Iron mobilization from ultraviolet-irradiated, iron-saturated, transferrin
Autor: Josiane Haigle, Patrice Morlière, M. Aubailly, René Santus, S. Salmon
Publikováno v: Redox report : communications in free radical research. 2(1)
Transferrin is the major iron transport protein of mammalian plasma. The ultraviolet-B irradiation of 1.4 mg/ml iron saturated transferrin solutions (~32 μM Fe(3+)) induces a Fe(3+) loss accompanied by Fe(2+) formation. The initial quantum yield of

The potential protective effects of the flavanol catechin, the flavonol quercetin, the flavones, luteolin and rutin, and the isoflavones, genistein and daidzein, against the photo-oxidative stress induced by ultraviolet A radiation (UVA) and by photo

Anti- and pro-oxidant effects of quercetin in copper-induced low density lipoprotein oxidation. Quercetin as an effective antioxidant against pro-oxidant effects of urate

We recently reported that, depending on its concentration, urate is either a pro- or an antioxidant in Cu(2+)-induced low-density lipoprotein (LDL) oxidation. We also previously demonstrated an antioxidant synergy between urate and some flavonoids in

Anti- and pro-oxidant effects of urate in copper-induced low-density lipoprotein oxidation

Publikováno v: European Journal of Biochemistry. 269:5474-5483
We reported earlier that urate may behave as a pro-oxidant in Cu2+-induced oxidation of diluted plasma. Thus, its effect on Cu2+-induced oxidation of isolated low-density lipoprotein (LDL) was investigated by monitoring the formation of malondialdehy

Comparative effects of nacre water-soluble matrix and dexamethasone on the alkaline phosphatase activity of MRC-5 fibroblasts
Autor: Josiane Haigle, Evelyne Lopez, Maria Almeida, Lucilia Pereira, Mário A. Barbosa, Christian Milet
Publikováno v: Journal of Biomedical Materials Research. 57:306-312
In this study we demonstrate, for the first time, that dexamethasone and BMP-2 stimulated alkaline phosphatase (ALP) activity in MRC-5 fibroblasts, a cell line derived from human fetal lung. Previously we reported that the water-soluble matrix (WSM)

UV photolysis of catalase revisited: a spectral study of photolytic intermediates
Autor: Josiane Haigle, M. Aubailly, Anne Giordani, René Santus, Patrice Morlière
Publikováno v: Journal of Photochemistry and Photobiology B: Biology. 56:61-67
The 365-nm irradiation of 4.6 microM (approximately equal to 1.1 mg/ml) catalase solutions in pH 7.4 phosphate buffer induces spectral modifications. Difference spectra show maxima at 434, 555, 584 nm at the beginning of the irradiation, then a final

Copper- and malondialdehyde-induced modification of high density lipoprotein and parallel loss of lecithin cholesterol acyltransferase activation
Autor: Josiane Haigle, Isaac Myara, Martine Auclair, René Santus, Cécile Mazière, S. Salmon, Jean-Claude Mazière
Publikováno v: Atherosclerosis. 104:213-219
Incubation of high density lipoproteins (HDL) with 0.1–10 μM copper ions resulted in a decrease in tryptophan residues and a moderate diminution of lysine residues. Polymerization of apolipoprotein AI (apo A-I) was only observed for the highest co

STRUCTURES OF THE BERGAMOTTIN PHOTOPRODUCTS

Publikováno v: Photochemistry and Photobiology. 57:222-227
The extensive use of bergamot oil in perfumery and cosmetics led us to study the photoreactivity of 5-geranoxypsoralen (bergamottin), the major chromophore in this oil. Structure determination of the bergamottin photoproducts was achieved using exten
