1 Hydrogen peroxide attenuates insulin-like growth factor-1 neuroprotective effect, prevented by minocycline. Hydrogen Peroxide insulin like growth factor 1 Homo sapiens
2 We now report that sublethal doses of hydrogen peroxide attenuated IGF-1 neuroprotective activity on cultured cerebellar granule neurons under potassium and serum deprivation. Hydrogen Peroxide insulin like growth factor 1 Homo sapiens
3 Furthermore, hydrogen peroxide also blocked IGF-1"s neuroprotection for cortical neurons deprived of neurotrophic factors (B27), which was prevented by minocycline. Hydrogen Peroxide insulin like growth factor 1 Homo sapiens
4 Our data suggest that inhibition of IGF-1 signaling by hydrogen peroxide may constitute an additional pathway contributing to its neurotoxicity. Hydrogen Peroxide insulin like growth factor 1 Homo sapiens
