Electroporation-mediated gene transfer to the developing mouse inner ear.
The mammalian inner ear forms from a thickened patch of head ectoderm called the otic placode. The placodal ectoderm invaginates to form a cup whose edges cinch together to establish a fluid-filled sac called the otic vesicle or otocyst. The progenitor cells lining the otocyst lumen will give rise to sensory and non-sensory cells of the inner ear. These formative stages of inner ear development...
متن کاملMouse model of enlarged vestibular aqueducts defines temporal requirement of Slc26a4 expression for hearing acquisition.
Mutations in human SLC26A4 are a common cause of hearing loss associated with enlarged vestibular aqueducts (EVA). SLC26A4 encodes pendrin, an anion-base exchanger expressed in inner ear epithelial cells that secretes HCO3- into endolymph. Studies of Slc26a4-null mice indicate that pendrin is essential for inner ear development, but have not revealed whether pendrin is specifically necessary fo...
متن کاملLocal gene therapy durably restores vestibular function in a mouse model of Usher syndrome type 1G.
Our understanding of the mechanisms underlying inherited forms of inner ear deficits has considerably improved during the past 20 y, but we are still far from curative treatments. We investigated gene replacement as a strategy for restoring inner ear functions in a mouse model of Usher syndrome type 1G, characterized by congenital profound deafness and balance disorders. These mice lack the sca...
متن کاملHave You Heard? Viral-Mediated Gene Therapy Restores Hearing
Genetic loss of VGLUT3 in cochlear inner hair cells results in profound deafness. In this issue of Neuron, Akil et al. (2012) show that AAV-mediated introduction of wild-type VGLUT3 in the genetically deaf mouse cochlea results in significantly improved hearing.
متن کاملEstablishment of a Knock-In Mouse Model with the SLC26A4 c.919-2A>G Mutation and Characterization of Its Pathology
Recessive mutations in the SLC26A4 gene are a common cause of hereditary hearing impairment worldwide. Previous studies have demonstrated that different SLC26A4 mutations may have different pathogenetic mechanisms. In the present study, we established a knock-in mouse model (i.e., Slc26a4(tm1Dontuh/tm1Dontuh) mice) homozygous for the c.919-2A>G mutation, which is a common mutation in East Asian...
