Fig. 4From: Sex differences in hearing impairment due to diet-induced obesity in CBA/Ca miceDensity of HC ribbon synapses (CtBP2) are sexually dimorphic. a–f Confocal images of CtBP2 (red) puncta in the IHC synapses of female (a–c) and male (d–f) mice (30 kHz region). g The number of pre-synaptic ribbon synapses were examined from whole-mount cochleae. Quantified analysis confirmed that sex differences in the expression of CtBP2 puncta were found in the inner hair cells and synapses. Two-way ANOVA; Tukey's multiple comparisons test; *p < 0.05.
