| selective cytotoxicity evaluation in anticancer drug screening of fractionated plant extracts. | chosen to reflect biodiversity in a phylogenetic sense, 100 fractionated plant extracts were screened in vitro for cytotoxicity following extraction and fractionation (polypeptide isolation). of these 100 extracts, 30 were selected and then characterized preliminarily for antitumor potency and mode of action by testing them on two cell lines and primary cultures of human tumor cells. on the basis of cytotoxicity potency, 10 of the extracts were further characterized for anticancer activity in 10 ... | 2002 | 12230887 |
| cvadh1, a member of short-chain alcohol dehydrogenase family, is inducible by gibberellin and sucrose in developing watermelon seeds. | to understand the molecular mechanisms that control seed formation, we selected a seed-preferential gene (cvadh1) from the ests of developing watermelon seeds. rna blot analysis and in situ localization showed that cvadh1 was preferentially expressed in the nucellar tissue. the cvadh1 protein shared about 50% homology with short-chain alcohol dehydrogenase including aba2 in arabidopsis thaliana, stem secoisolariciresinol dehydrogenase in forsythia intermedia, and 3beta-hydroxysterol dehydrogenas ... | 2003 | 12552151 |
| systemic induction of the biosynthesis of terpenic compounds in digitalis lanata. | a bacterial screening was carried out in the rhizosphere of two digitalis species, d. thapsi and d. parviflora, both at the vegetative stage and at flowering. a total of 480 isolates were characterised at genus level, bacillus being the dominant genera in all cases. fifty percent of the bacillus strains isolated from each species were analysed by pcr-rapds. at 85% similarity, 12 groups separated for d. thapsi and 18 for d. parviflora. one strain of each group was selected for biological assay on ... | 2003 | 12685026 |
