Melanoma inhibitory activity member 3 (MIA3/TANGO1) [corrected] is an evolutionarily conserved endoplasmic reticulum resident transmembrane protein. Recent in vitro studies have shown that it is required for the loading of collagen VII, but not collagen I, into COPII-coated transport vesicles. In this paper, we show that mice lacking Mia3 are defective for the secretion of numerous collagens, i...
Conditions were defined for promoting cell growth, hypertrophy, and extracellular matrix mineralization of a culture system derived from embryonic chick vertebral chondrocytes. Ascorbic acid supplementation by itself led to the hypertrophic phenotype as assessed by respective 10- and 15-fold increases in alkaline phosphatase enzyme activity and type X synthesis. Maximal extracellular matrix min...
CONTEXT Lumbar disk disease (LDD) is one of the most common musculoskeletal diseases, with a prevalence of about 5%. A tryptophan (Trp) allele (Trp2) was recently discovered in the COL9A2 gene that is associated with dominantly inherited LDD but is only present in about 4% of Finnish patients with LDD. OBJECTIVE To determine if other collagen IX gene sequence variations play a role in the pat...
The mechanism of chain selection and trimerization of fibril-associated collagens with interrupted triple helices (FACITs) differs from that of fibrillar collagens that have special C-propeptides. We recently showed that the second carboxyl-terminal non-collagenous domain (NC2) of homotrimeric collagen XIX forms a stable trimer and substantially stabilizes a collagen triple helix attached to ei...
BACKGROUND An increasing number of studies have investigated associations between collagen IX alpha 2 chain (COL9A2) and collagen IX alpha 3 chain (COL9A3) gene polymorphisms and the risk of lumbar disc degeneration (LDD). However, these studies have yielded contradictory results. The purpose of this meta-analysis is to investigate the association between the collagen IX gene polymorphisms (rs1...
Introduction Matrilin-3 is a member of the newly defined matrilin family of extracellular matrix proteins. All matrilin family members consist of one or two von Willebrand factor type A-like domain(s), 1-10 epidermal growth factor-like domain(s) and a C-terminal coiled-coil oligomerization domain (1). Matrilin-1 (also known as CMP) and matrilin-3 are prominent matrix components of growth cartil...
The frequencies of antibodies to the cartilage type IX and XI collagens and to type I collagen were determined in 188 patients with rheumatoid arthritis, of whom 76 were positive for antibodies to native type II collagen. A higher proportion of patients with antibodies to native type II collagen had antibodies to these other collagens, but about one third of patients without antibodies to nativ...
