Fig 4. Concentration dependent effects of miR-146a on cytokine repression in airway epithelial cells.

A549s were transfected with miR-146a mimic or negative control small RNA, stimulated with TNF-α, and then dexamethasone was added at increasing doses. CCL2 and IL-6 levels were measured by qRT-PCR. Results are shown as the mean ± SEM, n = 3.
