AIM Drug-eluting stents are widely used to prevent restenosis but are associated with late endothelial damage. To understand the basis for this effect, we have studied the consequences of a prolonged incubation with rapamycin on the viability and functions of endothelial cells. METHODS AND RESULTS Human umbilical vein or aorta endothelial cells were(More)
Decreased bone formation contributes to the development of bone lesions in multiple myeloma (MM) patients. In this study, we have investigated the effects of myeloma cells on osteoblast formation and differentiation and the potential role of the critical osteoblast transcription factor RUNX2/CBFA1 (Runt-related transcription factor 2/core-binding factor(More)
The proteasome inhibitor bortezomib may increase osteoblast-related markers in multiple myeloma (MM) patients; however, its potential osteoblastic stimulatory effect is not known. In this study, we show that bortezomib significantly induced a stimulatory effect on osteoblast markers in human mesenchymal cells without affecting the number of osteoblast(More)
The expression of the chemokine CC-chemokine ligand 20 (CCL20)/macrophage inflammatory protein (MIP)-3alpha and its receptor CC-chemokine receptor 6 (CCR6) by multiple myeloma (MM) and microenvironment cells and their potential relationship with osteoclast (OC) formation and osteolytic bone lesions in MM patients was investigated in this study. First, we(More)
BACKGROUND Evidence suggests that the PPARγ-agonist insulin sensitizer pioglitazone, may provide potential beneficial cardiovascular (CV) effects beyond its anti-hyperglycaemic function. A reduced endothelial progenitor cell (EPC) number is associated with impaired glucose tolerance (IGT) or diabetes, conditions characterised by increased CV risk. AIM To(More)
Multiple myeloma (MM) has the highest incidence of bone involvement amongst malignant diseases (1). Myeloma bone disease (MMBD) is characterized by osteoclast (OCL) activation with suppressed or absent osteoblast (OBL) function resulting in local bone destruction without new bone formation (2). IL-3 is a bifunctional cytokine that is upregulated in MM(More)
Basic fibroblast growth factor (bFGF) is a growth factor with proangiogenetic properties. Elevated bone marrow (BM) and peripheral serum bFGF levels have been reported in patients with multiple myeloma (MM) 1-3 ; however, the source of bFGF in patients with MM is not completely elucidated. Recently, Bisping et al, 4 in line with others, 1 have reported that(More)
Most of the information about the genetic composition of parathyroid tumors has been obtained by comparative genomic hybridization (CGH) and loss of heterozygosity (LOH) studies, whereas only few conventional cytogenetic investigation results are available. We have performed cytogenetic analysis of short-term cultures from 3 parathyroid adenoma tissue(More)
