Fig. 2. Effect of different citrus peel extracts on the protein and mRNA levels of COX-2 and iNOS in LPS-activated RAW 264.7 cells. (A) Immunoblotting results of COX-2 and
iNOS. (B) Quantitative results of COX-2 protein levels in cells treated with 1 mg/ml of different citrus peel extracts and 1 lg/ml of LPS. (C) Quantitative results of iNOS protein
levels in cells treated with 1 mg/ml of different citrus peel extracts and 1 lg/ml of LPS. (D) RT-PCR results of COX-2 and iNOS. (E) Quantitative results of COX-2 mRNA levels.
(F) Quantitative results of iNOS mRNA levels. The values are expressed as means ± SD of triplicate tests. Means not sharing a common letter were significantly different
(p < 0.05) when analyzed by ANOVA and Duncan’s multiple range test.
