MicroRNAs (miRs) are small non-coding single-stranded RNAs that bind to their complimentary sequences in the 3'-untranslated regions (3'-UTRs) of the target mRNAs that prevent their translation into the corresponding proteins. Since miRs are strongly expressed in cells of inner ear and play a role in regulating their differentiation, survival and function, alterations in their expression may be...

Chronic tinnitus can often be temporally associated with a loss of sensorineural hearing. However, also occur in people normal hearing and thus arise without traceable disorder the inner ear. In present study, we tested whether fine-structure audiometry or high-resolution measurement otoacoustic emissions reveal evidence inner-ear-related disorders that remain undetected by conventional manual ...
