Fig 6. Effect of antioxidant enzyme-inducing sulforaphane on production of IL-6, CXCL8 and GM-CSF by NIST-stimulation HBECs.

Cytokines produced by primary HBECs in submerged cultures for 24 hours stimulated with NIST at 50μg/ml and/or sulforaphane at 3μM. Friedman’s tests with Dunn’s multiple comparisons tests; n = 4. Statistical significance as follows: **, p ≤ 0.01.
