dc.description.abstract | Purpose: It has been previously reported that breast tumor incidence, growth, and metastasis are stimulated by high-fat diet but reduced by caloric restriction. However, few studies have elucidated the effects of dietary change from a high-fat diet after breast cancer initiation. Therefore, in this study, we attempted to provide practical assistance to breast cancer prevention and management by investigating the effects of dietary change from a high-fat diet to normal diet on breast cancer growth and metastasis. Methods: The experimental animals were divided into 2 groups (high-fat diet control [HFC] group and diet restriction [DR] group) and consumed a high-fat diet for 8 weeks. 4T1 cells were transplanted into subcutaneous fat or tail vein to measure the growth and metastasis of breast cancer. The HFC and DR groups continuously ingested either high-fat diet or AIG-93G diet for 5 weeks or 3 weeks, respectively. Cell proliferation and apoptosis markers from tumor tissues were analyzed by Western blot analysis. The data were analyzed using the SPSS 25.0 package program. Results: The results show that the DR group significantly reduced breast tumor initiation, growth, and tumor tissue weight compared to the HFC group. The DR group suppressed tumor growth by decreasing proliferation and inducing apoptosis through down-regulation of Bcl-xL and up-regulation of caspase-3 activity. Furthermore, the DR group significantly reduced numbers of metastasized tumors in lung tissues. Conclusion: These results suggest that dietary change from a high-fat diet to normal diet decreased breast growth by reducing cell proliferation and inducing apoptosis and metastasis. Taken together, these results indicate that dietary change to a low-fat and balanced diet might suppress breast tumor growth and metastasis even after tumor diagnosis. | - |
