercetin treatment. p65 (a) and p50 (b) subunit protein expression, ATF6 activity (c), and JNK protein expression (d) in nuclear fractions were determined. Three independent mouse liver isolations were performed for the protein measurements, in addition to the eight for ELISA. Significant differences are indicated by the different letters. A: versus Ct; B: versus Ex.
