项目摘要
In order to examine the role of Epac1 (exchange protein directly activated by cyclic AMP) on cardiac fibrosis, chronic isoproterenol (ISO) infusion (60mg/kg/day for 7 days) was performed in Epac1-null mice (Epac1KO) and wild-type controls (WT). Cardiac fibrosis was significantly inhibited in Epac1KO, compared to WT. In order to examine the mechanism, we examined the role of Epac1 in the following 3 steps : Step-1) Production of collagen fiber Step-2) Cross-linking of collagen fiber by lysyl oxidase (LOX) Step-3) Degradation of collagen fiber by matrix mettaloproteinase (MMT). Our data in this study shows that cardiac fibrosis was reduced through the inhibition of step-3.
为了检查Epac1(由环AMP直接激活的交换蛋白)对心脏纤维化的作用,在Epac1缺失小鼠(Epac1KO)和野生小鼠中进行慢性异丙肾上腺素(ISO)输注(60mg/kg/天,持续7天)。类型控制(WT)。与 WT 相比,Epac1KO 的心脏纤维化受到显着抑制。为了研究其机制,我们研究了 Epac1 在以下 3 个步骤中的作用: Step-1) 胶原纤维的产生 Step-2) 通过赖氨酰氧化酶 (LOX) 交联胶原纤维 Step-3) 胶原蛋白的降解通过基质金属蛋白酶(MMT)产生纤维。我们在这项研究中的数据表明,通过抑制步骤 3,可以减少心脏纤维化。
