miR-708 Negatively Regulates TNFα/IL-1β Signaling by Suppressing NF-κB and Arachidonic Acid Pathways

Figure 2

miR-708 and AA signaling regulation is uncoupled in TNFα/IL-1β-modulated diseased lung cells. (a) Representative western blot of COX-2 and mPGES-1 protein expression from 0 to 48 hours after TNFα/IL-1β exposure in A549 cells. GAPDH served as a loading control. (b) RT-qPCR of mature miR-708 in Beas2b (blue, nondiseased) and A549 (red, diseased) cells 0–48 hours post-TNFα/IL-1β exposure. miR-708 expression was normalized to U6 snRNA and analyzed using the 2-ΔΔCT method. and , .
