NE affects auditory function and elevates expression of MMP-associated genes in the stria vascularis. (A) ABR thresholds to tone bursts in the control and NE groups. (B) 15 MMP genes were constitutively expressed in healthy stria vascularis. (C) Noise exposure caused dynamic; however, not significant alterations in the expression level of MMP-associated genes in the stria vascularis. The vertical axis is scaled logarithmically. NE, noise exposure; ABR, auditory brainstem response; MMP, matrix metalloproteinase.
