Collagen V is a minor component of the heterotypic I/III/V collagen fibrils and the defective product in most cases of classical Ehlers Danlos syndrome (EDS). The present study was undertaken to elucidate the impact of collagen V mutations on skin development, the most severely affected EDS tissues, using mice harboring a targeted deletion of the alpha2(V)(More)
The expression of the protein DCC (deleted in colorectal cancer) is lost or markedly reduced in numerous cancers and in the majority of colorectal cancers due to loss of heterozygosity in chromosome 18q, and has therefore been proposed to be a tumour suppressor. However, the rarity of mutations found in DCC, the lack of cancer predisposition of DCC mutant(More)
The predominant form of type V collagen is the [α1(V)]₂α2(V) heterotrimer. Mutations in COL5A1 or COL5A2, encoding respectively the α1(V)- and α2(V)-collagen chain, cause classic EDS (Ehlers-Danlos syndrome), a heritable connective tissue disorder, characterized by fragile hyperextensible skin and joint hypermobility. Approximately half of the classic EDS(More)
Soft connective tissues such as skin, tendon or cornea are made of about 90% of extracellular matrix proteins, fibrillar collagens being the major components. Decreased or aberrant collagen synthesis generally results in defective tissue mechanical properties as the classic form of Elhers-Danlos syndrome (cEDS). This connective tissue disorder is caused by(More)
The specific interaction of the upstream element-containing promoter of the Escherichia coli acetate operon with either the RNA polymerase holoenzyme or its alpha subunit has been analyzed by the base removal method. Our results indicate that: (i) direct and specific base contacts can be detected in the acetate promoter-alpha subunit complex; (ii) base(More)
Collagen V, a fibrillar collagen with important functions in tissues, assembles into distinct chain associations. The most abundant and ubiquitous molecular form is the heterotrimer [α1(V)] 2 α2(V). In the attempt to produce high levels of recombinant collagen V heterotrimer for biomedical device uses, and to identify key factors that drive heterotrimeric(More)
