[ 1 ] - Immunolocalization of Galectin-3 in Mouse Testicular Tissue
Objective(s) Galectin-3 (Gal-3) is a member of the B-galactoside-binding lectins which is expressed in a variety of tissues and plays a role in diverse biological events, such as embryogenesis, adhesion, cellular proliferation, and apoptosis. In this study, the presence and distribution of galectin-3 (Gal-3) in the mouse testicular tissue was investigated. Materials and Methods Eight adult N...
[ 2 ] - Evaluation of CD98 Expression in Normal and Osteoarthritic Human Articular Chondrocytes
Background: Recent studies have provided evidence that integrins play roles in recognition of mechanical stimuli and its translation into a cellular response. Integrin signaling may be regulated by a number of mechanisms including accessory proteins such as CD98 (4F2 antigen). Objectives: To determine CD98 expression by human articular chondrocytes and its involvement in human articular mechano...
[ 3 ] - Differential Immunohistochemical Expression Pattern of Galectin-3 in Normal and Osteoarthritic Human Articular Cartilage
Background: Previous studies have shown that Galectin-3, a member of lectin family, is expressed in developing cartilage in mouse embryo and also in growth plate of long bones. Objective: In the present work, the expression pattern of Galectin-3 in normal and various grades of osteoarthritic (OA) human articular cartilage has been studied. Methods: Using immunohistochemistry and standard we...
[ 4 ] - Anticancer Activity of Curcumin-Loaded PLGA Nanoparticles on PC3 Prostate Cancer Cells
Curcumin (Cur) has been found to be very efficacious against many different types of cancercells. However, the major disadvantage associated with the use of Cur is its low systemicbioavailability. Our present work investigated the toxic effect of encapsulation of Cur in PLGA(poly lactic-coglycolic acid) nanospheres (NCur) on PC3 human cancer prostate cell. In thepresent study, we have investiga...
[ 5 ] - Curcumin-loaded poly lactic-co-glycolic acid nanoparticles effects on mono-iodoacetate -induced osteoarthritis in rats
Curcumin has been found to be very efficacious against many different types of diseases. However, the major disadvantage associated with the use of curcumin is its low systemic bioavailability. In the present study the protective effects of curcumin-loaded poly lactic-co-glycolic acid nanoparticles (nanocurcumin) against mono-iodoacetate-induced osteoarthritis in rats was inves...

[ 7 ] - Protective Effects of Interleukin-4 on Tissue Destruction and Morphological Changes of Bovine Nasal Chondrocytes in vitro
Background: Previous studies have shown that some cytokines have protective effects on cartilage in joint diseases. In the current study, effects of IL-4 against morphological changes and tissue degradation induced by IL-1α on bovine nasal cartilage (BNC) explants were investigated. Methods: Fresh BNC samples were prepared from a slaughterhouse under sterile conditions. BNC explants culture was...
[ 8 ] - Combination Effects of Prednisolone and Interleukin-4 Protect Bovine Nasal Cartilage Explants from Interleukin-1α Induced Degradation
Background: Current treatments for joint diseases are moderately successful, but unfortunately are associated with significant side effects. This study was undertaken to investigate the combination effects of IL-4 and prednisolone on tissue characteristics and production of matrix metalloproteinase-1(MMP-1) in IL-lα-treated bovine nasal cartilage (BNC) explants. Methods: BNC explants were cultu...
[ 9 ] - CD147 (Extracellular Matrix Metalloproteinase Inducer-EMMPRIN) Expression by Human Articular Chondrocytes
Background: Integrins are a family of transmembrane proteins that allow communication between the extracellular matrix and the interior of cells. Chondrocytes, cells of articular cartilage, express integrins and these molecules appear to have a variety of roles including mechanotransduction. Integrins are known to associate with a number of accessory molecules such as CD147 that may act to regu...
[ 10 ] - The Expression of Signal Regulatory Protein-alpha in Normal and Osteoarthritic Human Articular Cartilage and Its Involvement in Chondrocyte Mechano-transduction Response
Signal regulatory proteins (SIRP) belong to immunoglobulin super family (IgSF) and relate to integrin signaling cascades. It has been shown that SIRPa is expressed in a variety of cells including myeloid cells and neurons. In the present study the expression of this IgSF member in articular chondrocytes was investigated. Methods: Using a panel of anti-SIRPalpha antibodies, immunohistochemistry...
