13. Importance of hyaluronan biosynthesis and degradation in cell differentiation and tumor formation
Hyaluronan is an important connective tissue glycosaminoglycan. Elevated hyaluronan biosynthesis is a common feature during tissue remodeling under both physiological and pathological conditions. Through its interactions with hyaladherins, hyaluronan affects several cellular functions such as cell migration and differentiation. The activities of hyaluronan-s

14. Distribution of versican and hyaluronan in the mouse uterus during decidualization
Preparation for embryo implantation requires extensive adaptation of the uterine microenvironment. This process consists of cell proliferation and cell differentiation resulting in the transformation of endometrial fibroblasts into a new type of cell called decidual cell. In the present study, we followed the space-time distribution of versican and hyalurona

15. Proteoglicanos da cartilagem epifisaria de rãs : composição, estrutura e variações regionais
A large proteoglycan was isolated fTom the articular, lateral and growth regions of the femoral distal cartilage of the bullfTog, Rana catesbeiana, and identified as aggrecan by a series of biochemical and immunochemical assays. The isolated monomer showed a polydisperse behavior on Sepharose CL2B, with a peak at Kav= 0,17. This proteoglycan was shown to con

16. Assembly of pericellular matrices by COS-7 cells transfected with CD44 lymphocyte-homing receptor genes.
The capacity to assemble and retain a pericellular matrix is correlated with the expression of the cell surface binding sites specific for the extracellular matrix macromolecule hyaluronan. These binding proteins have been termed hyaluronan receptors. The lymphocyte-homing receptor CD44 may have identity with these hyaluronan receptors. To determine whether

17. Modulation of TGFβ1-Dependent Myofibroblast Differentiation by Hyaluronan
Myofibroblasts are contractile cells that are characterized by the expression of α-smooth muscle actin and mediate the closure of wounds and the formation of collagen-rich scars. Their presence in organs such as lungs, liver, and kidney has long been established as a marker of progressive fibrosis. The transforming growth factor beta1-driven differentiation

18. Effect of intra-articular hyaluronan on pressure-flow relation across synovium in anaesthetized rabbits.
1. Hyaluronan is the major polysaccharide of synovial fluid, responsible for its high viscosity. The effect of hyaluronan on fluid transport across the synovial lining of the joint was investigated. Rate of fluid absorption from the joint cavity (Qs) was measured at intra-articular pressures (Pj) of up to 24 cmH2O in knees of anaesthetized rabbits, in the pr

19. Organization of Hyaluronan and Versican in the Extracellular Matrix of Human Fibroblasts Treated With the Viral Mimetic Poly I:C
We have examined structural details of hyaluronan- and versican-rich pericellular matrices in human lung fibroblasts, as well as fixation effects after treatment with the viral mimetic, poly I:C. Lateral aggregation of hyaluronan chains was promoted by acid-ethanol-formalin fixation compared with a network appearance with formalin alone. However, hyaluronida

20. NLRP3/Cryopyrin Is Necessary for Interleukin-1β (IL-1β) Release in Response to Hyaluronan, an Endogenous Trigger of Inflammation in Response to Injury*S⃞
Inflammation under sterile conditions is a key event in autoimmunity and following trauma. Hyaluronan, a glycosaminoglycan released from the extracellular matrix after injury, acts as an endogenous signal of trauma and can trigger chemokine release in injured tissue. Here, we investigated whether NLRP3/cryopyrin, a component of the inflammasome, particip

21. The formation of human synovial joint cavities: a possible role for hyaluronan and CD44 in altered interzone cohesion.
During fetal development, cavitation occurs within the primitive skeleton along planes destined to become the articular surfaces of synovial joints. A histochemical study of human fetal limbs was undertaken to identify the cell types involved in this cavitation and the possible role of interactions between cells and extracellular matrix. Cryostat sections we

22. Delivery of CD44 shRNA/Nanoparticles within Cancer Cells: PERTURBATION OF HYALURONAN/CD44v6 INTERACTIONS AND REDUCTION IN ADENOMA GROWTH IN Apc Min/+ MICE*
Our studies have shown that constitutive interactions between hyaluronan and CD44 on tumor cells induces various anti-apoptotic cell survival pathways through the formation of a multimeric signaling complex that contains activated receptor tyrosine kinases. Inhibition of the hyaluronan-CD44 interactions on tumor cells by hyaluronan-CD44 interaction antag

23. Abnormal accumulation of hyaluronan matrix diminishes contact inhibition of cell growth and promotes cell migration
Elevated hyaluronan biosynthesis and matrix deposition correlates with cell proliferation and migration. We ectopically expressed three isoforms of hyaluronan synthase (HAS1, HAS2, or HAS3) in nontransformed rat 3Y1 cells and observed a de novo, massive formation of a hyaluronan matrix that resulted in a partial loss of contact-mediated inhibition of cell gr

24. Hyaluronan and type III procollagen peptide concentrations in bronchoalveolar lavage fluid in idiopathic pulmonary fibrosis.
The connective tissue components hyaluronan (hyaluronic acid) and type III procollagen peptide were measured in bronchoalveolar lavage fluid in 22 patients with idiopathic pulmonary fibrosis and 21 healthy control subjects. The patients with idiopathic pulmonary fibrosis had higher concentrations of hyaluronan (median 46 micrograms/l) and type III procollage
