BACKGROUND We investigated the extent, modalities and reversibility of changes at cellular level in the expression of genes and proteins occurring upon Hind limb unloading (HU) in the tibiae of young C57BL/6J male mice. We focused on the effects of HU in chondrogenic, osteogenic, and marrow mesenchymal cells. METHODS We analyzed for expression of genes(More)
Many patients affected by early onset familial Alzheimer's disease (FAD), carry mutations in the presenilin 1 (PS1) gene. Since it has been suggested that FAD-linked PS1 mutations impair the unfolded protein response (UPR) due to endoplasmic reticulum (ER) stress, we analyzed the UPR and amyloid beta-protein processing in fibroblasts bearing various PS1(More)
Fibrocytes are circulating, hematopoietic cells that express CD45 and Col1a1. They contribute to wound healing and several fibrosing disorders by mechanisms that are poorly understood. In this report, we demonstrate that fibrocytes predispose the lung to B16-F10 metastasis by recruiting Ly-6C(+) monocytes. To do so, we isolated fibrocytes expressing CD45,(More)
Proinflammatory components are present in abdominal aortic aneurysm (AAA). Circulating monocytes display heterogeneity, and three subsets have been identified, based on the differential expression for CD14 and CD16 receptors: CD14(+)CD16(−), classical, CD14(+)CD16(+), intermediate and CD14(dim)CD16(+), non-classical monocytes. Increased proinflammatory(More)
Apigenin is a naturally occurring plant flavone with strong anti-oxidant and anti-inflammatory activity. While the anticancer properties of Apigenin have been extensively studied, little is known about its effects on endothelial dysfunction. We investigated the effects of Apigenin in EAhy926 endothelial cells exposed to TNFα by evaluating the expression of(More)
OBJECTIVE The uremic toxin Indoxyl-3-sulphate (IS), a ligand of Aryl hydrocarbon Receptor (AhR), raises in blood during early renal dysfunction as a consequence of tubular damage, which may be present even when eGFR is normal or only moderately reduced, and promotes cardiovascular damage and monocyte-macrophage activation. We previously found that patients(More)
The cell adhesion molecule CD146 is normally located at the endothelial cell-to-cell junction and colocalizes with actin cytoskeleton. The soluble form of CD146 (sCD146) has been identified in the endothelial cell supernatant and in normal human plasma, and is increased in pathologic conditions with altered endothelial function. Soluble CD146 binding to(More)
The cyanobacterium Arthrospira platensis has been considered as a potential source of several therapeutic compounds including antioxidant molecules such as phenolics. Several studies have demonstrated that the exposure to a particular stress factor, such as UV-light, is able to modify the quality and the quantity of polyphenols produced by A. platensis. In(More)
BACKGROUND The COOH terminal peptide of Pro-collagen type I (PICP, also called C3) is chemotactic for endothelial melanoma and breast cancer cells. PICP induces the expression of Metalloproteinases-2 and -9, of Vascular endothelial growth factor and of the chemokine CXCL-12 receptor CXCR4 in MDA MB231 breast carcinoma cells in vitro. METHODS We used a(More)
