双酸盐 (BPs) 通过影响细胞生长和衰老,显示出新的骨外益处. 这项研究揭示了BP.
科学领域:
- 老年学是一门学科.
- 分子生物学分子生物学
- 药理学 药理学是指药理学的学科.
背景情况:
- 双酸盐 (BPs) 是已确立的治疗骨质损失疾病的方法.
- 新出现的证据表明,BP具有显著的骨外益处,包括降低死亡率和改善与年龄相关的疾病.
- 这些好处可能会延伸到癌症和心血管疾病.
研究的目的:
- 为了研究双酸盐的非骨效应.
- 为了确定双酸盐在骨之外的新机制和细胞点.
- 探索双酸盐对衰老和衰老的影响.
主要方法:
- 用BP治疗的老年小鼠的空间转录组学.
- 5000倍复数血蛋白质组分析在骨质疏松患者在血压治疗之前和之后.
- 在体外衰老试验和全蛋白质组的目标解卷 (2D热分析).
- 对BP治疗细胞和患者数据的RNA和ATAC-seq分析.
主要成果:
- 双酸盐与内体/解体细胞器官共同局部化,并在低剂量时刺激非骨细胞生长.
- 高血压治疗改变了老鼠多个器官的衰老标志物和细胞组成,转向更年轻的个人资料.
- 血蛋白质组分析揭示了大约400种蛋白质的显著变化,包括衰老,自,亡和炎症的标志物,在BP治疗后的骨质疏松患者中.
- 蛋白质蛋白证明了对体外衰老开始的保护.
- 确定了新的BP目标 (PHB2,ASAH1),这表明心脏中MEF2A的下游调节.
结论:
- 双酸盐通过新型蛋白质相互作用有益地改变血蛋白质组,并影响非骨细胞类型.
- 这些影响影响了与衰老和衰老相关的途径,为治疗提供了新的可能性.
- 这些发现为观察到的双酸盐在骨外的益处提供了分子基础.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
