性类固醇激素、雄激素和雌激素通过各自的核受体调节人类和小鼠的骨矿物质密度。我们对骨细胞中雄激素和雌激素受体的直接作用靶点知之甚少。首先,讨论了小鼠和人类骨骼中激素和受体缺乏的模型。本文综述了受体在成骨细胞和破骨细胞中的直接作用靶点。NR的直接靶标在这里被定义为受NR与DNA结合(通过DNA结合或与DNA结合蛋白结合)在该基因的增强子或启动子上调节的基因。本文将总结雄激素和雌激素基因在成骨细胞和破骨细胞中调控的实验证据,并与体内激素的表型进行比较。
The sex steroid hormones, androgens and estrogens, via their respective nuclear receptors, regulate bone mineral density in humans and mice. Very little is known about the direct targets of the androgen and estrogen receptors in bone cells. First, models of hormone and receptor deficiency in mouse and human bone are discussed. This review then focuses on the direct targets of the receptors in osteoblasts and osteoclasts. A direct target of a NR is defined here as a gene that is regulated by NR binding to the DNA (either through DNA binding or association with a DNA binding protein) at an enhancer or promoter of that gene. The experimental evidence that illustrates androgen and estrogen gene regulation in osteoblasts and osteoclasts will be summarized and compared with the phenotype of the hormones in vivo.
