Figure 1From: Increased IL-4 mRNA expression and poly-aromatic hydrocarbon concentrations from children with asthma The expression of ACSL3, IFN-γ and IL-4 mRNA in (A) whole blood from rats treated with benzopyrene and (B) peripheral blood from asthmatic patients. A: The expression of ACSL3, IFN-γ and IL-4 mRNA in whole blood from rats treated with benzopyrene. Fold difference in ACSL3, IFN-γ and IL-4 transcript levels from treated group compared to transcript level from untreated as referent = 1, as determined by quantitative reverse transcription–polymerase chain reaction. Fold change in mRNA level shown under each bar. Error bars are standard error of the means. B: The expression of ACSL3, IFN-γ and IL-4 mRNA in peripheral blood from asthmatic patients. Fold difference in ACSL3, IFN-γ and IL-4 transcript levels from asthmatic patients compared to transcript level from healthy control as referent = 1, as determined by quantitative reverse transcription–polymerase chain reaction. Fold change in mRNA level shown under each bar. Error bars are standard error of the means.Back to article page
