Tumor suppressive effect of lysyl oxidase proenzyme

Lysyl Oxidase and the Tumor Microenvironment

The lysyl oxidase (LOX) family of oxidases contains a group of extracellular copper-dependent enzymes that catalyze the cross-linking of collagen and elastin by oxidation, thus maintaining the rigidity and structural stability of the extracellular matrix (ECM). Aberrant expression or activation of LOX alters the cellular microenvironment, leading to many diseases, including atherosclerosis, tis...

Lysyl Oxidase-related Protein-1 Promotes Tumor Fibrosis

The lysyl oxidase gene family members function as extracellular matrix modulating enzymes. We have found that another member of this family, lysyl oxidase related protein-1 (LOR-1), is highly expressed in metastatic breast cancer-derived cell lines but not in the nonmetastatic estrogendependent MCF-7 cells. Furthermore, LOR-1 expression in periductal tumor cells of breast carcinomas is signific...

LOXL2 (lysyl oxidase-like 2)

The LOXL2 gene is located on chromosome 8p21.2p21.3 (Jourdan-Le Saux et al., 1998). It is composed of fourteen exons and thirteen introns, distributed through approximately 107 kb of genomic DNA (Fong et al., 2007). Two transcripts of sizes 3.6 kb and 4.9 kb have been reported, with the smaller transcript much more abundant and resulting from three possible termination sites located 690 bp, 740...

Regulation of lysyl oxidase in vascular cells: lysyl oxidase as a new player in cardiovascular diseases.

Lysyl oxidase (LOX) plays a crucial role in the maintenance of extracellular matrix stability and could participate in vascular remodelling associated with cardiovascular diseases. Evidence from in vitro and in vivo studies shows that LOX downregulation is associated with the endothelial dysfunction characteristic of earlier stages of the atherosclerotic process. Conversely, upregulation of thi...
