Immunohistochemical (IHC) detection of 15-LOX-1 (A–D) in human sinonasal tissues. Representative immunostaining for 15-LOX-1 in the UT from a control subject (A), in the UT from an ECRS subject (B), in the NP from a non-ECRS subject (C), and in the NP from an ECRS subject (D). Semiquantitative analysis of 15-LOX-1 in UT from control subjects (n = 4), in UT from patients with CRS (n = 7), in NP from patients with non-ECRS (n = 10), and in NP from patients with ECRS (n = 19) was performed (E). Magnification: ×200. *** p < 0.001, and **** p < 0.0001.
