Lysyl oxidase (LOX) catalyzes cross-linking of elastin and collagen, which is essential for structural integrity and function of bone tissue. The present study examined the role of Lox gene deficiency for the osteoblast phenotype in primary calvarial osteoblasts from E18.5 Lox knockout (Lox-/-) and wild type (wt) (C57 BL/6) mice. Next to Lox gene depletion, mRNA expression of Lox isoforms, LOXL1-4, was significantly down-regulated in Lox-/- bone tissue. A significant decrease of DNA synthesis of Lox-/- osteoblasts compared to wt was found. Early stages of osteoblastic apoptosis studied by Annexin-V binding as well as later stages of DNA fragmentation were not affected. However, mineral nodule formation and osteoblastic differentiation were markedly decreased, as revealed by significant down-regulation of osteoblastic markers, type I collagen, BSP and Runx2/Cbfa1.
