"A fundamental aspect to be taken into account is that epigenetic changes can possibly be reversed by modifying epigenetic factors, such as diet and lifestyle. Nowadays, identification of these factors is crucial to develop epigenetically-based preventions and more effective anti-cancer intervention strategies."
"Virtually, all dietary compounds have the ability to act at the epigenetic level in cancer cells thus influencing the epigenome in a positive or negative way. Particularly, plant derived compounds, such as polyphenols, have the capacity to reverse adverse epigenetic mutations in cancer cells, to inhibit tumorigenesis progression, to prevent the metastatic process or to sensitize cancer cells to chemo and radiotherapy (Vanden Berghe, 2012)."
- Cancer stem cells (CSCs) are chemo-radiotherapy resistant, causing tumor relapse.
- CSCs are known to reside within specific hypoxic and acidic tumor niches.
- Phytocompounds affect CSC self-renewal, metabolism and microenvironment.
- Phytocompounds might be exploited for cancer prevention and treatment.
