1 The ATM kinase inhibitor KU-55933 provides neuroprotection against hydrogen peroxide-induced cell damage via a gammaH2AX/p-p53/caspase-3-independent mechanism: Inhibition of calpain and cathepsin D. Hydrogen Peroxide ataxia telangiectasia mutated Mus musculus
2 Although KU-55933 inhibited the H2O2- and Dox-induced activation of ATM, it attenuated the toxin-induced phosphorylation of the proteins H2AX and p53 only in the latter model of cell damage. Hydrogen Peroxide ataxia telangiectasia mutated Mus musculus
3 Moreover, the ATM inhibitor prevented the H2O2-evoked increases in calpain and cathepsin D activity and attenuated cell damage to a similar degree as inhibitors of calpain (MDL28170) and cathepsin D (pepstatin A). Hydrogen Peroxide ataxia telangiectasia mutated Mus musculus
