We have worked out a simplification of the procedure described by Schmitz et al. (Biochim. Biophys. Acta (1973) 323, 98--112) for the preparation of brush border membranes from small intestine. The procedure ultimately adopted is simple, rapid, does not necessarily require scraping and can be started from fresh or frozen material. It can be scaled up(More)
OBJECTIVE Epidemiology suggests that Mediterranean diets are associated with reduced risk of cardiovascular disease. Because monocyte adhesion to the endothelium is crucial in early atherogenesis, we evaluated whether typical olive oil and red wine polyphenols affect endothelial-leukocyte adhesion molecule expression and monocyte adhesion. METHODS AND(More)
Physiological mechanisms of gastrointestinal absorption of organic solutes among crustaceans remain severely underinvestigated, in spite of the considerable relevance of characterizing the routes of nutrient absorption for both nutritional purposes and formulation of balanced diets in aquaculture. Several lines of evidence attribute a primary absorptive(More)
We report the molecular and functional characterisation of a novel peptide transporter from zebrafish, orthologue to mammalian and avian PEPT1. Zebrafish PEPT1 is a low-affinity/high-capacity system. However, in contrast to higher vertebrate counterparts in which maximal transport activity is independent of extracellular pH, zebrafish PEPT1 maximal(More)
Angiotensin II (Ang II) induces, through AT1, intracellular Ca(2+) increase in both normal and cancerous breast cells in primary culture (Greco et al., 2002 Cell Calcium 2:1-10). We here show that Ang II stimulated, in a dose-dependent manner, the 24 h-proliferation of breast cancer cells in primary culture, induced translocation of protein kinase C(More)
AIMS Cyclooxygenase (COX)-2 expression is increased in inflammation and angiogenesis and also in atherosclerotic plaques, where it co-localizes with metalloproteinases (MMPs) involved in the fibrous cap weakening. Insight into the regulation of COX-2 and MMP-9 expression suggests the involvement of a Rho-dependent pathway. Because statins interfere with Rho(More)
Diets with high content of antioxidant polyphenols are associated with low prevalence of cardiovascular diseases and cancer. Inflammatory angiogenesis is a key pathogenic process both in cancer and atherosclerosis, and is tightly regulated by the proinflammatory enzyme cyclooxygenase (COX)-2 and the matrix degrading enzymes matrix metalloproteinases (MMPs).(More)
Carcinoma progression is associated with the loss of epithelial features, and the acquisition of a mesenchymal phenotype by tumour cells. Herein we show that exposure of MCF-7 cells to epidermal growth factor (EGF) resulted in morphological alterations characteristic of epithelial-to-mesenchymal transition (EMT). EGF treatment resulted in increased motility(More)
In this paper the signal transduction pathways evoked by bradykinin (BK) in MCF-7 breast cancer cells were investigated. BK activation of the B(2) receptor provoked: (a) the phosphorylation of the extracellular signal-regulated kinases 1 and 2 (ERK1/2); (b) the translocation from the cytosol to the membrane of the conventional protein kinase C-alpha(More)
We developed a novel filtration-based method that can eliminate dead or severely damaged Salmonella enterica and Listeria monocytogenes in food samples. This new method can recover all viable bacteria in less than 30 min, and can be coupled with a subsequent bacterial DNA extraction and real-time PCR. No statically significant differences (p<0.01) were(More)
