Heme oxygenase-1 prevents liver fibrosis in rats by regulating the expression of PPARγ and NF-κB

Figure 4 Levels of peroxisome proliferator-activated receptor gamma mRNA and nuclear factor-kappa B mRNA in rat liver analyzed by real-time polymerase chain reaction assay and associated protein assessed by Western blotting. A: Peroxisome proliferator-activated receptor gamma (PPARγ) mRNA and protein. The molecular weight of PPARγ is 55 kD; B: Nuclear factor-kappa B (NF-κB) mRNA and protein. The molecular weight of NF-κB is 50 kD. β-Actin was used as an invariant control. Values are expressed as mean ± SE (n = 4 per group). ^aP < 0.01 vs the levels in group A; ^cP < 0.05 vs the levels in group C; ^dP < 0.01 vs the levels in group C; ^eP < 0.01 vs the levels in group D. Control for equal loading.
