Abstract

Insights

Astragalus radix, a Traditional Chinese Medicine, demonstrated significant anti-tumor effects against ovarian cancer cells in vitro. This herbal extract reduced cell viability and increased apoptosis, showing therapeutic potential.

Area of Science:

  • Integrative oncology
  • Pharmacology
  • Molecular biology

Background:

  • Ovarian cancer is a lethal gynecological malignancy often diagnosed late and resistant to conventional treatments.
  • Traditional Chinese Medicine (TCM) offers potential complementary strategies for cancer therapy.
  • This study explores the in vitro anti-tumor activity of a specific TCM herbal extract against ovarian cancer.

Purpose of the Study:

  • To investigate the anti-tumor effects of Astragalus radix extract on ovarian cancer cell lines.
  • To examine the impact of the extract on cell viability and apoptosis.
  • To explore the molecular interaction between a key compound (quinacetol) and a relevant ovarian cancer target (PI3K).

Main Methods:

  • Ovarian cancer cell lines (OVCAR-3, SK-OV-3) were treated with Astragalus radix extract.
  • Cell viability was assessed using MTT assay; apoptosis was measured by flow cytometry (Annexin V/PI staining).
  • Molecular docking and dynamics simulations were performed to analyze quinacetol-PI3K interactions.

Main Results:

  • Astragalus radix extract significantly reduced ovarian cancer cell viability in a dose- and time-dependent manner.
  • Increased rates of apoptosis were observed in treated ovarian cancer cells compared to controls.
  • Quinacetol showed favorable binding to the PI3K active site (-6.9 kcal/mol) with stable complex formation under physiological conditions.

Conclusions:

  • Astragalus radix extract demonstrates potent in vitro anti-tumor activity against ovarian cancer cells.
  • The findings suggest Astragalus radix as a potential adjunct or alternative therapeutic option for ovarian cancer.
  • Further in vivo and clinical studies are necessary to validate efficacy and safety in patients.
