Breast cancer is the most common malignancy in the world with the highest rate of morbidity and mortality. Due to the several side effects of chemotherapy and radiotherapy, recent studies have focused on the use of herbal medicines. Epidemiological reports have shown the inverse relationship between breast cancer risk and intake of olive. Oleuropein (OLE) is a polyphenolic compound in virgin olive oil with antineoplastic properties and it is well tolerated by humans. Recent reports have shown that OLE has effects on the control of cancer by modulating epigenetics, such as histone deacetylase (HDAC) inhibition. However, the epigenetic mechanisms of OLE anticancer properties are yet to be properly investigated. Therefore, this study aimed to determine the therapeutic effects of OLE through the modulation of histone deacetylase 2 (HDAC2) and histone deacetylase 3 (HDAC3) expression in breast cancer cell line. MCF-7 cells were tested with and without OLE, and also the cell viability, apoptosis, and migration were examined. HDAC2 and HDAC3 expression genes were assessed by quantitative real-time polymerase chain reaction. It was found that OLE decreased the expression of both HDAC2 and HDAC3 (P < 0.05), induced apoptosis and retarded cell migration and cell invasion in a dose-dependent manner (P < 0.05). These results showed that OLE is a potential therapeutic and preventive agent for breast cancer.
