Abstract

Insights

Diosgenin glucoside (DG) from Trillium tschonoskii Maxim inhibits osteosarcoma cell growth, migration, and invasion. DG promotes apoptosis and cell cycle arrest via the PI3K/AKT/mTOR pathway, offering a potential anti-cancer therapeutic strategy.

Area of Science:

  • Pharmacology
  • Molecular Biology
  • Oncology

Background:

  • Trillium tschonoskii Maxim (TTM) exhibits antitumor properties.
  • The specific antitumor mechanisms of Diosgenin glucoside (DG), a compound from TTM, remain unclear.

Purpose of the Study:

  • To investigate the anti-tumor effects of DG on osteosarcoma MG-63 cells.
  • To elucidate the molecular mechanisms underlying DG's action in osteosarcoma.

Main Methods:

  • Cell proliferation, apoptosis, and cell cycle were assessed using CCK-8, HE staining, and flow cytometry.
  • Cell migration and invasion were evaluated through wound healing and Transwell assays.
  • Molecular mechanisms were explored via immunohistochemistry, Western blot, and RT-PCR.

Main Results:

  • DG significantly inhibited osteosarcoma cell proliferation and activity.
  • DG induced apoptosis and G2 phase cell cycle arrest, while suppressing migration and invasion.
  • DG downregulated the PI3K/AKT/mTOR signaling pathway, inhibiting S6K1 and eIF4F expression.

Conclusions:

  • DG demonstrates significant anti-osteosarcoma effects by inhibiting proliferation, migration, invasion, and promoting apoptosis.
  • The PI3K/AKT/mTOR signaling pathway is implicated in DG's anti-tumor activity in osteosarcoma cells.
