Aim:
Ovarian cancer is one of most common malignancies in women and is associated with high reoccurrence rate and poor prognosis. This study is designed to investigate the anti-tumor effects of amentoflavone (AF), one of the major active ingredients of S. tamariscina, against ovarian cancer.
Materials And Methods:
Human ovarian cancer cell lines SKOV3 and OVCAR-3 were used in this study. The effect of AF on cell viability was examined by CCK-8 assay. Cell apoptosis and cell cycle distribution was determined by flow cytometry. ROS generation was detected using fluorescent staining. Expression of signaling molecules was determined by western blots. Xenograft model was established to evaluate the therapeutic efficacy of AF in vivo.
Key Findings:
Our results showed that AF could significantly suppress cell proliferation, induce apoptosis and block cell cycle progression. Mechanistically, downregulation of S-phase kinase protein 2 (Skp2) by AF contributed to its anti-tumor effect against ovarian cancer. Furthermore, our results showed that AF repressed the expression of Skp2 through ROS/AMPK/mTOR signaling. The anti-tumor effect of AF against ovarian cancer was also confirmed in a xenograft animal model.
Significance:
Overall, our present findings highlighted the potential of AF in the treatment of ovarian cancer. Moreover, our study also provided a new elucidation regarding the anti-tumor mechanisms of AF.
Insights
Amentoflavone (AF) effectively suppresses ovarian cancer cell growth and promotes apoptosis. This natural compound works by downregulating Skp2 expression via the ROS/AMPK/mTOR pathway, showing therapeutic potential for ovarian cancer treatment.
Area of Science:
- Oncology
- Pharmacology
- Molecular Biology
Background:
- Ovarian cancer is a leading cause of cancer-related deaths in women, characterized by high recurrence rates and poor prognosis.
- Amentoflavone (AF), a natural compound from S. tamariscina, is investigated for its anti-cancer properties.
Purpose of the Study:
- To investigate the anti-tumor effects of amentoflavone (AF) against human ovarian cancer cell lines.
- To elucidate the underlying molecular mechanisms of AF's anti-cancer activity.
Main Methods:
- Utilized human ovarian cancer cell lines (SKOV3, OVCAR-3) and a xenograft mouse model.
- Assessed cell viability (CCK-8), apoptosis and cell cycle (flow cytometry), ROS generation, and protein expression (Western blot).
Main Results:
- AF significantly inhibited ovarian cancer cell proliferation, induced apoptosis, and caused cell cycle arrest.
- AF downregulated S-phase kinase protein 2 (Skp2) expression, a key mechanism for its anti-tumor effect.
- AF repressed Skp2 expression through the ROS/AMPK/mTOR signaling pathway, confirmed in vivo.
Conclusions:
- Amentoflavone (AF) demonstrates significant potential as a therapeutic agent for ovarian cancer.
- The study elucidates AF's anti-tumor mechanisms involving Skp2 downregulation via ROS/AMPK/mTOR signaling.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
