Modulation of Arginase-2 mRNA Levels by ω-3 PUFAs and Aspirin in Asthmatic Human Lung Fibroblasts

Figure 2

The effects of RvD1 and TH1 cytokines on mRNA levels of genes involved in arginine metabolism in DHLF. ARG2 (a), ODC (b), and OAT (c) mRNA levels were determined in DHLF. DHLF were treated with 1 μM RvD1, TH1 cytokine cocktail (25 ng/mL TNF-α, 10 ng/mL IFN-γ, and 100 ng/mL IL- 1β), or both for 24 hours. RNA was then extracted from DHLF and analyzed by RT-qPCR. Data were statistically analyzed using randomized block ANOVA, followed by Tukey’s multiple comparisons test. Depicted are the mean relative mRNA for biological replicates performed in triplicate. Stars indicate significant differences determined using Tukey’s multiple comparisons test as follows: and significant difference from control.
