【 摘 要 】

BackgroundElaeagnus umbellata is a plant commonly used in traditional Asian medicine for its many health benefits and strong antioxidative activity. Its therapeutic potential is believed to be connected to its effect on fibroblasts. This study aimed to investigate E. umbellata methanol-acetone extract’s (EUE) defense against hydrogen peroxide (H2O2)-induced fibroblast damage.MethodsBecause the main biologically active compounds of E. umbellata are water-insoluble, we evaluated the effects of methanol-acetone fruit extracts using liquid chromatography (for ascorbic acid and beta-carotene) and spectrophotometry (for lycopene and total phenolics). The extract’s antioxidative activity was measured using DPPH radical inhibition, and EUE’s effect on human fibroblasts was also evaluated. We assessed the metabolic activity and apoptosis of HFFF-2 fibroblasts exposed to EUE and/or H2O2using the XTT test and flow cytometry, respectively. Superoxide dismutase activity and reactive oxygen species (ROS) production were evaluated using colorimetric and fluorometric assays, respectively. We measured pro-inflammatory cytokine (MIF, fractalkine, MCP-4, BLC, GCP-2, NAP-2, Eotaxin-2, and Eotaxin-3) expression in HFFF-2 cells using immunocytochemistry.ResultThe extract increased HFFF-2 cell proliferation and reduced cell death caused by H2O2-induced stress. H2O2-treated fibroblasts had greater ROS production than cells treated with both H2O2 and EUE. Additionally, the group treated with H2O2 alone showed higher pro-inflammatory cytokine (MIF, MCP-4, NAP-2, Eotaxin-2, and Eotaxin-3) expression.ConclusionEUE protected human fibroblasts from H2O2-induced oxidative stress and reduced the fibroblast-mediated inflammatory response triggered by ROS.
