  • Localization of Estrogen Receptor β Protein Expression in Adult Human Bone
    作者:Isobel P. Braidman、Linda Hainey、Gaurav Batra、Peter L. Selby、Philippa T.K. Saunders、Judith A. Hoyland

    Evidence suggests that the newly described estrogen receptor β (ER‐β) may be important for estrogen (17β‐estradiol) action on the skeleton, but its cellular localization in adult human bone requires clarification. We addressed this by using indirect immunoperoxidase with a novel affinity purified polyclonal antibody to human ER‐β, raised to hinge domain (D) sequences from the human receptor. Bone was demineralized in 20% EDTA and all biopsy specimens were formalin‐fixed and wax‐embedded. Vigorous retrieval was essential for ER‐β detection. In sections (5 μm) of benign prostate hyperplasia, used as positive control, clear nuclear immunoreactivity was seen in glandular epithelial cells, with a 1:500 dilution of ER‐β40. For bone sections, optimal antibody dilutions were 1:100–1:250. We found that in normal bone (from graft operations), in fracture callus from both men and women (>25 years old), pagetic bone, osteophytes, and secondary hyperparathyroid bone, all from older patients, ER‐β was expressed clearly in osteoclast nuclei, with little cytoplasmic immunoreactivity. Nuclear immunoreactivity was still prominent in osteoclasts, with antibody diluted 1:500, although it faded in other cells. Osteoblasts, in areas of active bone formation or bone remodeling, also expressed ER‐β, as did some osteocytes. However, hypertrophic chondrocytes were negative, unlike mesenchymal cells, adjacent to the osteogenesis. Megakaryocytes and some capillary blood vessels cells were receptor positive. All ER‐β expression was blocked totally by preincubation of antibody with antigen. We conclude that ER‐β is expressed in cells of osteoblast lineage and in osteoclasts. The latter appear relatively abundant in this receptor and this might provide a means for direct action of estrogen on osteoclasts.
    有证据表明,新描述的雌激素受体β(ER-β)对于雌激素(17β-雌二醇)在骨骼上的作用可能很重要,但它在成年人类骨中的细胞定位需要阐明。我们通过使用一种新型亲和纯化的针对人类ER-β的抗体,该抗体是针对人类受体铰链域(D)序列制备的多克隆抗体,采用间接免疫过氧化物酶法来解决这个问题。骨组织用20% EDTA脱矿,所有活检标本均经甲醛固定并石蜡包埋。对于ER-β的检测,充分的抗原恢复是必要的。在作为阳性对照的良性前列腺增生切片(5 μm)中,腺上皮细胞中可观察到明显的核免疫反应性,使用1:500稀释度的ER-β40抗体。对于骨切片,最佳抗体稀释度为1:100至1:250。我们发现,在正常骨(来自移植手术)、男性和女性的骨折骨痂(>25岁)、佩吉特骨病、骨赘以及来自老年患者的继发性甲状旁腺功能亢进骨中,ER-β在破骨细胞核中表达明显,胞质免疫反应性很低。即使在1:500抗体稀释的情况下,破骨细胞中核免疫反应性仍然显著,尽管在其他细胞中有所减弱。成骨细胞,在活跃的骨形成或骨重建区域,也表达了ER-β,一些骨细胞也是如此。然而,肥大的软骨细胞为阴性,与邻近的成骨的间充质细胞不同。巨核细胞和某些毛细血管内皮细胞为受体阳性。所有ER-β的表达均可通过预先与抗原孵育的抗体完全阻断。我们得出结论,ER-β在成骨细胞系和破骨细胞中均有表达。后者似乎相对富含此受体,这可能为雌激素直接作用于破骨细胞提供了途径。
