Description:
The development of osteoporosis involves the interaction of multiple environmental and genetic factors. Through combined genetic and genomic approaches, we identified the lipoxygenase gene Alox15 as a negative regulator of peak bone mineral density in mice. Crossbreeding experiments with Alox15 knockout mice confirmed that 12/15-lipoxygenase plays a role in skeletal development. Pharmacologic inhibitors of this enzyme improved bone density and strength in two rodent models of osteoporosis. These results suggest that drugs targeting the 12/15-lipoxygenase pathway merit investigation as a therapy for osteoporosis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Klein, Robert F -- Allard, John -- Avnur, Zafrira -- Nikolcheva, Tania -- Rotstein, David -- Carlos, Amy S -- Shea, Marie -- Waters, Ruth V -- Belknap, John K -- Peltz, Gary -- Orwoll, Eric S -- AR44659/AR/NIAMS NIH HHS/ -- HG02322/HG/NHGRI NIH HHS/ -- R01 AR044659/AR/NIAMS NIH HHS/ -- R01 AR044659-08/AR/NIAMS NIH HHS/ -- New York, N.Y. -- Science. 2004 Jan 9;303(5655):229-32.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Bone and Mineral Research Unit, Department of Medicine, School of Medicine, Oregon Health and Science University, 3181 Southwest Sam Jackson Park Road, Portland, OR 97239, USA. kleinro@ohsu.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/14716014" target="_blank"〉PubMed〈/a〉
