Aim:
To investigate the effect of beta-ionone on the growth and apoptosis of gastric adenocarcinoma cell line SGC-7901.
Methods:
Using MTT, fluorescence dye (Hoechst-33258), transmission electron microscopy and the TUNEL assay, we examined growth and apoptosis of SGC-7901 cells treated with beta-ionone at various concentrations (i.e. 25, 50, 100 and 200 micromol/L) for 24 h, 48 h.
Results:
The growth of SGC-7901 cells was inhibited by beta-ionone. Seven days after treatment with beta-ionone at four concentrations, the inhibition rates were 12.04%, 30.59%, 78.25% and 94.15%, respectively. The IC(50) value of beta-ionone for SGC-7901 cells was estimated to be 89 micromol/L. The apoptotic morphology was demonstrated in SGC-7901 cells treated with beta-ionone by Hoechst-33258 staining and electron microscopy. Apoptosis was also shown in beta-ionone-treated SGC-7901 cells by the TUNEL assay.
Conclusion:
beta-ionone can inhibit cell proliferation and induce apoptosis of SGC-7901 cells. However, the mechanism needs to be further investigated.
Insights
Beta-ionone effectively inhibits gastric adenocarcinoma (SGC-7901) cell growth and induces apoptosis. Further research is needed to fully understand the underlying mechanisms of its anti-cancer effects.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Gastric adenocarcinoma is a significant global health concern.
- Identifying novel therapeutic agents for gastric cancer is crucial.
- Beta-ionone is a naturally occurring compound with potential anti-cancer properties.
Purpose of the Study:
- To evaluate the anti-proliferative and apoptotic effects of beta-ionone on the SGC-7901 gastric adenocarcinoma cell line.
- To determine the dose-dependent response of SGC-7901 cells to beta-ionone treatment.
Main Methods:
- Cell viability was assessed using the MTT assay.
- Apoptosis was detected through Hoechst-33258 staining, transmission electron microscopy, and the TUNEL assay.
- SGC-7901 cells were treated with varying concentrations of beta-ionone (25-200 µmol/L) for 24 and 48 hours.
Main Results:
- Beta-ionone significantly inhibited SGC-7901 cell proliferation in a dose-dependent manner, with IC(50) of 89 µmol/L.
- Morphological and molecular evidence confirmed beta-ionone-induced apoptosis in treated cells.
- High inhibition rates (up to 94.15%) were observed at the highest concentrations.
Conclusions:
- Beta-ionone demonstrates potent anti-proliferative and pro-apoptotic activity against gastric adenocarcinoma cells (SGC-7901).
- These findings suggest beta-ionone as a potential candidate for gastric cancer therapy.
- The precise molecular mechanisms underlying beta-ionone's effects require further investigation.
