【Abstract】 Objective:To study the effects of ginsenoside Rh2 on proliferation,migration and EMT of esophageal cancer cell Eca-109 and its mechanism.Methods:CCK-8 method was used to detect the effects of ginsenoside Rh2 on the proliferation of Eca-109 cells.Cell scratches assay was used to detect the mobility of Eca-109 cells.Western blot was used to detect the expression levels of E-cadherin,Vimentin and Slug proteins related to EMT.Results:The results showed that ginsenoside Rh2 could significantly inhibit the proliferation of Eca-109 cells in a dose-dependent manner.In addition,ginsenoside Rh2 significantly inhibited the protein expression of E-cadherin,Vimentin and Slug,and inhibited the migration of Eca-109 cells.Ginsenoside Rh2 significantly decreased the protein expression of Egr-1,TRL4 and mTOR.The results showed that ginsenoside Rh2 inhibited the proliferation,migration and EMT of Eca-109 cells via inhibiting Egr-1/TRL4/mTOR signaling pathway.Conclusion:Ginsenoside Rh2 inhibits the proliferation,migration and EMT of esophageal cancer cell Eca-109 by mediating Egr-1/TRL4/mTOR signaling pathway.This result provides a molecular basis for further research on the treatment of esophageal cancer.更多还原
