Effect of noise exposure on the protein level of Cx30 in the SL.

<p>Animals were exposed to noise at 110(<b>a</b>) Tissue lysates were prepared from the SL of the cochlea on day 7 post-noise exposure as well as from that of naïve animals for determination of Cx30 levels by immunoblot analysis. Values are the means ± S.E. from 4 separate animals per each group. *<i>P</i><0.05, significantly different from control value obtained for naïve animals. (<b>b</b>) At the various time points indicated post-exposure, animals were fixed for preparation of cochlear slices, which were then immunostained for Cx30 in the lateral wall structures of the cochlea. These experiments were carried out at least 6 times under the same experimental conditions, with similar results.
