Figure 3. Oc90 (A, C) and otolin (B, D) expression levels in murine inner ear.

Figure 3

Quantitative real-time RT-PCR (qRT-PCR) showed that both Oc90 and otolin had significantly higher expression levels in the utricle and saccule than the ampulla, canal or cochlea in wt mice. The mRNA levels were normalized to that of β-actin (relative mRNA level), and then different tissues were compared to the utricle and saccule whose relative mRNA level was set to 1 (A, B). In (C, D), the relative mRNA level in the E17.5 cochlea was set to 1. The vestibular samples in C and D mainly consisted of the utricle+saccule with a small part of the ampulla. ** and *** denote p<0.01 and 0.001, respectively, when the utricle+saccule are compared with other tissues (n = 3 for each type of tissue in each age group). ### and $$$ denote p<0.001 when P7 is compared with E17.5 and P0, respectively.
