Lysyl oxidase polymorphisms and susceptibility to osteosarcoma.

ABSTRACT: Despite the knowledge of many genetic alterations present in osteosarcoma, the complexity of this disease precludes placing its biology into a simple conceptual framework. Lysyl oxidase (LOX) catalyzes the cross-linking of elastin and collagen, which is essential for the structural integrity and function of bone tissue. In the current study, we performed genomic sequencing on all seven exons--including the intron-exon splice sites, and the putative promoter region of LOX gene--followed by luciferase reporter assay to analyze the function of newly identified polymorphisms. Associations between LOX polymorphisms and osteosarcoma were then evaluated. Our sequencing data revealed three polymorphisms (-22G/C, 225C/G, and 473G/A) in the exons and promoter region of LOX. The -22G/C polymorphism l
