Ginsenoside Rk1 Enhances Chemosensitivity of Gastric Cancer Through Activating the AMPK/mTOR Pathway
Objectives Ginseng and its extracts have shown promising therapeutic effects on gastric cancer (GC). We aimed to investigate the functions and potential mechanisms of Ginsenoside Rk1 (Rk1) on GC. Methods GC cell lines were treated with different doses of Rk1. The CCK-8 assay and BrdU assay were used...

| description | Objectives Ginseng and its extracts have shown promising therapeutic effects on gastric cancer (GC). We aimed to investigate the functions and potential mechanisms of Ginsenoside Rk1 (Rk1) on GC. Methods GC cell lines were treated with different doses of Rk1. The CCK-8 assay and BrdU assay were used to measure cell viability and proliferation. A Transwell assay was used to evaluate cell invasion and migration. A TUNEL assay was used to assess cell apoptosis. RT-PCR was conducted to detect apoptosis-associated genes. Western blotting was used to determine the activation of the AMPK/mTOR pathway. An in vivo tumor-bearing nude mouse model was generated to investigate the impact of Rk1 on tumor growth. Results Rk1 inhibited the proliferation, migration, invasion, and EMT of GC cells and promoted cell apoptosis. It also enhances the sensitivity of GC cells to chemotherapy drugs (including 5-fluorouracil, vincristine, cisplatin, and oxaliplatin). Mechanistically, Rk1 increased AMPK phosphorylation and repressed mTOR phosphorylation. AMPK inhibition strongly decreased the inhibitory effect of Rk1 on GC cells. In-vivo assays suggested that Rk1 considerably hindered GC growth and had synergistic effects when combined with cisplatin or oxaliplatin. Conclusion Ginsenoside Rk1 exerts an antitumor effect on GC by activating the AMPK/mTOR pathway. |
