OBJECTIVE This research aimed to investigate whether glutamate induced spiral ganglion neurons (SGNs) apoptosis through apoptosis inducing factor (AIF) pathway. And verify whether PD150606, a calpain inhibitor could prevent apoptosis by inhibiting cleaving and releasing AIF in mitochondrion. METHODS SGNs of postnatal days 0-3 were harvested and cultured(More)
Spiral ganglion neuron (SGN) injury is a generally accepted precursor of auditory neuropathy. Receptor-interacting protein 3 (RIP3) has been reported as an important necroptosis pathway mediator that can be blocked by necrostatin-1 (Nec-1). In our study, we sought to identify whether necroptosis participated in SGN injury. Ouabain was applied to establish(More)
The high incidence of hearing loss in human combined with the lack of hair cell regeneration in mammalian cochleae had got the attention to manipulate stem/progenitor cells to participate in hair cell regeneration for years. Cochlear progenitor cells are considered as the best candidate for hair cell regeneration. However, there is not any effective and(More)
Spiral ganglion neuron (SGN) damage and apoptosis can lead to noise-induced hearing loss, age-associated hearing loss and, in certain cases, auditory neuropathy. The apoptosis-inducing factor (AIF)-associated pathway may be important in this process. The present study aimed to investigate the expression levels of AIF and calpain in damaged SGNs.
