Manipulating gene expression in the mature inner ear.
It is possible to manipulate gene expression in cochlear tissue, but technical issues have made this challenging in the mature in vivo inner ear. Generally, the most common reasons for such manipulations involve basic science or therapeutic quests. Examples of experimental studies are those designed to elucidate the role of a specific gene or a gene expression cascade or to understand the function of a particular cell type. Therapeutic goals may include replacing a defective gene or enhancing tissue protection, repair, or regeneration. This review summarizes the main technical approaches that are viable options for in vivo manipulation of gene expression in the mature inner ear, as well as major research and clinical issues likely to benefit from such genetic manipulations.
