Summary of article contents:
Introduction
This study investigates the effects of Gallic Acid (GA) on the prostate cancer cell line PC3, particularly focusing on its interaction with important apoptotic factors such as BAD, BAK, and BIM. GA, a plant-derived polyphenolic compound, has been recognized for its antioxidant properties and potential anticancer effects. The research employs comet assays to assess DNA damage and in-silico simulations using Auto Dock and Gromacs to analyze the molecular interactions of GA with apoptotic proteins.
Induction of Apoptosis by Gallic Acid
The findings suggest that GA effectively induces apoptosis in PC3 cells, with an IC50 value determined to be 35 μM. Comet assay results demonstrate a dose-dependent increase in DNA damage, confirmed by the rise in the tail-to-head ratio in the electrophoresis images. The simulations further reveal that GA forms hydrogen bonds with BAD, leading to structural instability in the protein, which is crucial for apoptosis. This highlights GA's role in modulating apoptotic pathways, indicating its potential as a therapeutic agent for prostate cancer through the activation of apoptotic factors.
Conclusion
In conclusion, Gallic Acid has demonstrated significant efficacy in inducing apoptosis in prostate cancer cells by promoting DNA damage and destabilizing apoptotic factors. The molecular dynamics simulations corroborate the in vitro findings, establishing GA as a promising natural compound for anticancer therapy. The study underscores the importance of exploring natural antioxidants like GA to develop effective treatments for cancer while also enhancing our understanding of the underlying molecular mechanisms involved in apoptotic processes.
