雌激素缺乏是导致骨质疏松的重要原因之一。雌激素治疗骨质疏松症的临床疗效已获得普遍认可,其抗骨质疏松的作用,主要是通过促进成骨细胞增殖而产生效应。关于雌激素促成骨细胞的增殖,区别于经典的核效应,由雌激素膜受体介导的非核效应已成为研究热点。然而目前成骨细胞中非核效应的信号转导机制尚存争议。非核效应在成骨细胞中具体通过何种路径如ERK/MAPK通路、PI3K/Akt通路、Ca2+通路及新型雌激素受体GPER介导的信号通路产生效应尚无统一认识。故本文就目前已提出的非核效应信号转导途径学说及研究进展进行介绍。
雌激素缺乏是導緻骨質疏鬆的重要原因之一。雌激素治療骨質疏鬆癥的臨床療效已穫得普遍認可,其抗骨質疏鬆的作用,主要是通過促進成骨細胞增殖而產生效應。關于雌激素促成骨細胞的增殖,區彆于經典的覈效應,由雌激素膜受體介導的非覈效應已成為研究熱點。然而目前成骨細胞中非覈效應的信號轉導機製尚存爭議。非覈效應在成骨細胞中具體通過何種路徑如ERK/MAPK通路、PI3K/Akt通路、Ca2+通路及新型雌激素受體GPER介導的信號通路產生效應尚無統一認識。故本文就目前已提齣的非覈效應信號轉導途徑學說及研究進展進行介紹。

Estrogen deficiency is one of the important causes of osteoporosis .The curative effect of estrogen in the clinical treatment of osteoporosis has won the general recognition .Its anti-osteoporosis effect is mainly through the effect on osteoblast proliferation .Different from the classic nuclear effects , non-nuclear effect mediated by estrogen receptor becomes the hot topics currently in the contribution of estrogen to osteoblast proliferation.However , the signal pathway mechanism of non-nuclear effect in osteoblast is still controversial . The signal pathways include ERK/MAPK pathway , PI3K/Akt pathway , Ca2+pathway and a novel estrogen receptor signaling pathway mediated by GPER .There is not unified understanding in which is the right signal pathway that make non-nuclear effect in osteoblasts .Thus this paper introduces the signal transduction theories of non-nuclear effects and the research progress in recent years .
