Objective:
To investigate apoptosis of BEL-7402 cells induced by Galangin.
Methods:
Cytotoxicity and cell viability were assayed by MT methods. Morphologic assessment of apoptosis was performed by fluorescence microscope, cell cycle and mitochondrial membrane potential were analyzed by flow cytometry, Caspases Activities were detected by chromogenic substrate assay.
Results:
BEL-7402 cells treated with Galangin showed apparently cytotoxicity, IC50 of Galangin was 30.15 mg/L The growth curve showed that the ratio of growth decreased with the increasing of concentration of Galangin. The apoptosis appeared 24 hours after treated with 20-80 mg/L Galangin, morphologic changes included nuclear chromatin condensation and fluorescence strength was observed with fluorescence microscope. The activity of Caspase-9 attained to peak value at 6 h, while Caspase-6 activity was up to peak value at 12h and Caspase-3 activity attained to peak value at 18 h.
Conclusion:
Galangin may induce BEL-7402 cells apoptosis by mitochondrial pathway.
Insights
Galangin, a natural compound, induces apoptosis in BEL-7402 liver cancer cells. This occurs through the mitochondrial pathway, impacting cell viability and growth.
Area of Science:
- Biochemistry
- Cell Biology
- Pharmacology
Context:
- Hepatocellular carcinoma (HCC) remains a significant global health challenge.
- Exploring natural compounds for novel anti-cancer therapies is crucial.
- Galangin, a flavonoid, has shown potential anti-cancer properties.
Purpose:
- To investigate the apoptotic effects of Galangin on BEL-7402 liver cancer cells.
- To elucidate the mechanism of Galangin-induced apoptosis.
Summary:
- Galangin demonstrated significant cytotoxicity against BEL-7402 cells with an IC50 of 30.15 mg/L.
- Apoptosis was observed after 24 hours of treatment, characterized by nuclear condensation.
- Flow cytometry revealed cell cycle arrest and disruption of mitochondrial membrane potential.
- Galangin modulated the activity of key caspases (Caspase-9, -6, and -3), indicating activation of the apoptotic cascade.
- The study suggests Galangin induces apoptosis via the mitochondrial pathway.
Impact:
- Provides evidence for Galangin as a potential therapeutic agent against HCC.
- Highlights the mitochondrial pathway as a key target for Galangin's anti-cancer effects.
- Contributes to understanding the molecular mechanisms of flavonoid-induced apoptosis.
