Role of somatostatin receptor-2 in gentamicin-induced auditory hair cell loss in the Mammalian inner ear.
... Interestingly, we found that octreotide significantly reduced HC loss in OC samples treated with gentamicin, as compared to in samples treated with gentamicin alone. Moreover, western blotting revealed that octreotide ...

HCN channels are not required for mechanotransduction in sensory hair cells of the mouse inner ear.
... We detected no immunoreactivity for HCN2 or HCN4 in either auditory or vestibular hair cells, though both were detected in the afferent neurons that innervate inner ear organs (not shown). The Figure 1. ...

Tinnitus and other auditory problems - occupational noise exposure below risk limits may cause inner ear dysfunction.
... Very few subjects with fully developed hyper-PMTFs (P- type = 3), suggesting exposure to impulse noise possibly associated to damage in the inner hair cell area [4,16,22], were found in this study. Although the ...
