Influence of Olive Extracts on the Expression of Genes Involved in Lipid Metabolism in Medaka Fish.

. To assess the possible effect of polyphenol-rich olive extracts on lipid metabolism in medaka fish by quantifying the expression of lipogenic and lipolytic genes. .

Protection by polyphenol extract from olive stones against apoptosis produced by oxidative stress in human neuroblastoma cells.

Objective: We evaluated the protective activity of an extract from a by-product such as olive stones, through its ability to inhibit H202 induced apoptosis in the SH-SY5Y human neuroblastoma cell line.

Material And Methods: To such end, 20,000 cells/well were cultivated and differentiation with retinoic acid was initiated. Once the cells were differentiated, apoptosis was induced with and without H2O2 extract.

Anti-adipogenic activity of an olive seed extract in mouse fibroblasts.

Unlabelled: The administration of different polyphenols protects against increased body weight and fat accumulation. The aim of the study was to determine the anti-adipogenic activity of an olive-seed polyphenolic extract, by means of mouse fibroblast cell line 3T3-L1 adipocyte differentiation.

Material And Methods: Cells were incubated and differentiated (6000 cells/cup) in the presence of olive-seed extract at 10 and 50 mg/l biosecure concentrations of polyphenols, and with no extract in the control sample.
