Evaluation of the Anti-Metastatic Effect of Foeniculum Vulgare on the Protein Expression of HSP 70 & 90 in Balb/c Mice with 4t1 Model of Breast Cancer.

INTRODUCTION

Breast cancer is one of the important factors of cancer-related deaths. Considering the drug resistance, special attention has been paid to natural compounds. This study aimed at evaluating the anti-metastatic activity of fennel in a breast cancer mouse model.

METHODS

A total of 35 adult female BALB/C mice were used in this study. Breast cancer was induced by subcutaneous injection of 4T1 cells in the right lower flank. The mice received fennel extracts daily via intraperitoneal injection for two weeks. Meanwhile, tumor volume was measured every day using calipers. After two weeks, each animal was anesthetized. The protein expression of HSP 70 & 90 was measured in liver tissue and ovary. The expression of her2 was measured in tumor tissue. The activity of Glutathione peroxidase and reductase as anti-oxidant agents were measured in serum.

RESULTS

Tumor size significantly decreased after nine days' treatment of the fennel. The expression of HER2 increased in the tumor tissue and decrease with different dose of fennel. Fennel treatment caused a decrease in the protein expression of HSP 70 & 90 in the liver tissues.

CONCLUSION

Based on our findings, fennel has anti-tumor and anti-metastatic activities against aggressive cancers.
