    Oregon Hearing Research Center, Oregon Health and Science University, Portland, Oregon 97239, USA
    Toxicol Sci 124:378-87. 2011
    ..Therefore, we conclude that CRT binding to gentamicin is protective against gentamicin-induced cytotoxicity...

    Cell Death Dis 1:e102. 2010
    ..Gentamicin also enhanced the binding between CLIMP-63 and 14-3-3 proteins, and we also identified that 14-3-3 proteins are involved in gentamicin-induced cytotoxicity, likely by binding to CLIMP-63...

    Integr Biol (Camb) 3:879-86. 2011
    ..We also discuss potential strategies to reduce aminoglycoside cytotoxicity, which are necessary for greater bactericidal efficacy during aminoglycoside pharmacotherapy...

    Takatoshi Karasawa
    Oregon Hearing Research Center, Oregon Health and Science University, 3181 Sam Jackson Park Road, Portland, OR 97239, USA
    J Cell Sci 121:2871-9. 2008
    ..In an endolymph-like extracellular environment, clearance of GTTR was attenuated from KPT2-TRPV4 cells in a TRPV4-dependent fashion. We propose that TRPV4 has a role in aminoglycoside uptake and retention in the cochlea...

    ..Finally, we will conduct in vivo gentamicin injection experiments and determine if strial endothelial cells uptake gentamicin, allowing the drug to pass through stria vascularis, and if this process is also dependent on TRPV4 channel. ..
