Soluble extract from Moringa oleifera leaves with a new anticancer activity

Area of Science:

• Phytochemistry
• Oncology
• Molecular Biology

Background:

• Moringa oleifera (MOL) is traditionally used for medicinal purposes.
• Recent research explores its antimicrobial, anticancer, anti-inflammatory, antidiabetic, and antioxidant properties.
• Studies often focus on simple biological effects and chemical compositions, necessitating further investigation into specific therapeutic applications.

Purpose of the Study:

• To evaluate the potential of soluble Moringa oleifera leaf (MOL) extracts as novel anticancer drug candidates.
• To assess the efficacy of MOL extracts in inhibiting cancer cell proliferation and invasion.
• To investigate the molecular mechanisms underlying the anticancer effects of MOL extracts.

Main Methods:

• Preparation of soluble cold distilled water extract from MOL.
• Treatment of human lung cancer cells and other cancer cell lines with MOL extract (300 µg/mL at 4°C).
• Assessment of apoptosis induction, tumor cell growth inhibition, reactive oxygen species (ROS) levels, gene expression changes, and rRNA degradation.
• Comparative cytotoxicity analysis between tumor cells and normal cells.

Main Results:

• MOL extract significantly induced apoptosis and inhibited tumor cell growth in various cancer cell lines.
• Treatment with MOL extract reduced intracellular reactive oxygen species (ROS) levels.
• Over 90% of tested genes were downregulated more than 2-fold in MOL-treated cells, with dose-dependent rRNA degradation observed.
• MOL extract exhibited greater cytotoxicity towards tumor cells than normal cells.

Conclusions:

• Soluble MOL extract demonstrates significant anticancer potential by inducing apoptosis and inhibiting cancer cell proliferation and invasion.
• The observed gene downregulation and rRNA degradation suggest a novel mechanism of action for MOL extract.
• MOL extract shows promise as a targeted, natural therapeutic candidate for various types of cancer.
