雌激素的心脏保护作用——与β_1-肾上腺素受体的相互作用及其信号通路(英文)

生理学报 2007年第5期59卷 571-577页

雌激素是女性体内主要的类固醇性激素。对于心肌缺血性伤害,切除卵巢的成年雌性大鼠在β-肾上腺素受体激动时,比正常雌性大鼠呈现更严重的心肌损伤;而去卵巢后的雌激素替补组大鼠对β-肾上腺素受体激动时心肌缺血性伤害的反应则又回复... 详细信息

雌激素是女性体内主要的类固醇性激素。对于心肌缺血性伤害,切除卵巢的成年雌性大鼠在β-肾上腺素受体激动时,比正常雌性大鼠呈现更严重的心肌损伤;而去卵巢后的雌激素替补组大鼠对β-肾上腺素受体激动时心肌缺血性伤害的反应则又回复到正常雌性大鼠水平,这为雌激素对抗缺血性伤害的心脏保护作用提供了证据。雌激素的这种保护作用是通过下调β1-肾上腺素受体的表达来实现的。也有研究证明,雌激素能抑制蛋白激酶A(protein kinase A,PKA)的表达和活性,PKA是Gs蛋白/腺苷酸环化酶(adenylyl cyclase,AC)/cAMP/PKA通路的第二信使,而该通路最终影响心肌的收缩功能。有初步证据表明雌激素还能抑制β1-肾上腺素受体通路下游的另一种第二信使钙调蛋白激酶II-δc(Ca2+/calmodulin kinase II-δc,CaMKII-δc)的活性,而CaMKII-δc参与PKA非依赖性的细胞凋亡。即时给予生理浓度雌激素可不通过雌激素受体而直接抑制心肌β1-肾上腺素受体并减弱Ca2+内流。此外,脑研究也显示雌激素能抑制负责调节动脉血压脑区的β1-肾上腺素受体活性。因此,雌激素和β1-肾上腺素受体之间的相互作用及其信号通路十分复杂。雌激素不仅主导性别决定,在机体其它功能例如心脏保护方面也具有重要作用。

澳门朱大仙信仰是澳门一个规模小的民间俗神信仰。即使从20世纪20年代算起,至今亦已有近百年历史,其盛衰与澳门渔业发展息息相关,皆因其信仰群体是由以澳门为港口的港澳渔民组成。80年代以前,澳门渔业兴盛,渔民人数众多,其中部分渔民供奉朱大仙,并每年在水面举行醮会,祈福消炎,在澳门曾出现三坛以供奉佛祖、观音、朱大仙的醮会。可惜,80年代以后,澳门渔业开始式微,加上政府海关政策的限制,使澳门渔民数量锐减。在社会转型的情况下,导致澳门朱大仙信仰面临消亡的危机。因此,政府、社会、民间应对这项非物质文化遗产的保护工作给以重视和支持。
