Injection of AAV-shCtrl and AAV-shCaMKKβ to p1–2 FVB/NJ mice does not influence hearing and outer hair cell function. A Auditory baseline thresholds show no significant difference among the three groups (control mice without injection and AAV-shCtrl- and AAV-shCaMKKβ-injected mice) at all tested frequencies (8, 16, and 32 kHz) measured after mice were weaned at postnatal day 21. Data are presented as individual points with means ± SD, ns: not significant. B DPOAE amplitudes show similar waveforms from 4 to 36 kHz among the above three groups. Data are presented as means ± SD, n = 6–7 in each group
