The mitochondrially-targeted antioxidant mitoTEMPO protects against acute neomycin damage from neomycin but not delayed damage from G418. 50 μM mitoTEMPO was added for 30 min before AG (purple bar), co-treated with neomycin for 1 h or co-treated with G418 for 1 h (red bar), rinsed, and incubated with mitoTEMPO alone for 23 h (purple bar).
