[Anti-proliferation and chemo-sensitization effects of apigenin on human lung cancer cells]
1Department of Biochemistry and Genetics, Zhejiang University School of Medicine, Hangzhou, China.
Objective:
To investigate the antitumor effect of apigenin on human lung cancer cells.
Methods:
The anti-proliferation and sensitization effects of apigenin on human lung cancer cells was accessed by counting cells after Trypan blue staining and MTS assay.
Results:
(1) Apigenin significantly suppressed the proliferation of four types of human lung cancer cells (A549:P=0.041, H460:P=0.050, LTEP-a2:P=0.039, H292:P=0.016); (2) Apigenin significantly increased the susceptibility of human lung cancer cells to antitumor drugs (P<0.05 or P<0.01) in a synergistic way (almost all of the combination index values are less than 1).
Conclusion:
Apigenin widely inhibits cell proliferation of various lung cancer cell lines in a dose-dependent manner and the combination treatment of apigenin and antitumor drugs is very effective in human lung cancer cells, and Nrf2-ARE pathway may contribute to the mechanism.
Insights
Apigenin, a natural compound, effectively inhibits lung cancer cell growth and enhances the efficacy of chemotherapy drugs. This suggests apigenin holds promise for novel lung cancer treatment strategies.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Context:
- Lung cancer remains a leading cause of cancer-related mortality worldwide.
- Novel therapeutic strategies are urgently needed to improve patient outcomes.
- Apigenin, a natural flavonoid, has demonstrated potential anticancer properties in various studies.
Purpose:
- To evaluate the antitumor effects of apigenin on human lung cancer cells.
- To investigate apigenin's ability to sensitize lung cancer cells to conventional chemotherapy.
- To explore the underlying mechanisms of apigenin's action.
Summary:
- Apigenin significantly inhibited the proliferation of multiple human lung cancer cell lines in a dose-dependent manner.
- Apigenin demonstrated a synergistic effect when combined with antitumor drugs, enhancing their efficacy.
- The Nrf2-ARE pathway is implicated as a potential mechanism contributing to apigenin's observed effects.
Impact:
- Apigenin exhibits broad-spectrum antiproliferative activity against diverse lung cancer cell lines.
- Combination therapy involving apigenin and chemotherapy presents a promising strategy for enhanced lung cancer treatment.
- Further research into the Nrf2-ARE pathway could elucidate novel therapeutic targets for lung cancer.
