FIGURE 1.

ROR1, Wnt5a and NF‐κB p65 positive expression is at a low level in the outer hair cells of cochlear tissues of the NIHL guinea pig models. Guinea pigs with NIHL were treated with ROR1 vector or empty vector. (A) the immunohistochemical staining of ROR1, Wnt5a and NF‐κB p65 in the outer hair cells of cochlear tissues (scale bar = 25 μm); (B) the statistical analysis of panel A. The data are presented as a mean ± standard deviation. One‐way ANOVA is performed for multiple‐group comparison. ^* P < 0.05 vs. the normal group; ^# P < 0.05 vs. the empty vector group. n = 15
