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

Figure 3

Dose-dependent effect of sesamin on morphological differentiation and neurite length by NGF stimulation. The PC12 cells enhanced the differentiation with NGF at 20 ng/ml and cotreated with/or without sesamin at various concentrations (1, 5, and 10 μM) for 72 h. (a) The morphological change was observed under an inverted phase-contrast microscope. (b) The bar graph showed the calculation of differentiation percentage. (c) Neurite length was quantified by AxioVision Rel.4.8. 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.
