IL17A and neoplasm: We observed that IL-17A signal in the tumor and the stromal areas significantly associated with nuclear NF-κB staining (r = 0.46, p=0.04; r = 0.53, p=0.01; Pearson) (Figure 3(c)); therefore, we concluded that IL-17A/NF-κB axis would be involved in LSCC′ epithelial to mesenchymal transition.
