Aβ₄₂ increased immunoreactivity of p-cPLA₂ in a time-dependent manner. DITNC cells were stimulated with Aβ₄₂ (1 µM) for different incubation times and were subjected to Western blot analysis with anti-p-cPLA2 and anti-cPLA₂ antibody. Results were from one representative experiment (upper). Repeated experiments gave similar results. For each sample, the relative intensity of phosphorylated cPLA₂ was normalized by the total cPLA₂ (lower). Values are the mean of three independent experiments. (*p < 0.02)
