Figure 3: γ-H2Ax levels within the organ of Corti. γ-H2Ax levels were quantified in mathematical energy units per pixel (Em /pix) and displayed in panels A-B as a function of the treatment conditions. Note that there were no significant differences in γ-H2Ax level between the control and CAE conditions. However, there was a marked increase after noise or co-treatment with CAE and noise. The level of γ-H2Ax is significantly lower in the CAE+noise condition relative to the noise-only condition. This effect is further supported in Panel B where γ-H2Ax levels for individual cochlear turns were quantified. Errors bars are standard errors of the means.
