Dietary polyphenols, derived from natural products, have received a great interest for their chemopreventive properties against cancer. In this study, we investigated the effects of phenolic extract of the oleaster leaves (PEOL) on tumor growth in mouse model and on cell death in colon cancer cell lines. We assessed the effect of oleaster leaf infusion on HCT116 (human colon cancer cell line) x...

Dehydrins belong to a protein family whose expression may be induced or enhanced by developmental process and environmental stresses that lead to cell dehydration. A dehydrin gene named OesDHN was isolated and characterized from oleaster (Olea europaea L. subsp. europaea, var. sylvestris), the wild form of olive. To elucidate the contribution of OesDHN in the development of drought tolerance, i...

Olea europaea L. subsp. europaea var. sylvestris, also named oleaster, is the wild form of olive and it is used as rootstock and pollen donor for many cultivated varieties. An efficient procedure for in vitro propagation of oleaster was established in this study. A zeatin concentration of 2.5 mg/L was effective to induce an appreciable vegetative growth. Also high rooting efficiency was obtaine...

Using enzyme polymorphism at IO loci , genetic variation was analysed in both wi ld and cuiti vated olive growing around the Mediterranean Basin. Twenty five and 21 alle1es were observed in the 333 wild olive trees analysed and in the culti ved materia1 (418 trees) respectively. Twenty one of these alleles were common to the two forms. In addition, in most the situations of sympatry between wil...

A response to Breton, C., Tersac, M. & Bervillé, A. (2006) Genetic diversity and gene flow between the wild olive (oleaster, Olea europaea L.) and the olive: several PlioPleistocene refuge zones in the Mediterranean basin suggested by simple sequence repeats analysis. Journal of Biogeography, 33, 1916–1928. In a recent paper, Breton et al. (2006) provided interesting genetic data (mainly nuclea...

The Macedonian Kings and the Two Wreaths of Zeus This paper aims to investigate reasons why, since reign Philip II, “national” Zeus, venerated on Olympus Dion characterized by oak crown, was abandoned in favor Olympian Elis, olive/oleaster wreath. We notice that while members royal family display, life death, an wreath as insignia their kingship, at same time also a symbol highest divinity, kin...

Objective- To evaluate the healing potential of oleaster leave water soluble extract on skin wounds. Design- Experimental study. Animals- 30 male Spragne-Dawly rats, randomly assigned in two equal groups. Procedures- Under general anesthesia, and following surgical preparation, two uniform skin defects were made by 7mm skin punch. The water soluble extract was then applied on half of the wo...
