Expression of prestin in rats during cochlear development. (a) Representative prestin and GAPDH immunobands from western blots were detected at 81 kD and 36 kD. GAPDH was used as the internal control. (b) Relative expression of prestin (all normalized to GAPDH) at different postnatal ages. Comparisons are shown by the bars above the relevant columns. Data were obtained from four independent experiments and are expressed as mean ± SD. ^∗ p < 0.05; ^∗∗ p < 0.01; ^NS p > 0.05 (Student's t-test).
