Type I collagen synthesis follows translation in the … WebCollagen synthesis is a multistep process involving many organelles of the cell. Regulation of collagen synthesis is based on cell type but other factors such as cytokines, TGF-β, fibroblast-growth-factors, and insulin-like-growth-factors also control synthesis. Alternative splicing has been reported for various types of collagen possibly ...

WebEffect of vitamin C and its derivatives on collagen synthesis and cross-linking by normal human fibroblasts Vitamin C (VitC) plays a critical role in the maintenance of a normal mature collagen network in humans (anti-scurvy properties) by preventing the auto-inactivation of lysyl and prolyl hyroxylase, two key enzymes in collagen biosynthesis. WebJan 1, 2010 · IGF-I is known to induce collagen synthesis in animal tendon explants (Abrahamsson et al. 1991; Banes et al. 1995; Murphy & Nixon, 1997), and in mice that over …
WebType I collagen is synthesized as a procollagen precursor, which consists of an N-terminal propeptide, central collagen domain and C-terminal propeptide. Procollagen chains are cotranslationally translocated into the lumen of rough endoplasmic reticulum (ER). First, a three-dimensional stranded structure is assembled, with the amino acids glycine and proline as its principal components. This is not yet collagen but its precursor, procollagen. Procollagen is then modified by the addition of hydroxyl groups to the amino acids proline and lysine. This step is important for later glycosylation and the formation of the triple helix structure of collagen. Because the hydroxylase enzymes that perform these reactions require vitamin C as a c…
