Article Abstract
The aim of this study was to investigate the effects of actin depolymerizing factor (ADF)/destrin and position changes of kinetosomes in the development of hair cells following Atoh1-induced ectopic regeneration in the basilar membrane of mice. We observed through immunofluorescence at various time-points the expression of ADF/destrin and the specific kinetosome marker, γ-tubulin, in hair cells following ectopic regeneration induced by adenovirus transfection, overexpression of Atoh1 and culture. Changes of ADF/destrin distribution and kinetosome position during culture of new hair cells [Myo7a(+)] following Atoh1-induced ectopic regeneration are consistent with the changes in ADF/destrin expression and the polar migration of kinetosomes in hair cells of the cochlear sensory epithelium in normal development. ADF/destrin is involved in the development of the auditory epithelium and the development and structural rearrangement of ectopically regenerated hair cells in mammals. The kinetosomes of hair cells following Atoh1-induced ectopic regeneration show positional changes at different time-points.

Gadolinium-based contrast agents (GBCAs) are widely used in systemic magnetic resonance imaging (MRI) and can be employed in otology to evaluate endolymphatic hydrops in patients with Ménière's disease. Given the heavy metal properties of gadolinium and its tendency to deposit in tissues, it is essential to assess its ototoxic risk. We evaluated the ototoxicity of gadodiamide using in vitro and in vivo models.

Morphogenetic information arises from a combination of genetically encoded cellular properties and emergent cellular behaviors. The spatio-temporal implementation of this information is critical to ensure robust, reproducible tissue shapes, yet the principles underlying its organization remain unknown. We investigated this principle using the mouse auditory epithelium, the organ of Corti (OC).

Background: Persistent chemotherapy-induced alopecia (pCIA) is a distressing side effect of antineoplastic agents, imposing significant psychological burdens on cancer survivors. Despite its impact, there are no standardized guidelines for diagnosis, prevention or management.
Objective: To establish consensus-based definitions, diagnostic criteria, grading systems and management recommendations for pCIA.

Purpose: Delivery of therapeutics to the inner ear is complicated by their inaccessible location and the presence of the blood-labyrinth barrier that restricts most blood-borne compounds from entering the inner ear. This study addresses the challenge of optimal delivery in treating inner ear disease, focusing on magnetic targeting gene therapy using adeno-associated virus (AAV).
Methods: The investigation explores three AAV serotypes (AAV2 Quad Mut, AAV2 pANC80L65, and AAV9 PHP.
