科学家发现某种基因的变异能上调一种炎症酶,而这种情况似乎偏重于女性。该基因是白三烯C4合酶(LTC4S)基因的启动子,这一变异基因增加白三烯的合成。研究者提出:这是首个报道LTC4S DNA序列变异与心血管疾病早期标志物关系的研究。之所以选择这一基因进行研究,是因为已知半胱氨 Scientists have found that a mutation in a gene can up-regulate an inflammatory enzyme, a situation that seems to favor women. This gene is the promoter for the leukotriene C4 synthase (LTC4S) gene, which increases the synthesis of leukotrienes. The researchers propose: This is the first study to report the association of LTC4S DNA sequence variations with early markers of cardiovascular disease. The reason for choosing this gene is because cysteamine is known
