Tsukushi is essential for the development of the inner ear

Molecular Brain, 2020
Tsukushi (TSK)—a small, secreted, leucine-rich-repeat proteoglycan—interacts with and regulates essential cellular signaling cascades. However, its functions in the mouse inner ear are unknown.

Beyond mammals: the evolution of chewing and other forms of oropharyngeal food processing in vertebrates

Biological Reviews, EarlyView.
ABSTRACT Oropharyngeal food processing exhibits a remarkable diversity among vertebrates, reflecting the evolution of specialised ‘processing centres’ associated with the mandibular, hyoid, and branchial arches. Although studies have detailed various food‐processing strategies and mechanisms across vertebrates, a coherent and comprehensive terminology ...

Navigating the Genetic Risk of Chemotherapy‐Induced Hearing Loss in the Stria Vascularis

Clinical Pharmacology &Therapeutics, EarlyView.
Cisplatin is a chemotherapy drug that causes permanent hearing loss by damaging a critical tissue lining the inner ear, called the stria vascularis (SV). Currently, the molecular mechanisms of SV damage are largely unknown and the incidence of ototoxicity in patients cannot be reliably predicted.

The segregation of Calb1, Calb2, and Prph neurons reveals distinct and mixed neuronal populations and projections to hair cells in the inner ear and central nuclei

Developmental Dynamics, EarlyView.
Three populations of hair cells have a distinct expression of Calb1 and Calb2. (A, A′D) The central is highly positive for Calb1 while surrounding HC are positive for Calb2. Later, a calyx forms primarily with Calb1. (B, B′, D′, D″) Saccule and utricle start out positive for Calb2 but will upregulate the Calb1 in the striola that is primarily forming ...

Correct Timing of Proliferation and Differentiation is Necessary for Normal Inner Ear Development and Auditory Hair Cell Viability [PDF]

Developmental Dynamics, 2013
Background: Hearing restoration through hair cell regeneration will require revealing the dynamic interactions between proliferation and differentiation during development to avoid the limited viability of regenerated hair cells. Pax2‐Cre N‐Myc conditional knockout (CKO) mice highlighted the need of N‐Myc for proper neurosensory development and ...

NAD+ Enhanced on Hearing Recovery in Sudden Sensorineural Hearing Loss: Randomized Controlled Trial

The Laryngoscope, EarlyView.
This 2‐year, single‐center, double‐blind study with a small sample size compared NAD+ and control groups in a randomized controlled trial for sudden sensorineural hearing loss (SSNHL). Results showed that NAD+ led to better hearing improvement from 7 days to 3 months and a shorter average recovery time compared to the control group.

Mesna in Otologic Surgery: Efficacy and Safety—A Scoping Review

The Laryngoscope, EarlyView.
PRISMA flow diagram indicating the process of systematic inclusion and exclusion of articles. ABSTRACT Objective Mesna (Sodium 2‐mercaptoethanesulfonate) is widely used as a mucolytic agent and uroprotective agent. Recently, its disulfide bond‐breaking property has been applied in otologic surgery to facilitate safer dissection of cholesteatoma and ...

Inner Hair Cell Loss Disrupts Hearing and Cochlear Function Leading to Sensory Deprivation and Enhanced Central Auditory Gain [PDF]

Frontiers in Neuroscience, 2017
There are three times as many outer hair cells (OHC) as inner hair cells (IHC), yet IHC transmit virtually all acoustic information to the brain as they synapse with 90-95% of type I auditory nerve fibers. Here we review a comprehensive series of experiments aimed at determining how loss of the IHC/type I system affects hearing by selectively ...

Pathogenesis of Age‐Related Hearing Loss and Therapeutic Strategies

Sensory Neuroscience, EarlyView.
ABSTRACT Age‐related hearing loss (ARHL) is a degenerative disorder of the auditory system, characterized by bilateral symmetrical sensorineural hearing loss that occurs with aging. As a highly prevalent age‐related condition worldwide, ARHL significantly impairs both the quality of life and mental health of the elderly.

Concurrent Maturation of Inner Hair Cell Synaptic Ca2+ Influx and Auditory Nerve Spontaneous Activity around Hearing Onset in Mice [PDF]

Journal of Neuroscience, 2013
Hearing over a wide range of sound intensities is thought to require complementary coding by functionally diverse spiral ganglion neurons (SGNs), each changing activity only over a subrange. The foundations of SGN diversity are not well understood but likely include differences among their inputs: the presynaptic active zones (AZs) of inner hair cells (
