Abstract:
Pro-senescence therapy is a recently proposed anti-cancer strategy and has been shown to effectively inhibit cancer. Resveratrol is gaining attention for its cancer preventive and suppressive properties. The mechanisms of resveratrol in cancer suppression by inducing cancer cell senescence are unclear. Our results showed that resveratrol induced cell senescence along with an increase of SA-β-Gal activity and inhibition of colony formation in breast and lung cancer cells. The underlying mechanisms were that resveratrol induced ER-stress by increasing SIRT1 to promote p38MAPK expression and by reducing NO level to up-regulate DLC1 expression, and ER-stress further resulted in DNA damage and mitochondrial dysfunction, eventually leading to cancer cell senescence. Our findings on resveratrol's induction of cancer cell senescence via activating ER-stress through the SIRT1/p38MAPK and NO/DLC1 pathways provide a solid base for its clinical application and its preventive application as a food additive.
Insights
Resveratrol induces cancer cell senescence, a new anti-cancer approach, by activating ER-stress. This research clarifies resveratrol
Area of Science:
- Oncology
- Cell Biology
- Molecular Biology
Background:
- Pro-senescence therapy is an emerging anti-cancer strategy.
- Resveratrol exhibits potential cancer-preventive and suppressive properties.
- The precise mechanisms by which resveratrol induces cancer cell senescence remain largely unknown.
Purpose of the Study:
- To elucidate the molecular mechanisms underlying resveratrol-induced cancer cell senescence.
- To investigate the role of ER-stress in resveratrol's anti-cancer effects.
Main Methods:
- Assessed resveratrol's effect on senescence markers (SA-β-Gal activity, colony formation) in breast and lung cancer cells.
- Investigated the involvement of SIRT1, p38MAPK, NO, and DLC1 in resveratrol-induced ER-stress.
- Examined the downstream consequences of ER-stress, including DNA damage and mitochondrial dysfunction.
Main Results:
- Resveratrol induced cancer cell senescence, evidenced by increased SA-β-Gal activity and inhibited colony formation.
- Resveratrol triggered ER-stress by modulating SIRT1/p38MAPK and NO/DLC1 pathways.
- ER-stress subsequently led to DNA damage and mitochondrial dysfunction, culminating in senescence.
Conclusions:
- Resveratrol effectively induces cancer cell senescence through ER-stress activation via the SIRT1/p38MAPK and NO/DLC1 pathways.
- These findings support resveratrol's potential for clinical cancer therapy and preventive use as a food additive.
