Web24 apr. 2024 · Our data suggest that down-regulation by LECs may be another important mechanism. While ELN is down-regulated in hypoxic LECs, the enzyme responsible for crosslinking of lysine residues in ELN, lysyl-oxidase (LOX), is upregulated and may then induce more efficient cross-linking of collagen fibrils.
Web30 apr. 2024 · Introduction. The lysyl oxidase family (LOX; also termed as protein-lysine 6-oxidase) has been traditionally defined as cuproenzymes that are essential for stabilization of extracellular matrix (ECM), particularly cross-linking of collagen and elastin (Rucker et al., 1998; Kagan and Li, 2003).LOX mainly comprises of five members that were originally …
