    ..These data demonstrated that the Gen-Panx1 KO mouse has hearing loss and further confirmed that Panx1 deficiency can cause deafness. ..

    ..These data suggest that Cx26 deficiency may impair active cochlear amplification leading to late-onset hearing loss. Our study also helps develop newer protective and therapeutic interventions to this common nonsyndromic hearing loss. ..
  4. Zhao H, Zhu Y, Liang C, Chen J. Pannexin 1 deficiency can induce hearing loss. Biochem Biophys Res Commun. 2015;463:143-7 pubmed publisher
    ..These data indicate that like connexins Panx1 deficiency can also induce hearing loss. These data also suggest that pannexins play important rather than redundant roles in the cochlea and hearing. ..
  5. Chen J, Chen J, Zhu Y, Liang C, Zhao H. Deafness induced by Connexin 26 (GJB2) deficiency is not determined by endocochlear potential (EP) reduction but is associated with cochlear developmental disorders. Biochem Biophys Res Commun. 2014;448:28-32 pubmed publisher
    ..These data suggest that congenital deafness induced by Cx26 deficiency is not determined by EP reduction and may result from cochlear developmental disorders. ..

    ..However, detailed information about pannexin function in the cochlea and Panx mutation induced hearing loss still remain largely undetermined. Further studies are required. ..

    ..This further supports our previous reports that Cx26 and Cx30 can solely and concertedly perform different functions in the cochlea...

    ..These new data also suggest that cochlear gap junctions may have an important role in age-related hearing loss. ..

Neurobiol Dis. 2017;108:195-203 pubmed publisher
    ..These data further suggest that digenic Cx26 and Cx30 mutations may impair heterozygous coupling of Cx26 and Cx30 in the cochlear lateral wall to reduce EP, thereby leading to hearing loss. ..
