The mechanisms of the response in the murine cochlear lateral wall following sensorineural hearing loss (SNHL) are poorly understood. We focused on comparing the endocochlear potential (EP) with morphological changes in the lateral wall and expression of four important potassium (K(+)) transporters in a mouse model of SNHL induced by co-administration of aminoglycoside and loop diuretic. The expression of the ?1 and ?2 isoforms of Na,K-ATPase, Na-K-2Cl-Cotransporter-1 (NKCC1) and potassium channel KCNQ1 was assessed. The EP showed a significant decline at 12h post-treatment followed by complete recovery by 2 days post-treatment. The EP was maintained at near normal levels in animals deafened for periods up to 112 days. Despite this recovery, there was a significant and progressive decrease in the thickness of the stria vascularis, which was predominantly due to atrophy of marginal cells. Both protein and mRNA expression of ?1 and ?2 isoforms of Na,K-ATPase and NKCC1 in the lateral wall were dramatically reduced following a long-term deafening. KCNQ1 expression remained unchanged. These observations provide insight into the detailed mechanisms of EP modulation following SNHL and may have crucial implications in the future treatment of aminoglycoside-induced hearing loss.
