title: Update: Data on the responses of neurons and astrocytes to oxidative injury in the presence of insulin-like growth factor I

description: Fig1a) Neuron viability measured as percentage of GFP positive cells cultured ± astrocytes after treatment with H2O2. N: neurons, NA: neurons + astrocytes. Names for each file refer to the related figures in the associated research article. Fig1b) IGF-I measured in the supernatant of neuron or astrocyte cultures treated ± with H2O2. Fig1c) UPDATED with additional data: pAKT levels measured in astrocytes transfected with an IGF-IR dominant negative construct (IGF-IR DN) after treatment with IGF-I. Fig1d) Neuron viability measured as percentage of GFP positive cells cultured with astrocytes transfected with IGF-IR DN. Fig2a) pAKT levels in astrocytes treated ± with PPP (picropodophyllin) after treatment with IGF-I. Fig2b) Neuron viability measured as percentage of GFP positive cells treated ± with PPP and H2O2. Fig2c) Neuron viability expressed as percentage of GFP positive cells cultured with astrocytes and treated ± with PPP and H2O2. Fig2d) Neuron viability measured as percentage of GFP positive cells cultured with astrocytes (both cells types from forebrain) and treated ± with PPP and H2O2. Fig2e) Neuron viability measured as percentage of GFP positive cells cultured with astrocytes and treated with IGF-I, H2O2 or both.
