Abstract:

urrants and Sultanas (Vitis vinifera L.) are dried vine products produced in Greece and used broadly in the Mediterranean diet. We aimed to investigate the gastric cancer preventive activity of methanol extracts obtained from currants from three different origins in Greece (Vostizza, Nemea, and Messinia) as well as methanol extracts obtained from Sultanas cultivated in the island of Crete as to inhibition of cell proliferation, induction of apoptosis, and inhibition of inflammation. All extracts from 500 microg dried raisins studied suppressed cell proliferation, significantly those obtained from Sultanas from Crete and currants from Nemea. Flow cytometric analysis of Annexin-V labeled cells indicated that Cretan Sultana, Nemea, and Messinia currants at 500 microg dried product/ml medium significantly induced cell death. All extracts from 500 microg dried raisins statistically decreased protein and mRNA levels of ICAM-1 in TNF-alpha stimulated cells. Measurement of IL-8 protein levels and quantification for IL-8 mRNA showed no significant decrease. These results indicate that the methanol extracts from currants, rich in phenolic compounds, exhibit cancer preventive efficacy by limiting cell proliferation, inducing cell death, and suppressing ICAM-1 levels in AGS cells.
