Abstract:
This study evaluates the proliferative and migrative effects of dangshen on RSC96, Schwann cells. We investigated the molecular signaling pathways, which include: (1) survival signaling, IGFs-IGFIR-Akt-Bcl2 and proliferative signaling, cell cycle factors and MAPK pathways. (2) migrate and anti-scar signaling, FGF-2-uPA-MMPs. After treatment with different concentrations (20 μg/ml, 40 μg/ml, 60 μg/ml, 80 μg/ml, and 100 μg/ml) of dangshen. We observed a dose dependent proliferative effect using PCNA Western blotting assay, MTT assay and the wound healing test. We also found that dangshen stimulates the protein expressions of IGF-I pathway regulators, cell cycle controlling proteins and excites the MAPK signaling pathway regulators ERK and P38. Dangshen even stimulates the FGF-2-uPA-MMP 9 migration pathway in RSC 96 Schwann cells. Using MAPK chemical inhibitors, U0126, SB203580, and SP600125, the proliferative effects of dangshen on RSC 96 cells were identified to be ERK- and P38- dependent. Based on these results, applying an appropriate dose of dangshen with biomedical materials would be a potential approach for enhancing neuron regeneration.
