Figure Lengend Snippet: A: Animal genotype and experimental timeline. B: Evaluation of auditory brainstem response between genotypes. There was a significant main effect of control vs. cKO (F (1, 3) = 20.21, p = 0.0205, peta2 [95%CI] = 0.87 [0.05 – 0.96]). Multiple comparison showed Adjusted p value =0.0045 at 8KHz, adjusted p value = 0.0045 at 16 KHz and, adjusted p value =0.0146 at 32 KHz (N=3; N=2). C: Graph of the endocochlear potential recorded between genotypes. To assess statistical significance between control and conditional knockout, Student’s t -tests were conducted to calculate p values. Pax3CreER-Kir4.1 fl/+ vs. Pax3CreER-Kir4.1 fl/fl , p value = 0.0034 (N=4; N=2). Immunostaining for evaluation of Kir 4.1 expression in the inner ear of WT (D) and conditional knockout (cKO) (E). Bracket for organ of Corti, arrows for Kir 4.1 positive melanocytes, stars for Kir 4.1 negative cells in the intermediate cell layer of the stria vascularis. RM: Reissner’s membrane, SGN: spiral ganglion neurons, TAM: Tamoxifen induction.
Article Snippet: The slides were washed with 1x PBS and immunolabelled the intermediate cells with primary antibody CD44 (Rat MA4405, Fisher Scientific, 1:250) or KIR 4.1 (Rabbit APC-035, Alomone; 1:100) diluted in 5% serum/PBS overnight at 4°C.
