Figure 5.
Effect of NGF or NGF(1-14) peptides on TrkA phosphorylation. Representative western blotting (A,B) and densitometric analyses (C) of pTrkA in PC12 cells treated with 50 μM NGF peptides in the absence (☐) or in the presence of 1 μM CuSO4 (■) or 50 μM BCS 24 h pre-treated medium (■) for 10 min. Data obtained from at least three independent experiments. The phosphorylated level of TrkA was reported as the ratio over the corresponding total protein (* p < 0.05, *** p < 0.001 versus control; §§§ p < 0.001 versus CuSO4; ### p < 0.001 versus BCS; one-way Anova).
