Figure 2. Leptin dose-dependently and differentially regulated gene expression of RAGE and AGE-R1 in activated HSC in vitro.
Serum-starved HSC were treated with leptin (100 ng/ml) as indicated. Total RNA or whole cell extracts were prepared. A. Real-time PCR analyses of RAGE and AGE-R1 mRNA. Values were expressed as mRNA fold changes (means ± SD) (n= 3). *P<0.05 vs. the untreated control (the corresponding 1st column). B. Western blotting analyses of RAGE and AGE-R1. β-actin was used as an invariant control for equal loading. Representatives were presented from three independent experiments.
