Cytokines play a major role in the initiation of the immune response or acute inflammatory events, and in the transition to or persistence of chronic inflammation, which eventually lead to tissue destruction and/or fibrosis. Cytokine inhibi...
Effects of hormones and local growth factors on articular chondrocyte metabolism [0.03%]

Human chondrocyte proliferation and production of matrix components such as proteoglycans and type II collagen (coll. II) were studied in an in vitro model of differentiated chondrocytes. It clearly appears that several hormones such as gro...

Studies of articular cartilage over the decades have demonstrated a surprisingly brisk rate of synthesis of the matrix proteins which appears to vary considerably with metabolic, physicochemical and pathological state of the tissue. It has ...
Changes in proteoglycans in osteoarthritis: biochemistry, ultrastructure and biosynthetic processing [0.03%]

The loss of proteoglycans from articular cartilage is a hallmark of the osteoarthritic process. Compensatory biosynthesis of proteoglycans is evident by histochemical analysis, characterized by significant metachromasy in the pericellular r...
Measurement of proteoglycan mRNA in articular cartilage--preliminary investigations [0.03%]

Measurement of mRNA in adult articular cartilage could define whether treatment with nonsteroidal antiinflammatory drugs affects the rate of proteoglycan synthesis in vivo in osteoarthritis. We studied a variety of extraction and isolation ...

Aging of human articular cartilage is associated with proteolytic degradation of its constituent proteoglycan aggregates. Similar events are thought to be associated with proteoglycan loss in osteoarthritis. Degradative changes in link prot...

The molecular sites of crosslinking between types II and IX collagens of bovine articular cartilage have been defined. All 3 chains of the type IX molecule, alpha 1 (IX), alpha 2 (IX) and alpha 3 (IX), contain an hydroxylysine close to the ...

The ability of articular cartilage to undergo reversible deformation is dependent upon the organization of specific macromolecules within the extracellular matrix. This abundant matrix is elaborated by a small number of chondrocytes which m...
Early bone changes in experimental osteoarthritis using microscopic computed tomography [0.03%]

Alterations in trabecular subchondral bone have been measured using a microscopic computed tomography scanner in the guinea pig hind-limb myectomy model of osteoarthritis. These bone changes can be found as early as histologic changes in ca...
Magnetic resonance imaging reflects the chemical changes of aging degeneration in the human intervertebral disk [0.03%]

T2 weighed spin echo magnetic resonance images (MRI) of the intervertebral disks of 4 lumbar spines were graded and the nuclei pulposi were analyzed for water, collagen and proteoglycan. The brightness of the nuclear image correlated direct...
