ABSTRACT |
Objectives: The purpose of this study was to investigate the effect of FS for the modulation of ROS and MMP in a hypoxic model of cultured rat cortical cells.
Methods : For the effect of FS on the viability, FS was added to culture media (neurobasal supplemented with B27) and cell viability was measured by LDH assay. To investigate the effects of FS on ROS generation and MMP preservation, cells grown in FS-containing media were given a hypoxic shock(2% O2/5% CO2, 37℃, 3 hrs) on DIV 10, stained with H2DCF-DA(10 nM) and JC-1, respectively, and observed by fluorescent microscope.
Results: 1. FS has a protective effect of cortical cells in both normoxia and hypoxia. 2. FS reduced the generation of ROS and this reduction was especially significant at 3 days after hypoxia. 3. FS was effective for the maintenance of MMP in hypoxia, and this efficacy was especially significant at 3 days after hypoxia.
Conclusions: Taken together, these results indicate that FS attenuates ROS generation and MMP dissipation, which eventually protects from neuronal cell death in hypoxia. |
