Sensorineural hearing loss is the most common type of hearing loss. It is most often caused by defects in cochlear hair cells, the primary sensors for sound that convert mechanical sound stimuli into electrical signals that are transmitted to the nervous system. Approximately 135 genetic loci have been linked to hearing loss, and about 60 affected genes have been identified. However, the physiological functions of these genes are not well-studied. The Laboratory of Molecular Mechanisms of Auditory Perception and Deafness is finding the ability to illustrate the functions of these genes – and discover new ones – that could provide fresh leads for developing novel treatments for some forms of hearing loss.
Bo Zhao, PhD, recently collected cochlear cell tissue to construct libraries for yeast two-hybrid screening and examine interactions between proteins. In previous studies, Zhao has successfully used these libraries to illustrate the functions of two deafness proteins linked to hearing loss. Continued work aims to reveal the functions of other deafness-related genes and uncover other genes linked to hearing loss. The Laboratory of Molecular Mechanisms of Auditory Perception and Deafness is a part of the Department of Otolaryngology – Head and Neck Surgery.
