Introduction: Biological processes are regulated through epigenetics, including chromatin remodelling
(methylation, acetylation, etc.) and non coding RNAs. The correct balance of these mechanisms is crucial for
the maintenance of cellular homeostasis and its dysregulation is correlated to many disorders such as cancer.
Nutrient availability has a great impact on the metabolic pathways involved in cancer cell proliferation.
Incubation in Earle’s Balanced Salt Solution (EBSS), a culture medium containing 1% glucose in absence of
serum and amino acids, mimics the condition of starvation. Resveratrol (RV), a dietary polyphenol acting as
a protein (caloric) restriction mimetic makes the cells unable to uptake nutrients for their metabolism.
Results: Here, we report on the changes of the miRNAs in ovarian cancer cells subjected to amino acid
starvation or to RV. In this fasting condition, cancer cells promote autophagy as a pro-survival mechanism
and eventually exit the cell cycle to undergo a dormant state. RV has a major impact on miRNome involved
in autophagy and apoptosis compared to the one observed in EBSS-treated cells.
Conclusion: Our data support the view that RV treatment can be more effective than nutrient starvation,
thus it can substitute it in order to induce a dormant-like state in cancer cells.
