The effect of Dendrobium officinale extract in inhibiting the senescence of H2O2‐induced fibroblasts based on the senescence‐associated secretory phenotype

Abstract

AbstractBackgroundDendrobium officinale is widely used for a long time in China, with effect of antioxidation, antitumor, enhancing immunity and so on. In recent years, Dendrobium officinale has been gradually used in cosmetics due to its powerful beauty effects.AimsBased on senescence‐associated secretory phenotype (SASP), we studied the antiaging effect of Dendrobium officinale extract (DOE) on skin.MethodsThe senescent model of human skin fibroblasts was established by the induction of H2O2, and the content of SASP factors was tested after the treatment of DOE, such as interleukin‐6 (IL‐6), monocyte chemoattractant protein‐1 (MCP‐1) and matrix metalloproteinase‐1 (MMP‐1).ResultsIt was found that after the treatment with different concentrations of DOE, the contents of IL‐6, MCP‐1 and MMP‐1 all decreased in different degrees.ConclusionsIt indicated that DOE could inhibit the secretion of SASP factors and was a promising natural antiaging agent.
