AMø of current smokers show no reduction in mRNA expression of cytoplasmic dsRNA receptors, relative to AMø of never-smokers. RNA from AMø was isolated, depleted of contaminating genomic DNA, reverse-transcribed and analyzed by quantitative real-time RT-PCR using Taqman chemistry and specific primer-probe sets, normalized to GAPDH transcripts. Data are expressed on the horizontal axis as mean ± SEM for relative quantity (dRn), calculated in comparison to a single never-smoker who was arbitrarily designated the reference sample. Never-smokers (n = 6), red bars; smokers (n = 11), blue bars. The Mann–Whitney test was used to calculate statistical significance.
