Variation of gene associated with decreased risk of heart attack and stroke

12.05.2004


Individuals who have a variation of the COX-2 gene have an associated lower risk for a heart attack or stroke, according to a study in the May 12 issue of The Journal of the American Medical Association (JAMA).

Although myocardial infarction (MI, or heart attack) and atherothrombotic ischemic stroke are thought to be caused by rupture of vulnerable atherosclerotic plaques, they are recognized to be complex disorders that likely result from multifaceted interactions between an individual’s genetic makeup and environmental factors, according to background information in the article. The relation between COX-2 variations and the risk of MI and stroke has not been clear.

Francesco Cipollone, M.D., of the G. d’Annunzio University of Chieti and G. d’Annunzio University Foundation, Chieti, Italy and colleagues conducted a study to determine if there was a relationship between a variation in the COX-2 gene (termed the "-765G-C polymorphism") and clinically evident plaque rupture. The study was conducted between March 2002 and October 2003 among 864 patients with first MI or atherothrombotic ischemic stroke and 864 hospitalized controls. The groups were matched for age, sex, body mass index, smoking, hypertension, hypercholesterolemia, and diabetes.



The researchers found that the prevalence of this specific genetic variation (-765GC) was 2.41 times higher among the controls than among the MI and stroke patients. The prevalence of a different variant (-765CC) was 5.81 times higher among the controls than among the MI and stroke patients. Patients with the -765GC or -765CC genotype had a reduction in relative risk of MI and ischemic stroke of 52 percent and 67 percent, respectively, after adjustment for age, sex, smoking status, body mass index, hypercholesterolemia, hypertension, and diabetes.

"We found that the -765GC polymorphism of the COX-2 gene is associated with a reduction in the risk of MI and stroke, suggesting that this [variation] may offer protection against clinical events related to atherosclerotic plaque rupture," the authors write.

Editor’s Note: This study was supported in part by grants from the Italian Ministry of Research and Education and the Italian Ministry of Health.

Im Focus: Spider silk key to new bone-fixing composite

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.

Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.

Im Focus: Gamma-ray flashes from plasma filaments

Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.

Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.

Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
