telomere gradual

British scientists discovered that telomere gradual depletion of the pathogenesis of heart disease may play a key role. They conducted a new study shows that often the author's heart telomere than healthy people much shorter. Telomere-end cell chromosome is the centromere. Human cells each split time, will be shortened telomeres, when the telomere short得不could short-term, you can not split the cells died. In the process of cell division, telomeres extent of the depletion vary from person to person. Elderly, children shorter than telomere length, it is because of the elderly after several separatist, more because of telomere attrition. According to "New Scientist" magazine reported that the British University of Leicester and Glasgow University researchers used five years of follow-up survey in 1542, aged 45 and 64 men between the ages of 5-year period 484 people suffering from heart disease . Comparative study found that people with shorter telomeres risk of heart disease is double the others. The study also found that the effectiveness of cholesterol-lowering statin drugs can reduce it seems that telomere attrition, not even the telomere degradation. Responsible for the study of Leicester University cardiologist Naier Shen Sa Mani said that his team has already begun laboratory studies, analysis of how these drugs have an effect on the telomere.
