In contrast, in cells transfected with miR-302a and miR-302b inhibitors, the protein and mRNA levels of IL-1β, IL-6, and TNF-α were increased (Figures 5E–H), suggesting that NF-κB was activated in control MH-S cells after PA14 infection but not in the combination of miR-302a and miR-302b mimics-transfected MH-S cells. Here, NFKB1 is linked to infection.
