Background:
Sauchinone is extracted from the root of Saururus chinensis and exhibits potent antitumor effects in various human cancers. However, how sauchinone is involved in breast cancer has not been well studied.
Methods:
Cells apoptosis, cell proliferation, and cycle distribution were evaluated. Xenograft tumor mouse model was constructed to investigate the roles of sauchinone. The relevant protein expression was detected by western blot.
Results:
We found that sauchinone significantly reduced proliferation and survival, also induced apoptosis of MCF-7 and Bcap-37 cells in vitro. Sauchinone significantly increased miR-148a-3p expression, and human epidermal growth factor receptor (HER)-2 targeted on miR-148a-3p. Sauchinone exposure downregulated HER-2 expression whose overexpression partly eliminated the inhibitory effect of sauchinone. Further, sauchinone efficiently inhibited breast cancer progression through downregulating HER-2 expression in vivo.
Conclusion:
Our results indicate that sauchinone efficiently inhibits breast cancer progression through regulating miR-148a-3p/HER-2 axis, suggesting that sauchinone could be an effective anticancer agent for breast cancer.
Insights
Sauchinone, derived from Saururus chinensis, effectively inhibits breast cancer progression by downregulating human epidermal growth factor receptor (HER)-2. This natural compound shows promise as an anticancer agent for breast cancer treatment.
Area of Science:
- Oncology
- Molecular Biology
- Pharmacology
Background:
- Sauchinone, extracted from Saururus chinensis root, possesses known antitumor properties.
- The specific role of sauchinone in breast cancer remains underexplored.
Purpose of the Study:
- To investigate the effects of sauchinone on breast cancer cells in vitro and in vivo.
- To elucidate the molecular mechanisms underlying sauchinone's action in breast cancer.
Main Methods:
- In vitro assays evaluated cell apoptosis, proliferation, and cell cycle distribution.
- Western blot analysis detected relevant protein expression.
- A xenograft mouse model was used to assess in vivo efficacy.
Main Results:
- Sauchinone reduced proliferation and survival while inducing apoptosis in breast cancer cell lines (MCF-7, Bcap-37).
- Sauchinone upregulated miR-148a-3p, which targets human epidermal growth factor receptor (HER)-2.
- Sauchinone downregulated HER-2 expression, inhibiting breast cancer progression in vitro and in vivo.
Conclusions:
- Sauchinone inhibits breast cancer progression by regulating the miR-148a-3p/HER-2 axis.
- Sauchinone demonstrates potential as an effective anticancer agent for breast cancer.
