Figure 4.IL-17a expression is up-regulated in patients with lung cancer. (A) Images showing IL-17a expression levels in tumor samples from patients with lung cancer using IHC. Scale bar, 100 μm. (B) IL-17a expression levels in the primary lung tumor specimens and the adjacent normal tissue samples by RT-qPCR (n = 48). (C) Western blot analysis of IL-17a expression levels in the primary lung tumor specimens and the paired lung alveolar tissue samples (n = 8). (D) Kaplan-Meier survival curves for overall survival (OS) in lung cancer patients according to the expression levels of IL-17a. All data are expressed as mean ± SEM. ^**p<0.01.
