1. "Estudo funcional do colágeno tipo XVIII" / Functional study of the type XVIII collagen
A síndrome de Knobloch (SK) é uma doença autossômica recessiva rara, caracterizada por problemas oculares e presença de encefalocele occipital, porém o quadro clínico é variável. Os pacientes apresentam principalmente miopia de grau elevado, degeneração vítreo-retiniana e descolamento de retina; o grau de comprometimento da alteração no occipit

2. Collagens and proteoglycans of the corneal extracellular matrix
The cornea is a curved and transparent structure that provides the initial focusing of a light image into the eye. It consists of a central stroma that constitutes 90% of the corneal depth, covered anteriorly with epithelium and posteriorly with endothelium. Its transparency is the result of the regular spacing of collagen fibers with remarkably uniform diam

3. Lack of collagen XVIII/endostatin results in eye abnormalities
Mice lacking collagen XVIII and its proteolytically derived product endostatin show delayed regression of blood vessels in the vitreous along the surface of the retina after birth and lack of or abnormal outgrowth of retinal vessels. This suggests that collagen XVIII/endostatin is critical for normal blood vessel formation in the eye. All basement membrane

4. Alpha 1(XVIII), a collagen chain with frequent interruptions in the collagenous sequence, a distinct tissue distribution, and homology with type XV collagen.
We report on the isolation of mouse cDNA clones which encode a collagenous sequence designated here as the alpha 1 chain of type XVIII collagen. The overlapping clones cover 2.8 kilobases and encode an open reading frame of 928 amino acid residues comprising a putative signal peptide of 25 residues, an amino-terminal noncollagenous domain of 301 residues, an

5. Human tumstatin and human endostatin exhibit distinct antiangiogenic activities mediated by αvβ3 and α5β1 integrins
Tumstatin and endostatin are two inhibitors of angiogenesis derived from precursor human collagen molecules known as α3 chain of type IV collagen and α1 chain of type XVIII collagen, respectively. Although both these inhibitors are noncollagenous (NC1) domain fragments of collagens, they only share a 14% amino acid homology. In the present study we evaluat
