(A) Western blots of E-cadherin and β-actin obtained from control explant cultured for 24 h (0 PQ, 24 h) and explants treated with 200 μM PQ and cultured for 6, 12 or 24 h. (B) Mean (SEM, n=3 replicates/condition, 6 or more cochlear/measurement) values of E-cadherin relative to β-actin in controls explants (0 PQ, 24 h) and explants treated with 200 μM PQ for 6, 12 or 24 h. (C) Western blots of β-catenin and β-actin obtained from control explants cultured for 24 h (0 PQ, 24 h) and explants treated with 200 μM PQ and cultured for 6, 12 or 24 h. (D) Mean (SEM, n=3 replicates/condition; 6 or more cochlea/measurement) values of β-catenin relative to β-actin in controls explants (0 PQ, 24 h) and explants treated with 200 μM PQ for 6, 12 or 24 h. Horizontal bars identify PQ treatment durations that were significantly different from controls (p<0.05).
