Glomerulonephritis is an inflammation of the kidney characterized by the accumulation of extracellular matrix within the damaged glomeruli, impaired filtration and proteinuria. In its progressive form, the disease destroys kidney function leading to uraemia and death, unless dialysis therapy or kidney transplantation is available. The pathogenesis ...
Affinity chromatography was used to identify a putative cell surface receptor for fibronectin. A large cell-attachment-promoting fibronectin fragment was used as the affinity matrix, and specific elution was effected by using synthetic peptides containing the sequence Arg-Gly-Asp, which is derived from the cell recognition sequence in the fibronect...
The extracellular matrix of the adult brain tissue has a unique composition. The striking feature of this matrix is the prominence of lecticans, proteoglycans that contain a lectin domain and a hyaluronic acid-binding domain. Hyaluronic acid and tenascin family adhesive/anti-adhesive proteins are also abundant. Matrix proteins common in other tissu...
The lecticans are a family of chondroitin sulfate proteoglycans including aggrecan, versican, neurocan, and brevican. The C-terminal globular domains of lecticans are structurally related to selectins, consisting of a C-type lectin domain flanked by epidermal growth factor and complement regulatory protein domains. The C-type lectin domain of versi...
We report the identification and DNA sequence of a chondroitin sulfate proteoglycan core protein cDNA. A cDNA clone, pPG1, was selected from a rat yolk sac tumor poly(A)+RNA-derived cDNA library by using synthetic oligonucleotides predicted from the NH2-terminal peptide sequence of the mature chondroitin sulfate proteoglycan. The resulting sequence...
Tumour blood vessels express markers that are not present in resting blood vessels of normal tissues, but that can be shared by angiogenic vessels in non-malignant conditions. Many of these proteins are functionally important in the angiogenic process. Some tumours also contain lymphatic vessels, as well as channels that consist of cancer cells and...
