We next examined the effect of IL-17A on cell proliferation using the highly sensitive cell proliferation detection kit, CCK-8, and observed that proliferation rates of all IL-17A-overexpressing NSCLC cells increased compared to control cells after 24 (Figure 2C, left panel) and 48 h (Figure 2C, right panel) of incubation. Here, IL17A is linked to non-small cell lung carcinoma.
