Studies of intercellular Ca2+ signaling and gap-junction coupling in the developing cochlea of mouse models affected by congenital hearing loss [PDF]
Connexin 26 (Cx26) and connexin 30 (Cx30) form gap junction channels that allow the intercellular diffusion of the Ca2+ mobilizing second messenger IP3.

Our mouse model with a c.259G>A transition in PRPS1 showed a significant decrease in the number of hair cells and SGN counts at 48 weeks of age and a reduction in Prps1 enzymatic activity in the KI mouse. This model will serve as a valuable tool for developing therapeutic strategies.

Implication of GPRASP2 in the Proliferation and Hair Cell‐Forming of Cochlear Supporting Cells
Schematic diagram of GPRASP2‐mediated SCs proliferation and HCs formation. GPRASP2 deficiency results in increased lysosomal degradation of SMO. GPRASP2‐mediated SMO/GLI1 signalling promotes SC proliferation, which contributes to HC formation. GPRASP2‐mediated SMO/β‐catenin signalling is implicated in HCs fate specification and differentiation ...

Neomycin induces increased expression of Xaf1 in cochlear HCs, triggering PANoptosis, which encompasses pyroptosis, apoptosis and necroptosis (left). Targeted Xaf1 knockdown in HCs through gene therapy can significantly inhibit the occurrence of PANoptosis in HCs (right).

Inner ear formation requires that a series of cell fate decisions and morphogenetic events occur in a precise temporal and spatial pattern. Previous studies have shown that transcription factors, including Pax2, Sox2, and Prox1, play important roles ...

Piezo2 in Mechanosensory Biology: From Physiological Homeostasis to Disease‐Promoting Mechanisms
Piezo2 channels are essential mechanotransducers regulating touch, proprioception and visceral mechanosensation across physiological systems, emerging as therapeutic targets for pathological mechanical hypersensitivity and neurogenic disorders. ABSTRACT Piezo2, a mechanically activated ion channel, serves as the key molecular transducer for touch ...

Gasdermins: multifunctional effectors of membrane permeabilization across cellular compartments
Gasdermins (GSDMs) are pore‐forming proteins best known for driving pyroptosis through plasma membrane (PM) permeabilization. Beyond triggering inflammatory cell death, GSDMs can also associate with organelle membranes, including mitochondria, lysosomes, ER, and nucleus, where they modulate membrane integrity and cellular signaling.

Semicircular canal morphology in Rodentia and its relationship to locomotion
Here, we present a selection of rodent inner ear 3D models in the lateral view, with rodents from seven locomotor categories (left to right: fossorial, semifossorial, semiaquatic, terrestrial, ricochetal, arboreal, and gliding). Semicircular canal (SCC) morphology, including radius of curvature and shape, can be differentiated between specialized forms
