What are significant findings on DFNB9 mice models?
DFNB9 mice models have shown significant findings related to the restoration of otoferlin expression and the reversal of the deafness phenotype through gene therapy using adeno-associated virus (AAV) vectors . Another study on DFNB9 mice models revealed that the lack of calcium-binding proteins (Cabp1 and Cabp2) led to impaired synaptic transmission and elevated auditory brainstem response (ABR) thresholds, but AAV-mediated Cabp2 expression partially restored calcium channel function and improved ABR thresholds . Additionally, the study found that reduced signaling of brain-derived neurotrophic factor (BDNF) receptor TrkB aggravated memory impairment in DFNB9 mice models, and BDNF protein levels were reduced in the cortex of these mice . Furthermore, DFNB91 mice models lacking the Serpinb6a gene exhibited progressive hearing loss, which was delayed when transferred onto a Cdh23 normal background, suggesting that Serpinb6 helps maintain hearing by protecting hair cells from stress . Lastly, Coch(G88E/G88E) mice models for DFNA9 showed elevated vestibular-evoked potential (VsEP) thresholds and progressive hearing loss, providing an opportunity to study age-related hearing loss and potential therapies .

The provided paper is about a Coch(G88E/G88E) mouse model for DFNA9 late-onset hearing loss and vestibular dysfunction. The significant findings on the DFNA9 mice models include elevated vestibular-evoked potential (VsEP) thresholds, substantially elevated auditory brainstem response (ABR) thresholds at 21 months, and lower distortion product otoacoustic emission (DPOAE) amplitudes. | |
3 Citations | The paper discusses the use of a mouse model to study DFNB91, a form of progressive hearing loss in humans. The study shows that mice lacking the Serpinb6a gene exhibit early-onset hearing loss, which can be delayed by transferring the mutant allele onto a different mouse strain. The mice also show increased susceptibility to permanent hearing loss after exposure to acoustic trauma. |
52 Citations | The provided paper is about the impact of Bdnf gene deficiency on memory impairment and brain pathology in a mouse model of Alzheimer's disease. There is no mention of DFNB9 mice models in the paper. |
The significant findings on DFNB9 mice models include the restoration of otoferlin expression and the reversal of the deafness phenotype through a dual AAV-mediated gene therapy approach. | |
The provided paper is about a mouse model for DFNB93, not DFNB9. Therefore, there is no information about significant findings on DFNB9 mice models in the paper. |
