With regard to lung cancer, IL-17 has been reported to induce IL-6 expression13 in A549 cells, and Numasaki M et al. 7 have demonstrated that IL-17 increases IL-6 and IL-8 expression in A549, Sq-19 and LK-87 cells but that VEGF production is not altered in these three cell lines using ELISA. The gene discussed is CXCL8; the disease is lung cancer.
