The aim of this study was to assess the integrity and kidney overall functional capacity subjects exposed landfill emissions. Urine blood levels Pb Cd, several newly biomarkers nephrotoxicity (Kim Injury Molecule 1 (KIM-1), alpha-1 Microglobulin (α1 M), beta-2 (β2 Cystatin-C (Cyst C), Clusterin, alpha-glutathione S-transferase (GSTα), pi-glutathione (GSTπ), Tissue Inhibitor Metalloproteinase-1 ...

BACKGROUND Hypertensive patients develop carotid atherosclerotic plaques with enhanced inflammation. Full-length osteopontin (OPN-FL), a multifunctional protein whose levels are elevated in association with atherosclerosis, is cleaved by thrombin and matrix metalloproteinases to form a C-terminal and a putatively biologically active N-terminal fragment (OPN-C, OPN-N, respectively). We conducted...

BACKGROUND Osteopontin (OPN) is a multifunctional cytokine involved in cell survival, migration, and adhesion. However, its role in chemosensitivity in locally advanced oral squamous cell carcinoma (OSCC) in humans has not yet been investigated. METHODS We enrolled 121 patients with locally advanced stage IVA/B OSCC receiving cisplatin-based IC followed by CCRT from January 1, 2006, through J...

We have studied the effect of chitosan sponges, produced from batches with distinct degree deacetylation (DDA) and molecular weight (Mw), on adhesion, growth differentiation primary human osteoblasts an aim to offer a suitable tool for guided bone regeneration. All sponges revealed similar microstructure, irrespective DDA (58, 73, 82, 88, 91 %) Mw (749, 547, 263, 215, 170 kDa, respectively). Ce...

BACKGROUND Osteopontin (OPN) is a plasma protein/cytokine produced in excess in several malignancies. In a recent study OPN was reported as being related to the duration of asbestos exposure and presence of benign asbestos-related diseases; however, it was unclear whether this protein was an indicator of exposure or effect. METHODS In 193 workers, 50 with pleural plaques (PP), in whom differe...

The expression of osteopontin (OPN) in boar testis was studied. Western blot analysis detected 66- and 32-kDa OPN immunopositive bands in the testes of adult boars. In postnatal piglets, the 66-kDa OPN band was detected in the testes, but not the 32-kDa band. In the newborn testis, OPN immunostaining was seen in gonocytes and in some supporting cells in the seminiferous tubules, as well as in i...

PURPOSE To investigate the effects of loss of osteopontin (OPN) in the development of neovascularization in corneal stroma in mice. Cell culture study was also conducted to clarify the effects of OPN in transforming growth factor (TGF) beta1-driven cell signaling and expression of vascular endothelial growth factor (VEGF). METHODS Ocular fibroblasts from wild-type and OPN-null mice were used ...

Purpose Osteopontin (OPN) is a secreted phosphoprotein functioning in monocyte and T cell adhesion and migration. Expression of OPN in alternatively-activated macrophages has been implicated in post-inflammatory fibrosis of lung and kidney. In our previously conducted cross-sectional study of 72 pediatric SLE patients (pSLE; age of onset <18 years), increased circulating plasma OPN (cOPN) was o...

Osteopontin (OPN) is involved in a variety of biological processes, including bone remodeling, innate immunity, acute and chronic inflammation, and cancer. The expression of OPN occurs in various tissues and cells, including intestinal epithelial cells and immune cells such as macrophages, dendritic cells, and T lymphocytes. OPN plays an important role in the efficient development of T helper 1...

Osteopontin (opn) is a glyco-phosphoprotein that is expressed and secreted by numerous human cancers. Opn has pivotal role in cell adhesion, chemotaxis, prevention of apoptosis, invasion, migration and anchorage-independent growth of tumor cells. Extensive research has demonstrated the pivotal role of opn in regulation of cellular signaling, which controls neoplastic and malignant transformatio...
