Sesamin Promotes Neurite Outgrowth under Insufficient Nerve Growth Factor Condition in PC12 Cells through ERK1/2 Pathway and SIRT1 Modulation

Figure 5

Effect of sesamin enhanced NGF function on neurite outgrowth markers and synaptic connection. After cotreated with or without 1, 5, and 10 μM of sesamin and 20 ng/ml of NGF for 72 h, (a) cell lysates were collected to investigate the synaptophysin and GAP43 protein levels by western blot analysis. The β-actin was used as an internal control and band intensities were quantified by using TotalLab TL120 software. (b) The distribution of synaptophysin protein and the synaptic connection were investigated by immunostaining. (c) The bar graph showed the fluorescent intensity of synaptophysin. Data represent the means ± SD of three independent experiments. compared with the control group; and compared with the NGF alone treatment group. SE: sesamin; NGF: nerve growth factor.
