- Paper Abstract
- BACKGROUND: There have been many researches on the effects of flavonoids on tumor treatment or adjuvant therapy, but there are few studies revealing their epigenetic effect on tumors. Hesperetin is a common citrus flavanone widely distributed among citrus fruits. The role of hesperetin in gastric cancer metastasis is unclear. PURPOSE: To investigate the effect of hesperetin on gastric cancer metastasis and its underlying mechanism. METHODS: We used cancer cell lines cultured in medium and nude mice implantation as in vitro and in vivo models to investigate the impact of hesperetin treatment on the migration and invasion of gastric cancer cells. The molecular biological experiments such as transwell assay, western blotting, qPCR, ChIP-qPCR, immunostaining and transfection were conducted to explore the molecular mechanisms. RESULTS: We found that hesperetin obviously reduced the protein abundance of DOT1L and the methylation of histone H3K79 in a variety of cells. In gastric cancer cells, the treatment of hesperetin decreased cell migration and invasion and the expression of genes closely related to the metastatic capability. Mechanistically, hesperetin affected the stability of DOT1L protein by regulating the activity of CBP. CONCLUSION: These findings highlight the epigenetic effect of hesperetin and provide a new perspective to understand the tumor suppressive effect of flavonoids.
