Impact of steroid treatment on ion homeostasis gene expression.

<p>Mice received either prednisolone (Pred) or aldosterone (Aldo) three hours after after transtympanic inoculation with <i>H flu</i> and harvested four hours later (total seven hours post inoculation). With the exception of Gja1, Aqp1, and Tmprss3, most of the genes controlling ion and fluid balances were upregulated by the steroids.
