New discovery from scientists: Hearing loss in mice cured

The scientists said they had successfully reversed hearing loss in mice, suggesting that some forms of deafness caused by faulty genetic activity could be prevented and also completely reversed in humans.

Hearing loss in humans can also be resolved

According to a new study published in the Proceedings of the National Academy of Sciences, researchers were able to restore the low and mid-frequency ranges of hearing in some mice to near-normal levels. “Degenerative diseases such as progressive hearing loss are generally believed to be irreversible, but we have shown that at least one type of inner ear dysfunction can be reversed,” said study author Karen Steel, professor of sensory function at King’s College London. he said in a statement.

The researchers made their breakthrough by focusing on a gene called Spns2. In the study, mice bred with defective Spns2 genes showed rapid worsening of hearing loss. The researchers reactivated these useless genes in mice of different ages using a special enzyme, and then evaluated the rodents’ hearing using what’s known as the auditory brainstem response test. They found that in young mice, hearing loss was almost completely reversed when the gene was activated. However, the older a mouse was when it received the treatment, the less hearing it gained. At the end of the experiment, it became clear that the best results for the treatment should be applied as young as possible. Researchers hope that they can also use this experiment to solve hearing loss in humans.
