Abstract:
Goniothalamin is a biologically active styrylpyrone derivative isolated from various Goniothalamus species. The ability of goniothalamin to induce apoptosis via caspase-3 activation against hepatoblastoma (HepG2) and normal liver cells (Chang cells) was studied using morphological and biochemical evaluations. HepG2 and Chang cells were treated with goniothalamin for 72 h and analysed by TUNEL and Annexin-V/PI staining. Furthermore, the post-mitochondrial caspase-3 was quantified using ELISA. In view of our results, goniothalamin induced apoptosis on treated cells via alteration of cellular membrane integrity and cleavage of DNA. On the other hand, post-mitochondrial caspase-3 activity was significantly elevated in HepG2 cells treated with goniothalamin after 72 h. These findings suggest that goniothalamin induced apoptosis on HepG2 liver cancer cells via induction of caspase-3 with less sensitivity on the cell line of Chang cells.
Insights
Goniothalamin induces apoptosis in liver cancer cells (HepG2) by activating caspase-3. This natural compound shows less sensitivity towards normal liver cells (Chang cells), suggesting potential therapeutic applications.
Area of Science:
- Natural Product Chemistry
- Molecular Biology
- Cancer Research
Background:
- Goniothalamin is a styrylpyrone derivative from Goniothalamus species.
- It exhibits biological activity, prompting investigation into its anti-cancer mechanisms.
Purpose of the Study:
- To investigate goniothalamin's ability to induce apoptosis in hepatoblastoma (HepG2) and normal liver (Chang) cells.
- To determine the role of caspase-3 activation in goniothalamin-induced cell death.
Main Methods:
- Cells (HepG2 and Chang) were treated with goniothalamin for 72 hours.
- Apoptosis was assessed using TUNEL and Annexin-V/PI staining.
- Caspase-3 activity was quantified via ELISA.
Main Results:
- Goniothalamin induced apoptosis in treated cells, evidenced by altered membrane integrity and DNA cleavage.
- Significant elevation of caspase-3 activity was observed in HepG2 cells post-treatment.
- Chang cells exhibited less sensitivity to goniothalamin-induced apoptosis.
Conclusions:
- Goniothalamin effectively induces apoptosis in HepG2 liver cancer cells.
- Caspase-3 activation is a key mechanism in goniothalamin's cytotoxic effect on liver cancer cells.
- The compound demonstrates a differential sensitivity, being less potent against normal liver cells.
