Complete sequencing and characterization of equine aggrecan
Veterinary and Comparative Orthopaedics and Traumatology, 2015SummaryObjectives: To fully sequence and characterize equine aggrecan and confirm conservation of major aggrecanase, calpain and matrix metalloproteinase (MMP) cleavage sites.Methods: Reverse transcription-polymerase chain reaction and rapid amplification of cDNA ends were used to generate clones that encompassed the complete equine aggrecan sequence ...

Mechanism of catabolism of aggrecan by articular cartilage
Archives of Biochemistry and Biophysics, 1992Characterization of aggrecan core protein peptides appearing in the medium of adult articular cartilage maintained in tissue culture showed that eight major peptides could be detected. The two largest peptides had the same N-terminal sequence as bovine aggrecan core protein and probably represent partly degraded aggrecan lost to the medium in the form ...

Perspectives on developmental neurobiology, 1997
During development, the extracellular matrix (ECM) is a complex dynamic structure whose components and organization help to establish the requisite position and state of differentiation. Until recently, the large chondroitin sulfate proteoglycan, aggrecan, has been localized predominantly to skeletal tissue and considered a hallmark of cartilage ...

Aggrecan, aging and assembly in articular cartilage
Cellular and Molecular Life Sciences, 2005The primary function of articular cartilage to act as a self-renewing, low frictional material that can distribute load efficiently at joints is critically dependent upon the composition and organisation of the extracellular matrix. Aggrecan is a major component of the extracellular matrix, forming high molecular weight aggregates necessary for the ...

Biorheology: The Official Journal of the International Society of Biorheology, 2004
We determined elasticity (G′) and viscosity (G″) of various aggrecan–hyaluronan solutions using a controlled‐stress rheometer with high (10 Hz) to low (0.1 Hz) frequencies. Aggrecan solution (50 mg/ml) alone showed little elasticity at any frequency, but the addition of 3300 kDa hyaluronan at 0.001–0.1 mg/ml markedly increased the elasticity, but not ...

Hyaluronan (HA) is a high molecular weight (105-107Da) unbranched glycosaminoglycan, composed of repeating disaccharides of D-N-Acetylglucosamine and D-Glucuronic acid. It is a widely distributed component of the extracellular matrix of vertebrate tissues [1].

Changes in aggrecan populations in experimental osteoarthritis
Osteoarthritis and Cartilage, 1994Adult articular cartilage contains at least two distinct populations of aggrecan: one is larger and richer in chondroitin sulfate (CS), while the other is smaller with less CS. The smaller form is thought to be derived from the larger. The amount of CS in cartilage decreases with maturation and aging, mainly because of a decrease in the proportion of ...

Agents and Actions, 1993
Bovine nasal septum aggrecan and selected proteinase-digested products of aggrecan were evaluated in an inhibition ELISA using the anti-keratan sulfate (KS) monoclonal antibody 5-D-4 (5D4). Undegraded aggrecan was recognized with an IC50 of 0.27 microgram/ml.

Analysis of Aggrecan Catabolism by Immunoblotting and Immunohistochemistry
2011Aggrecan is essential for the normal function of articular cartilage and intervertebral disc, where it provides the ability for the tissues to withstand compressive loading. This property depends on both the high charge density endowed by its numerous chondroitin sulfate and keratan sulfate chains and its ability to form large molecular aggregates via ...
