Abstract

Background: About angiogenesis, metastasis of breast cancer and exercise, Many studies have been done in recent decades to better understand of regulatory mechanisms. The purpose of this study was to investigate the Interactive effect of high-intensity interval training (HIIT) and quercetin supplementation (Q) on the expression of key angiogenic factors in tumor tissue of mouse with breast cancer. Methods: Twenty-four female Balb/C mouse were injected with estrogen receptor-dependent breast cancer cells MC4L2 and then divided into three groups of tumor (T), tumor + of high-intensity interval training (TH) and tumor + high-intensity interval training + quercetin (THQ). The TH and THQ groups ran the treadmill 3 days a week for 6 weeks and each session 1 hour. The THQ group received 110 mg/ kg quercetin solution for 6 weeks, 3 days a week with training. After completion of the work, the mouse were sacrificed and their tumor tissue removed and frozen in liquid nitrogen And stored at-70 ° C. Expression of TIE-2 and VEGF-A genes was measured by REAL TIME-PCR. ΔCt, ΔΔCt, and Fold change were calculated with the relevant statistical tests at the significant level (P <0.05) by GENEX software. Results: The results showed that THQ interaction significantly decreased the expression of TIE-2 and VEGF-A genes in TH and THQ groups compared to T group. In addition, quercetin in THQ group significantly decreased TIE-2 and VEGF-A gene expression compared to TH group. Conclusion: interaction of HIIT and Q supplementation are probably effective in inhibiting tumor angiogenesis. © 2021 The Author.
