Differential expression of primary transcripts of selected LPS-up-regulated mature miRNAs in H69 cells. H69 cells were exposed to LPS for 2–12 h and primary transcripts (pri-miRNAs) of select miRNAs were quantified by real-time PCR. The amount of pri-miRNAs was obtained by normalizing to the level of GAPDH in the samples. Data are expressed as the amount of pri-miRNAs in LPS-stimulated samples relative to the control non-stimulated samples and representative of three independent experiments. *P < 0.05 t-test versus the non-stimulated cells.
