Hypothesis
The study aims to evaluate the antiproliferative activity of Cinnamomum cassia constituents in Hep G2 cells and the effects of pifithrin-alpha on their apoptotic signaling pathways.
Conclusion
Cinnamaldehyde was found to be the most potent antiproliferative compound, inducing apoptosis in Hep G2 cells through p53 and CD95 signaling pathways.
Supporting Evidence
- Cinnamaldehyde showed an IC50 of 9.76 μM, comparable to the anti-cancer drug 5-fluorouracil.
- Cinnamaldehyde treatment resulted in a significant increase in apoptotic cells.
- Pifithrin-alpha significantly inhibited the apoptotic effects of cinnamaldehyde.
Takeaway
Cinnamaldehyde from cinnamon can help kill liver cancer cells, and a certain inhibitor can stop this process.
Methodology
The antiproliferative activity was measured using XTT assay, and apoptosis-related proteins were detected by western blotting.
