Figure 4.

Overexpression of miR-18a-5p promoted cell apoptosis and inflammation in 16HBE cells. (a) miR-mimic transfection significantly elevated the cell miR-18a-5p levels, while miR-18a-5p inhibitor transfection showed the opposite effect. (b) and (c) Overexpression of miR-18a-5p significantly inhibited cell viability and promoted cell apoptosis. MiR-18a-5p downregulation promoted cell viability and inhibit cell apoptosis, but the differences were not significant. (d) The levels of IL-6, IL-8, IL-1β, and TNF-α were all increased significantly by miR-18a-5p mimic transfection.
