Breast cancer is the most common cancer in women in industrialized countries. Environmental factors, such as differences in diet are likely to have an important influence on cancer emergence. Among these factors, n-3 polyunsaturated-fatty acids, such as docosahexaenoic acid (DHA), are good candidates for preventing breast cancer. Here we investigate the(More)
We performed a saturation binding study with 125I-labeled FGF (fibroblast growth factor)-2 in a nonselected series of 250 human primary breast cancers. Two hundred twenty-five breast cancer biopsies possessed bFGFR (basic FGF receptor). The median dissociation constant was 0.35 nM (range, 0.014-1.9), and the median concentration was 1126 fmol/mg protein(More)
Previously, a proteinacious factor secreted by a mixture of rat testicular spermatocytes and round spermatids was shown to stimulate transferrin mRNA and protein levels in Sertoli cells. To identify the germ cell-secreted proteins which affect Sertoli cell functions, concentrated germ cell-conditioned medium was fractionated by reverse-phase HPLC. The(More)
For several years, lipids and especially n - 3 and n - 6 polyunsaturated fatty acids (PUFAs) receive much attention in human health. Epidemiological studies tend to correlate a PUFA-rich diet with a reduced incidence of cancer, including breast cancer. However, the molecular and cellular mechanisms supporting the effect of PUFAs in breast cancer cells(More)
Low levels of tyrosine and phenylalanine alter the metastatic phenotype of B16BL6 murine melanoma. In this study, we investigated expression and secretion of fibroblast growth factor-like (FGF-like) and transforming growth factor beta-like (TGF beta-like) molecules as well as the biological effect of basic FGF (bFGF) and TGF beta 1 on high (NDP) and low(More)
Polypeptide growth factors mediate their cellular responses by binding to and activating specific cell surface receptors. Monoclonal antibody (MAb) VBS-1, produced against native fibroblast growth factor receptor-1 (FGFR-1), inhibited the binding of fibroblast growth factor-2 (FGF-2) to its receptor on coronary venular endothelial cells (CVECs) as(More)
Monoclonal antibodies against the high affinity tyrosine kinase Fibroblast Growth Factor (FGF) receptor may help define receptor epitopes involved in FGF binding and signal transduction which mediate coronary and tumor angiogenesis (the development of blood vessels). Monoclonal antibodies against the FGF receptor were made by in vitro immunization. Receptor(More)
In breast cancer cells, the neurotrophin receptor p75(NTR) acts as a prosurvival factor able to stimulate resistance to apoptosis, but its mechanism of action remains incompletely defined. In this study, we investigated the global proteome modification induced by p75(NTR) overexpression in breast cancer cells treated by the pro-apoptotic agent tumor(More)
Spores are dormant units of bacteria resistant to numerous disinfection methods. Additionally, the effects on bacteria of repetitive electrical discharges in water by used of the so-called "corona discharges" or streamer are poorly described. In this study vegetative and spore forms of Bacillus subtilis var. niger were subjected to these discharges. To(More)
The rise of human populations and the growth of cities contribute to the depletion of natural resources, increase their cost, and create potential climatic changes. To overcome difficulties in supplying populations and reducing the resource cost, a search for alternative pharmaceutical, nanotechnology, and energy sources has begun. Among the alternative(More)
