Total RNA was treated with DNase and then reverse transcribed into first-strand cDNA in a 20-mL reaction volume employing SuperScript III Reverse Transcriptase (Invitrogen, CA, USA). Quantitative real-time reverse transcription (RT)-PCR assays of Kcnj10 cDNA have been performed using a gene-specific double fluorescently labeled TaqMan probe in an ABI Prism 7900 Sequence Detection Technique (Applied Biosystems) in accordance with the manufacturer’s suggestions. The relative mRNA expression level was determined by the 22DDCt analysis technique, and calculations had been performed utilizing the software provided by the manufacturer (Applied Biosystems). Specimens from 5 mice have been collected for each experiment, and the experiments have been performed in triplicates and averaged. The average mRNA expression level in wild-type mice was normalized to 1 because the manage.UK) by semi-dry electroblotting. The PVDF membranes were created with an enhanced chemiluminescence western blot detection kit (Pierce SuperSignalH West Dura, Rockford, IL, USA) and exposed to Lumi-Film chemiluminescent detection films (Roche Diagnostics, Mannheim, Germany).Trifluridine The specimens had been collected from five mice for each and every experiment, as well as the experiments were performed in triplicates and averaged. The average protein expression level in wild-type mice was normalized to 1 because the manage.Noise Exposure ExperimentsFor the noise exposure experiments, ten mice of every single genotype had been exposed for 3 h to octave-band noise having a peak at 4 kHz, 115 dB SPL. The noise room was fitted using a speaker (model NO. 1700002, GSI) driven by a noise generator (GSI-61; Grason-Stadler, Inc.) and also a power amplifier (5507-Power; TECHRON). ABR thresholds (dB SPL) in mice at unique frequencies (click, 8 kHz, 16 kHz, and 32 kHz) were then recorded at 30 min and at day 1, 2, 3, 7, and 14 immediately after noise exposure.Western Blot AnalysisProtein extracts from the inner ear were homogenized in RIPA buffer (Millipore, MO, USA). Equal amounts of proteins were supplemented with dithiothreitol, heated for 5 min at 95uC, separated by SDS gel electrophoresis, then transferred to a PVDF membrane (Amersham Pharmacia Biotech, Small Chalfont,Thyroid and Renal Serum BiochemistryTerminal blood samples were obtained from mice at postnatal day 15 to evaluate the early postnatal T4 surge [26], as well as at two and 6 months of age to monitor the long-term thyroid and renalPLOS A single | www.plosone.orgMouse Model with SLC26A4 p.H723R MutationTable 1.Lysostaphin Comparison of phenotypes amongst mouse strains segregating distinct Slc26a4 mutations.PMID:23775868 Slc26a4tm2Dontuh/ Slc26a42/Audiological phenotypes Profound hearing loss (.100 dB SPL)Slc26a4loop/loopProfound hearing loss (.100 dB SPL)Slc26a4tm1Dontuh/tm1DontuhProfound hearing loss (.120 dB SPL)Tg[E];Tg[R];Slc26a4D/D Hearing levels rely on the time of Slc26a4 expression.
